#49 Aspiration | Book Review

Aspiration: The Agency of BecomingAspiration: The Agency of Becoming by Agnes Callard
My rating: 4 of 5 stars

What kind of book is this?
This is an expository work.

Rational & Why I read this book
I have a Substack called Fractal Productivity and wanted to deepen my knowledge of "aspiration" before writing an essay series on vertical life sculpting

The unity of the book — what is the book about as a whole?
This book is a philosophical account of why aspiration (defined as "large-scale transformative pursuits" and "a gradual process of value change") should be seen as a form of "practically rational agency". Put simply: the book shows how and why people who aspire actively shape their future selves throughintentional efforts. Aspiration, according to the author, should be seen as something rational rather than irrational or arational, as it currently seems to be perceived by philosophers.

The book's structure
The book spans a long introduction and 6 chapters across 277 pages. It is further divided into three parts, each of which houses two chapters. These parts are "practical rationality", "moral psychology" and "moral responsibility". I completed a reading of the whole book but analytically focused most on part 1.

One particular lesson
One particularly interesting concept Callard posits is "proleptic reasons." This is a new "species" of reason that allows us to explain why something as vague and distant and not fully present in the aspirant's mind could considered "rational." Proleptic reasons capture the fact (?) that one can act rationally even when one doesn't know fully one's reason for doing something or if one knows one's reasons for doing it isn't exactly the right one. A proleptic reason for doing something is a reason where an agent acts on a rudimentary, anticipatory, and indirect "grasp" of something. The person's knowledge and development areprovisional. Callard argues that aspirations are based on agents' proleptic reasons.

Judgement & Recommendations - Who should read this?
I'm neither a philosopher nor an academic, and English is not my mother tongue. This book would still be hard to read even if all of this were the case. A big part was the overly awkward writing style! I certainly also lack the knowledge of philosophy and perfect English skills. Granted, the reading went much smoother on the second pass (done immediately after the first). After summarizing the book (at least part 1), I now feel that I have a somewhat firm grasp of what Callard is trying to say. And I have to say, it immediately impacted my way of viewing aspirations and values. Still, I can't rate this book higher than a 7/10 on my personal rating scale, which means this is a "Good read, despite minor weaknesses; generally recommended". The ideas are powerful, but the packaging feels off to non-philosophers and non-academics without English as a mother tongue.
Positive points
- As far as I can tell, Callard makes compelling arguments. At this point, I cannot refute any of her points.
- Callard's ideas are high caliber, and she has given this topic much thought.
- Callard is humble, and the book is more of a defense than a series of claims.

Negative points
- Callard's writing style is really hard to digest. I understood less than 70% of it on the first pass, maybe less.
- the book could have been carved down significantly without losing power.

Misc. comments and other remarks
I don't recommend this book unless you are motivated to understand the philosophy of aspiration. Luckily, I was highly motivated to understand the book (see rationale above), but it took me almost two months to complete it because the writing style led me to procrastinate.

#48 Atomic Habits | Book Review

Atomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad OnesAtomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad Ones by James Clear
My rating: 3 of 5 stars

What kind of book is this?
This is an expository work; more specifically, a practical self-help book.

Rational & Why I read this book
2022 is my "year of kaizen". I place a strong focus on making tiny improvements on a daily/weekly basis and building better habits are at the core of this endeavor. Atomic Habits seemed to be a perfect fit. I already had listened to it as an audiobook a couple of years back and the book gained a lot of traction recently.

The unity of the book — what is the book about as a whole?
The book is about personal transformation and the road to mastery.
The author introduces a system, which advocates small ("atomic") changes and revolves mainly about designing ones habits. 4 "laws" of behaviour change are presented: Make it obvious. Make it attractive. Make it easy. Make it satisfying. These easy to remember guidelines are supposed to help with shaping and designing ones life and advancing toward mastery in one's strong areas.

The book's structure
The book has 6 parts with 3-4 chapters each (20 chapters in total) and has a total of about 250 pages:
1. The Fundamentals - Why Tiny Changes Make a Big Difference
2. The 1st Law - Make It Obvious
3. The 2nd Law - Make it Attractive
4. The 3rd Law - Make it Easy
5. The 4th Law - Make it Satisfying
6. Advanced Tactics
The book summarises itself quite often and overall is summarised in a single table of the 4 Laws of Behaviour Change. There is also an Appendix with some further ideas of the author.

One particular lesson
I took 153 highlights; one of my favourites being: "The first mistake is never the one that ruins you. It is the spiral of repeated mistakes that follows. Missing once is an accident. Missing twice is the start of a new habit." (p.200)

Judgement & Recommendations - Who should read this?
TL;DR: overall, I assign this book a 6/10 (★★★). It is OK; slightly above average but in my opinion has tangible weaknesses.

I still recommend you to read the book with some reservations. Upfront, the good: if you have never read anything about habit design, I think this book will be as good as any other in getting you started. Habits, after all, are a central theme in self-improvement and even raising your awareness of their role in your life can help you. This book can definitely do that for you. The book contains some good thinking and several intriguing ideas and tips. The author also summarizes his guidelines into his 4 basic "laws" of habit design which are easy to remember and to take with you in your daily life. I like that he tries to give credit to everything he "borrowed" from others (even though sometimes his approach is quite fishy - e.g. he several time uses phrases like "was inspired by" when something was downright stolen and minimally adapted to his cause). I further appreciates that Clear also does explore some downside of habits and does not leave you with the impression that habits or his system are the magic bullet for all things. As a bonus, I like how the footnotes are organised. That being said, like many self-help book authors, Clear has no special "qualifications" to write this book. He manages to deliver mediocre to good tertiary literature (e.g. as opposed to Tiny Habits written by someone who actually conducted many of the experiments in habit design). Overall, many of his claims are backed by reasons and sources (often he only brings anecdotal internet sources, but several times he also highlights scientific studies). However, quite often there are also claims mixed in, made totally out of the blue, without any backing of any kind e.g. in chapter 10 where he talks about "where cravings come form"; I guess that's just his personal experience mixed in without making the reader aware of that. In my opinion, Clear also misnamed his book. This book has surprisingly little to do with the "atomic" part of habits, as the title suggests. After finishing the book I had the feeling that of 250 pages in total no more than 20 are qualified to be called dedicated to the fact that making habits "really small" is important. Two other books – Tiny Habits and especially Mini Habits – do a way better at staying true to their title. What Clear does instead is what many self-help books end up to do: trying to deliver a whole system for self improvement. Implicitly, Clears focus is also mostly on building habits as part of skill building on the way to mastery, less about every day habits you would think about when picking up such a book. What troubles me the most, however, is that the quality of the content does not remain constant thought the book - some parts are really good (what he writes about identity change and habit tracking), many are OK, several are just bad and wrong (e.g. his take on goals - in the beginning of the the throws out "goal setting" completely, while at the same time he "admits" his goal-driven approach in writing this very book and also explains the importance of "deliberate" work ). Lastly, the fact that he starts every chapter with a somewhat unnecessary and unrelated story, is a personal distaste of mine. To sum up, I think that this book does not deserve the fame it currently receives. It is not popular due to its content, but its content is there because it was made popular. Something that probably happens quite naturally when an author repurposes his blog posts into a book, then leverages his newsletter audience to make it an instant success on Amazon. The book could be better (7/10) if half of the content was simply cut out.

#40 Mini Habits | Book Review

Mini Habits: Smaller Habits, Bigger Results (Mini Habits, #1)Mini Habits: Smaller Habits, Bigger Results by Stephen Guise
My rating: 4 of 5 stars

What kind of book is this?
This is an expository work; more specifically, a practical self-help book.

Rational & Why I read this book
2022 I will work on a lot of my habits. I picked this short book as a preparation for my yearly planning session.

The unity of the book — what is the book about as a whole?
This book introduces and guides you step-by-step through the process of creating and cultivating "mini habits" in your life; that is, habits that are so small that they are so stupidly easy that there is no reason not to do them. An example would be to do 2 push-ups after going to the toilet.

The book's structure
The book has 8 chapters across 120 pages:
1. Introduction to Mini Habits
2. How Your Brain Works
3. Motivation Vs. Willpower
4. The strategy of Mini Habits
5. The Mini Habits Difference
6. Mini Habits — Eight Small Steps to Big Change
7. Eight Mini Habit Rules
8. Final Words

One particular lesson
Though a very short read, I highlighted a lot. One idea, totally new to me, was what the author calls freedom-based, non-specific habit cues: if you not only target one specific cue for a habit but instead multiple ones, you end up with a much more flexible and sustainable habit. Caveat: this is only possible if you start with very tiny habits.

Judgement & Recommendations - Who should read this?
My recommendations are largely based on whether I think how many people could benefit from reading a given book. I consider the content, the style, and a "value-per-pages". To my surprise, I found this short and highly practical book to be a very worthwhile my time; even for people who don't read that much I think I generally would recommend this since it is concise, approachable, contains a lot of practical advice, and is not too long in total. That is why I recommend you give this a try. Unlike the two big books on the topic of "small habits"— Tiny Habits: The Small Changes That Change Everything and Atomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad Ones — Mini Habits is the only one that focuses on the "mini" throughout the whole book. If you were only to read one of these three books, you should pick BG Foggs Tiny Habits, as BG Fogg is the only "true" expert on the subject matter. Otherwise, read all three of them and build your own opinion and pick what of it works for you. I rate Mini Habits a 7 out of 10 (⭑⭑⭑⭑) on my personal rating scale, which means: "Good read, despite minor weaknesses; generally recommended.".

#39 How to Read a Book | Book Review

How to Read a Book: The Classic Guide to Intelligent ReadingHow to Read a Book: The Classic Guide to Intelligent Reading by Mortimer J. Adler
My rating: 5 of 5 stars

What kind of book is this?
This is an expository work; more specifically, it is a practical guidebook.

Rational & Why I read this book
2021 I is set out to become a "better" reader. One metric I had for measuring this, was reading and reviewing 52 books (my 2021 Goodreads challenge) within a year. Another metric was to finally give "How to Read a Book" itself an analytical read, after having read it casually a couple of times already.

The unity of the book — what is the book about as a whole?
This book guides you in becoming a "better" reader, someone who reads to gain wisdom instead of acquiring knowledge or being entertained. In doing so, this book sets forth many nuances (e.g. the kind of the book— theoretical vs. practical, fiction vs. expository) that need to be taken into consideration when reading for "enlightenment"; giving a special focus on the different "levels of reading" that one must master; starting as primitive as how to learn to read in school (elementary reading) and going as advanced as reading multiple books on the same topic at the same time in order to fully grasp a topic and to distill a discourse on it (synoptical reading).

The book's structure
The book has four major parts.
In the first part, after a short introduction on reading and its goals itself, it introduces and explains the 4 "levels" of reading, namely elementary reading (basic reading as learned in school), inspectional reading (systematic skimming or pre-reading), analytical reading, and synoptical reading. All of them are briefly discussed.
In the second part it goes in-depth on the most important level of reading as far as the book is concerned: analytical reading. It shows the various "stages" that are involved in this level, including deep-diving into the matter, "coming to terms" with the author, and criticizing a book fairly, and clearly highlighting the 10 most important rules to follow when reading on this level.
In the third part it shows approaches to different kinds of reading matter; specifically it shows how to read practical books, imaginative literature, stories/plays/poems, history, science & math, philosophy, and social science.
In the fourth part it goes more into detail about synoptical reading - reading multiple books on the same topic at the same time - and ties together the rationale for reading in the first place: the growth of the mind.

One particular lesson
Since I read this analytically, it is really hard to pick one single thing here. One that is short enough to elaborate here is the insight, that different books should be read at different speeds which not merely refers to reading speed in words per minute. Instead, this means some books do not even deserve 10 minutes of skimming while others you should read very deeply, slowly, and many times over the course of your life. Personally, I think to truly understand this lesson you need to first read a lot of books (100+), so that you can experience the big range of quality there is. Else you will probably not even know that most of what you are reading is not worth your time at all.

Judgement & Recommendations - Who should read this?
This is a true classic and — to the best of my knowledge — the definitive book on reading there is. Sure, many years have passed since its publication and it definitely could need a revision, since it does not take into account the advancement in science and technology. But, rather than dismissing it as "dated", I think this book is relevant more than ever. It is a long book and not an easy read, but for everyone that (1) likes to read (2) aims to leverage reading to gain wisdom (3) cares about personal growth (growth of the mind in particular), this is a definitive reading recommendation. Overall, I appoint it a 9 out of 10 (⭑⭑⭑⭑) on my personal rating scale.

#38 Rational Choice in an Uncertain World | Book Review

Rational Choice in an Uncertain World: The Psychology of Judgement and Decision MakingRational Choice in an Uncertain World: The Psychology of Judgement and Decision Making by Reid Hastie
My rating: 3 of 5 stars

What kind of book is this?
This is an expository work; more specifically, it is a theoretical textbook.

Rational & Why I read this book
2021 is my year of ratio & will. I try to read various books with various angles on rationality. A highly scientific standpoint should of course also be part of that.

The unity of the book — what is the book about as a whole?
This is a book about rational decision-making based on what we know about it from science (I read the 2001 version).

The book's structure
The book has 14 main chapters with 4-7 subchapters each (350 pages).
1. Thinking and Deciding
2. What Is Decision Making?
3. A General Framework for Judgment
4. Judgments From Memory
5. Anchoring and Adjustment
6. Judgment by Similarity
7. Judging by Scenarios and Explanations
8. Thinking About Randomness and Causation
9. Thinking Rationally About Uncertainty
11. Evaluating Consequences: Simple Values
12. Complex Values and Attitudes
13. A Normative, Rational Decision Theory
14. In Praise of Uncertainty
X. Appendix on the basic principles of probability theory.

One particular lesson
A passage I found relevant for my personal life:
"Children who see little contingency between their own behavior and their rewards and punishments often behave badly, or at least we can improve their behavior by increasing the contingency. In addition, employees who believe that they have control over the rewards they receive for their work are motivated to work hard and be productive. Consequently, employers and supervisors are well advised to establish a contingency between employee accomplishments and rewards. ... Rationally, it often doesn't matter how much control we have over outcomes-so long as we have some" (p. 324)

Judgement & Recommendations - Who should read this?
This is a textbook intended for students, albeit a somewhat approachable one. It took me several weeks to finish and I even skipped one chapter which I didn't find relevant for me. Therefore, I would not recommend this as a whole to the average reader. If you are researching a certain topic or if you have a deep interest in one of the covered topics, you maybe can use it as a reference work (read-only part of the book and fetch the mentioned resources). Otherwise, I'd recommend you choose other books like Tools Of Critical Thinking: Metathoughts For Psychology and The Art of Clear Thinking (if you are interested in improving your thinking in practice) instead. They are of a more practical nature. Overall, I appoint it a 6 out of 10 (⭑⭑⭑) on my personal rating scale.

#37 Analyze Yourself | Book Review

Analyze Yourself: Enabling Anyone to Become Deeply Psycho-Analyzed Without a Personal AnalystAnalyze Yourself: Enabling Anyone to Become Deeply Psycho-Analyzed Without a Personal Analyst by E. Pickworth Farrow
My rating: 2 of 5 stars

What kind of book is this?
This is an expository work; while it contains a practical guide (the practical method mentioned in the title), it mostly resembles personal experiences and anecdotes by the author.

Rational & Why I read this book
To know thyself. Self-Analysis promises to help with that. That is why I put this short, old book on my reading list when I stumbled upon it.

The unity of the book — what is the book about as a whole?
The book takes you on a journey through the author's life experiences and insights he personally had with Self-Analysis. He builds upon, then alters and extends Freund's methods and proposes a practical way to uncover deeply routed deficiencies and complexes in oneself that date back to infancy.

The book's structure
No lesser than Sigmund Freud himself wrote the foreword to this book.

The book then contains two prefaces and 10 chapters:
1. Origin of the Author's Interest in Psycho-Analysis
2. Experiences with two Psycho-Analysits
3. A Practical Method of Self-Analysis
4. A Castration Complex
5. An Experience in Infancy and its Effects
6. A Memory Going Back to the Age of Six Months
7. On the Psychological Importance of Slaps and Blows in Early Infancy
8. On the Importance of avoiding Castation Threats against Children
9. Psycho-Analysis and Early Complexes
10. Additional Notes

One particular lesson
The proposed method of free-association can be summarised as follows: Put aside some quiet time free from interruptions. Prepare pen and Paper. Now simply allow thoughts arise freely without criticising anything or holding anything back and write down whatever comes into your conscious mind at any given instant (no matter how absurd or seemingly useless; i.e. even thoughts like "this is silly", "this is a waste of time", "this does not work" etc. should simply put down to paper). Doing this for weeks or months is supposed to lead to insights and even recovering memories from your infancy. I immediately recognised to how similar this method is to the now so popular morning pages proposed by Julia Cameron in The Artist's Way: A Spiritual Path to Higher Creativity.

Judgement & Recommendations - Who should read this?
Don't read this. It's outdated, strange. Not much more to say. The method as described above surely is worth trying out, but I consider the book itself a waste of time. One for me deeply annoying fact is that the author refers to himself as "the author". Overall, this is a 4 out of 10 (⭑⭑) on my personal rating scale which translates into "Rather bad; personally finished, but definitely would not give it a second read."

#35 Time to Think | Book Review

Time to Think: Listening to Ignite the Human MindTime to Think: Listening to Ignite the Human Mind by Nancy Kline
My rating: 2 of 5 stars

What kind of book is this?
This is an expository work; more specifically, it is a practical guidebook.

Rational & Why I read this book
2021 is my year of ratio & will. I try to read various books on rationality, discipline, and thinking in general. How to foster good thinking in groups seemed to be a good fit; I also anticipated some learnings to apply at work.

The unity of the book — what is the book about as a whole?
This book introduces the "thinking environment" — an environment where everyone is enabled to think for themselves — and the ten components that according to the author are needed to build such an environment. It explores how to build such a "think tank" and how it fits into society at large.

The book's structure
The book has four parts:
1. A Thinking Environment: Its Ten Components
2. Creating a Thinking Environment
2. The Thinking Society
3. A Thinking Future

One particular lesson
A nice statement I want to remember:
"Until we are free to think for ourselves, our dreams are not free to unfold."

Judgement & Recommendations - Who should read this?
I appoint it a 4 out of 10 (⭑⭑) on my personal rating scale: rather bad; finished, but definitely would not give it a second read. While I find a few good thoughts here and there, I would not recommend it.

#34 The Mature Mind | Book Review

The Mature MindThe Mature Mind by Harry Allen Overstreet
My rating: 5 of 5 stars

What kind of book is this?
This is an expository work of theoretical nature.

Rational & Why I read this book
My reasons were twofold: (1) 2021 is my year of ratio & will. I try to read various books on rationality, discipline, and the mind in general. (2) The topic of "maturity" is a highly relevant one in personal growth, a topic very dear to me.

The unity of the book — what is the book about as a whole?
Existing psychological insights at the time (conditioning, psychological age, arrested development, aptitude uniqueness, and the capacity of the adult brain to learn) are brought together into what the author calls the "maturity concept". Maturity refers to the growth of the mind. Just like the body needs to be fostered with nutritious food in order to grow, the mind needs certain input, certain impulses to mature. Otherwise, people end up with grown-up "child-minds". How to avoid that and the implications of these insights on society, education, politics, ... are explored.

The book's structure
The book has two parts.

In the first part, the author explains his maturity concept:
1. Psychological Foundations
2. Criteria of Maturity
3. Two old theories and a new one
4. Mature insights lost on immature minds

In the second part he elaborates on how this concept fits in with the "forces that shape us":
5. A heritage of contradictions
6. Applied maturity: a test case
7. Economics for human fulfillment
8. The play of politics on the mind
9. What we read, see, and hear
10. The home as a place for growing
11. Education: a question mark
12. Toward religious maturity
13. What we ourselves can do

One particular lesson
One passage from the book when he talks about the negative effects of radio on our maturity (remember, it is 1949): "One mark of the psychological growth of the human being, from infancy through childhood and into adulthood, is the lengthening of the attention span. The immature mind hops from one thing to another; the mature mind seeks to follow through. ... Whatever other influences it may exert for our maturing, radio is on the side of lifelong immaturity in the constant invitation it offers us to develop hopscotch minds."

I wonder what he would have to say about social media and smartphones in today's world...

Judgement & Recommendations - Who should read this?
There is a reason this was a substantial best-seller that sold over 500,000 copies back in the 50s. What Overstreet writes is smart, concise and deeply needed to be heard by people; now — 70 years later — more than ever. I will have to give it a second, deeper reading, to get even more out of it. I will also look in Overstreet other books. I appoint this a 9 out of 10 (⭑⭑⭑⭑⭑) on my personal rating scale and recommend it to anyone who can get hold of a copy.

#33 Im Zaubergarten der Gedanken | Book Review

Im Zaubergarten der Gedanken. Einfälle.Im Zaubergarten der Gedanken. Einfälle. by Georg Christoph Lichtenberg
My rating: 4 of 5 stars

What kind of book is this?
This is a theoretical expository work; more specifically, it is a collection of philosophical aphorisms.

Rational & Why I read this book
This book made my 2021 reading list rather coincidentally; it was mentioned as a reference in The Mature Mind. I read it partly because it was recommended by Overstreet, partly because I haven't read a good book by a German author in while, and partly because it seemed to be a short and worthwhile read.

The unity of the book — what is the book about as a whole?
There is no plot, no unity to be found in this book since it is merely a collection of ideas in the form of short paragraphs.

The book's structure
The aphorisms presented in the book are divided into 8 "chapters" (rookie translations are mine).
1. The enigma of reality
2. The individual and the collective
3. The beauty of nature's plan
4. The world of books and art
5. About faith and superstition
6. About the power of love
7. About life afterlife
8. Observations, conceptions, dreams

One particular lesson
I made 69 highlights some of which were (my own translation):
- "The most scholarly are not always the ones with the best ideas."
- "Nothing ages your mind more quickly than constantly thinking about growing older"
- "I forget most of what I've read, just like I forget most of what I've eaten. But I know this: both nonetheless make for my mind and body."

Judgement & Recommendations - Who should read this?
This is a short and worthwhile read (if you are German). It invites to ponder and think. It inspires you to keep your personal log of aphorisms. Overall, I appoint a 7 out of 10 (⭑⭑⭑⭑) on my personal rating scale.

#32 Refactoring | Book Review

Refactoring: Improving the Design of Existing CodeRefactoring: Improving the Design of Existing Code by Martin Fowler
My rating: 4 of 5 stars

Context & Why I read this book
I am a software engineer with a focus on mobile applications and was looking for a more systematic approach to safely rewriting code without causing regressions. Such methodical "refactoring" is a valuable skill for developers; especially in enterprise settings where one works on large codebases with many contributors. Further, Addison Wesley & Martin Fowler are renowned in the field of software construction.

What is the book about as a whole?
The author himself says that this is a guide for professional programmers on how to refactor code "in a controlled and efficient manner". He explains what refactoring is (and what not), how to do it properly and he gives many detailed and step-by-step code refactoring examples using the programming language JavaScript. (This review is about the second edition of the book, which appeared 18 years after the first edition, which used Java for code samples)

The book's structure
The book is divided into 12 chapters:
1. Refactoring, a First Example(the author deliberately leads with a very practical introduction instead of a theoretical one)
2. Principles in Refactoring(a more general and theoretical introduction to the concept of changing software systems without causing regressions)
3. Bad Smells in Code(a list of indications that show you _when_ to apply refactoring; unfortunately no code samples in this section)
4. Building Tests(A dedicated section on automated testing, since refactoring cannot be done without an appropriate test suite)
5. Introducing The Catalog
6. A First Set of Refactorings
7. Encapsulation
8. Moving Features between Objects
9. Organizing Data
10. Simplifying Conditional Expressions
11. Refactoring APIs
12. Dealing with Inheritance

Chapters 6-12 make up the "refactoring catalog", which contains 67 "refactorings" with names like:
- "Change Function Declaration"
- "Extract Function"
- "PullUp Method"
- "Replace Loop with Pipeline"

Each Refactoring contains a small graphic to memorize the refactoring, followed by a short and glanceable code example and a section on the motivation of the particular refactoring. Then there is the main part: a section called "mechanics" which is a detailed list of usually 5-12 steps on how to approach the given Refactoring followed by a detailed example with sample code.

The physical book comes with a free digital web version included.

One lesson
Rather than mentioning a particular refactoring or concrete advice from the book I want to take the lesson with me, that "Refactoring" is no island and only works properly in combination with self-testing code (automated tests), trunk based development (or continuous integration) and the general philosophy of opportunistically improving a code base little by little.

Reading Recommendation / Who should read this?
I think, that this book (in its second edition!) makes a good and valuable contribution by showing you that there is a more methodical and structured way of changing code. The book will not render you a refactoring expert since most of it (the catalog) is meant for reference instead of up-front learning (while containing many code samples, there are no exercise or challenges to solve and Fowler himself refers to William C. Wake'" Refactoring Workbook this regard). But even if it did, according to my limited experience in the field, in many (if not most) enterprise settings with legacy codebases and large teams there is not much hope that introducing this will ever work (see my lesson above). So while at the moment I don't see much practical relevance for myself I still consider it worthwhile to read this book for software engineers. Also, if you think this is wrong and your company successfully applies this, pls hire me.

All in all a 7 out of 10 (⭑⭑⭑⭑) on my personal rating scale ("Good read, despite minor weaknesses; generally recommended.")

#31 The Art of Clear Thinking | Book Review

The Art of Clear ThinkingThe Art of Clear Thinking by Rudolf Flesch
My rating: 4 of 5 stars

Context & Why I read this book
For 2021 I set myself the theme "a year of ratio & will"; so I am reading mostly on the topics of critical thinking, rationality, discipline, and willpower. Quite late I stumbled upon Flesch's "The Art of Clear Thinking" via the reference section of another book; a no-brainer to be added to my reading list for the year.

What is the book about as a whole?
As the title of this psychological self-help work suggests, Flesch explores what clear thinking is and how it can be achieved. He thereby takes you on an unexpected ride, touching the scientific fields of psychology, linguistics, anthropology, neurology, sociology, history, probability theory, and more.

The book's structure
The book has 21 chapters that are meant to be read in sequence:
1. Robots, Apes, and You
2. Nerves and Thoughts
3. Do You See What I See?
4. Of Thingummies and Whatchamacallits
5. Danger! Language at Work
6. The pursuit of Translation
7. First aid for word trouble
8. The Rise and Fall of Formal Logic
9. How Not to Be Bamboozled
10. Why argue?
11. Legal rules and Lively cases

One lesson
Flesch presents a tactic intended to solve ordinary-life problems like buying a family home; he calls it "Twenty Questions" since it simply means asking as many as 20 questions from different perspectives before starting to work on the problem. Asking such questions seems like a very suitable kick-off procedure for most of my growth projects or personal goals I set up. So I'll add his examples questions to my goal template:
- What am I trying to accomplish?
- Have I done this sort of thing before? How?
- Could I do this some other way?
- How did other people tackle this?
- What kind of person or persons am I dealing with?
- How can this situation be changed to fit me?
- How can I adapt myself to this situation?
- How about using more? Less? All of it? Only a portion? One only? Two? Several?
- How about using something else? Something older? Something newer? Something more expensive? Something cheaper?
- How near? How far? In what direction?
- How soon? How often? Since when? For how long?
- Could I do this in combination? With whom? With what?
- How about doing the opposite?
- What would happen if I did nothing?

Reading Recommendation / Who should read this?
This book is a 7 out of 10 (⭑⭑⭑⭑) for me. It's a good read, despite minor weaknesses (like that it is a little dated by now) I would generally recommend this book to most people.

#30 Liminal Thinking | Audiobook Review

Liminal ThinkingLiminal Thinking by Dave Gray
My rating: 2 of 5 stars

Context & Why I read this book
I am currently exploring rationality and critical thinking and never heard of the term "liminal thinking" before. Sounded interesting, so I gave it a try.

What is the book about as a whole?
The book is about the fact that we are limited by believes that we created unconsciously. And that there are ways to think and see through these limits in order to unblock ourselves for greater achievement.

The book's structure
2 parts, 15 chapters (titled "practices"):
PART 1: How Beliefs Shape Everything
1. Beliefs Are Models
2. Beliefs Are Created
3. Beliefs Create a Shared World
4. Beliefs Create Blind Spots
5. Beliefs Defend Themselves
6. Beliefs Are Tied to Identity
PART 2: What to Do About it
7. Assume Your Are Not Objective
8. Empty Your Cup
9. Create Safe Space
10. Triangulate and Validate
11. Ask Questions, Make Connections
12. Disrupt Routines
13. Act As If in the Here and Now
14. Make Sense with Stories
15. Evolve Yourself

One lesson
One thing I jotted down while listing to this and I want to take with me, was a quote from Marshall Mc Luhan: Once you see the boundaries of your environment they are no longer the boundaries of your environment. This reminded me of another quote by
Oliver Wendell Holmes, Jr.: "A mind that is stretched by a new experience can never go back to its old dimensions.” This is about the only note I took.

Reading Recommendation / Who should read this?
I don't know why there are so many good reviews here. I heard the audiobook version a while back and to be honest, I don't remember much; either because I already knew it, didn't agree with it, or just didn't care. It's short but I still don't recommend it. 3 out of 10 (⭑⭑) for me (which translates into "bad, but forced myself to finish; close to no nuggets to be found.")

#29 The Road Less Traveled | Book Review

The Road Less Traveled: A New Psychology of Love, Traditional Values and Spiritual GrowthThe Road Less Traveled: A New Psychology of Love, Traditional Values and Spiritual Growth by M. Scott Peck
My rating: 4 of 5 stars

Context & Why I read this book
"The Road Less Traveled" is a long-time bestseller in the area of psychology, self-help, and personal growth; topics I am interested in for nearly a decade now. It also includes several chapters on "discipline"; a topic I am currently exploring more deeply. So it was about time to finally tackle this work.

What is the book about as a whole?
Peck was a psychiatrist and author and he derived his "world view" mostly from his experience in his clinical work. In "The Road less Traveled" he tries to answer how to live a fulfilling life. For him, this meant to elaborate on the topics of Discipline, Love, and Spiritual Growth.

The book's structure
The book is divided into 4 parts:
I. Discipline which is about Problems, Pain, Delaying Gratification, Sins, Problem-Solving, Responsibility, Neuroses, Character Disorders, Freedom, Reality, Transference, Openness to Challenge, Truth, Balancing, Depression, Renunciation)
II. Love which approaches a definition of Love, Falling in "Love", Romantic Love, Ego Boundaries, Dependency, Cathexis, Self-Sacrifice, Feelings, Attention, Loss, Independence, Commitment, Confrontation, Separateness, Psychotherapy, Mystery)
III. Growth & Religion which is about Word Views, Religion, Several of his clinical cases, Scientific tunnel vision
IV. Grace which tackles the "miracles" of Health, the Unconscious, Serendipity, Grace, Evolution, Entropy, Evil, Consciousness, Power, Grace and Mental Illness

One lesson
There are two ways to confront a loved one when you feel to possess superior knowledge; you can do it either with arrogance or with humility. The truly loving person always chooses the latter by scrupulous self-doubting and self-examination in advance and even then always believing to be only "probably right".

Reading Recommendation / Who should read this?
While most of the book is very approachable, this is not a book for beginners. Especially the latter chapters that focus on spiritual growth require some previous contact with the topic in order to be digestible. Nonetheless, even if you only read the first two parts of the book it will benefit you greatly. So I give it an 8 out of 10 (⭑⭑⭑⭑) on my personal rating scale.

#28 A Little History of Philosophy | Book Review

A Little History of PhilosophyA Little History of Philosophy by Nigel Warburton
My rating: 4 of 5 stars

Context & Why I read this book
I listened to this as an audiobook on my last vacation in Greece since I read on some forum that it supposedly helps with better and more rational thinking.

What is the book about as a whole?
The book presents the most important philosophers and their ideas throughout the ages — starting in ancient Greece with Socrates and Plato and culminating with contemporary Australian philosopher Peter Singer. Philosophers discussed are Socrates, Plato, Aristotele, Pyrrho, Epicurus, Epictetus, Cicero, Seneca, Augustine, Boethius, Anselm, Aquinas, Machiavelli, Hobbes, Descartes, Pascal, Spinoza, Locke, Reid, Berkeley, Voltaire, Leibniz, Hume, Rousseau, Kant, Bentham, Hegel, Schopenhauer, Mill, Darwin, Kierkegaard, Marx, Peirce, James, Nietzsche, Freud, Russel, Ayer, Camus, Wittgenstein, Arendt, Popper, Kuhn, Foot, Thomson, Rawls, Turing, Searle, and Singer.

The book's structure
The book is divided into 40 chronologically ordered chapters, each presenting one or more important philosophers (Kant gets two) and their most famous ideas

One lesson
Aristotle believed that heavier materials fall faster than lighter ones and the ones who came after him simply believed him. Such "truth by authority" — trusting someone's ideas only because of his status in society — is bad for intellectual progress.

Reading Recommendation / Who should read this?
I truly enjoyed listening to this. Very suitable for an audiobook format. It gave me a good overview and of the most important ideas in philosophy. For someone who didn't study the field but is very interested in it, it's the perfect introduction. Most of the philosophers I was already familiar with, but the details of their contributions I did not know. Overall I rate this a 7 out of 10 (⭑⭑⭑⭑) on my rating scale, mostly for its structure and how the content is presented. However, it is and can only be an introduction. Who wants to learn more has to consult the originals.

#27 Xcode Treasures | Book Review

XCode TreasuresXCode Treasures by Chris Adamson
My rating: 3 of 5 stars

Context & Why I read this book
I am a software engineer with focus on Swift and Apple platforms. Using Xcode is my daily bread. I was hoping to learn some more tips and tricks to master my main IDE.

What is the book about as a whole?
The book takes you through all major parts of working with Xcode, the IDE for developing software on Apple platforms. It tackles basics like project setup, working with storyboard, and editing source code but also explores some more intermediate topics like improving performance, security, and extending Xcode.

The book's structure
The book is divided into 12 chapters and comes with many screenshots and code samples:
1. Projects
2. Storyboards: Appearance
3. Storyboards: Behavior
4. Editing Source Code
5. Building Projects
6. Debugging Code
7. Improving Performance
8. Automated Testing
9. Security
10. Source Control Management
11. Platform Specifics
12. Extending Xcode

One lesson
One thing I learned about was were the advanced breakpoint actions Xcode offers: logging messages, playing sounds, executing debugger commands, and the "expr" LLDB command which lets you change the values of variables at run-time, something that can come in handy once in a while.

Reading Recommendation / Who should read this?
(This recommendation is only targeted at developers on Apple platforms) I don't think that you necessarily need to read it (especially if you have 3+ years of experience with Xcode). I learned a couple of new things but in the end, the book was lacking depth. Also, quite naturally for a book like this, newer topics are missing (like working with SwiftUI previews or using the latest Xcode features from the last 2-3 years). Considering that there are so many valuable other books you can read to improve your craft overall this is a 5 out of 10 (⭑⭑⭑) for me.

#26 We: Understanding the Psychology of Romantic Love | Book Review

We: Understanding the Psychology of Romantic LoveWe: Understanding the Psychology of Romantic Love by Robert A. Johnson
My rating: 4 of 5 stars

Context & Why I read this book
2021 was the year I moved together with my girlfriend and I didn't want to leave anything to chance. Love is a topic everyone is familiar with, but few ever truly understand. On this topic, I have already read The Psychology of Romantic Love, but I felt that there was more to it; more to discover; more to get clarity about.

What is the book about as a whole?
Johnson takes the myth of Tristan and Iseult (the apparently oldest account of "romantic love" there is) as a device for explaining and demonstrating the distinction between true love and romantic love (story-book" love). For that, he introduces and uses the Jungian concept of "Anima", a part of the psyche that used to be called "soul".

The book's structure
The book is divided into 4 main parts and a conclusion. Each part leads with an excerpt of the myth and then contains 3-5 chapters elaborating on it.

One lesson
There is a beautiful passage in chapter 14 that contains one of the key messages from the book: One of the great paradoxes in romantic love is that it never produces a human relationship as long as it stays romantic. It produces drama, daring adventures, wondrous, intense love scenes, jealousies, and betrayals; but people never seem to settle into relations with each other as flesh-and-blood human beings until they are out of the romantic love stage until they love each other instead of being "in love". This single insight alone can save you from wasting countless years or even your whole life.

Reading Recommendation / Who should read this?
I highly enjoyed reading this beautifully written book (reading it on the beach during my last summer vacation made it even more enjoyable). I would generally recommend it to anyone who at some point wants to be in and maintain a monogamic relationship for life. That probably includes the majority of humanity. 8 out of 10 (⭑⭑⭑⭑) for me. The only reason I did not rate it a 9 is that due to the myth chosen by the author, the book is more approachable for men than for women (since the latter have to do some transfer and mapping).

#25 A Voice from the Attic | Book Review

A Voice from the Attic: Essays on the Art of ReadingA Voice from the Attic: Essays on the Art of Reading by Robertson Davies
My rating: 3 of 5 stars

Context & Why I read this book
Reading more does not equal reading better, but this year I challenge myself to read 52 books in order to become a better reader. Some of the books I selected for this are on the process of reading itself. This is also the case for "A Voice from the Attic". I did not know exactly what this book would entail, but the subtitle "Essays on the Art of Reading" was catchy enough for me to include it.

What is the book about as a whole?
This book is multiple things
1. a plea for the "clerisy" to return and form a union once again.
2. a collection of book reviews and recommendations, sorted into categories like self-help, history, drama, humor, and even pornography
3. an attempt to answer several questions like what reading is, why you should read, what a good book is, how to categorize books etc.
4. An interesting and worthwhile collection of related essays on the art of reading

The book's structure
The book is divided in 8 chapters:
I. A Call to the Clerisy
II. Enjoying and Enduring
III. Ovid Is Not Their Master
IV. From the Well of the Past
V. Making the Best of Second Best
VI. The Hue and Cry after a Good Laugh
VII. In Pursuit of Pyrography
VIII. Spelunking on Parnassus

One lesson
Davies sums up all self-help books with the Latin phrase "Vol enter ducti, nolenterm trahit" meaning "success will come to those who want it most, and will avoid those who, for whatever reason, stand in their own way."

Reading Recommendation / Who should read this?
For me and my current attempt to become a better reader, this was an interesting little detour. However, even if it is a very good book in itself, I don't think this is a book for "everyone"; instead it is only intended for the clerisy (people, who "read for pleasure, but not for idleness; who read for pastime but not to kill time; who love books, but do not live by books"). Since my ratings also reflect general reading recommendations, I rate this niche-focused book here only a 6 out of 10 (⭑⭑⭑) — if you count yourself to the celerity (which if you are reading this on Goodreads you quite likely do), it could well be a 7 or even 8 for you.

#24 Permanent Weight Control | Book Review

Permanent Weight ControlPermanent Weight Control by Michael J. Mahoney
My rating: 3 of 5 stars

Context & Why I read this book
Well, I am currently overweight and wanted to procrastinate doing anything about it by reading another book on how to do so. Jokes aside, I am currently really struggling with weight control and it seems no matter what I try I slightly gain some ½ kg per month for over a year now. Mahoney is one of my favorite and most trusted authors, and I wanted to avoid hyped diet books on the topic; that is why I chose this book from 1976 instead of the many alternatives that present themselves.

What is the book about as a whole?
The book aims to provide a system for losing pounds and keeping them off forever — a very ambitious goal. For this, Mahoney presents the best scientific evidence from that time (1976) for doing so. The book is very practical in that it is easily understandable, includes many assignments and exercises, and takes you by the hand in a step-by-step manner.

The book's structure
The book is divided into 12 chapters:
1. This Can Be the Last Reducing Program of Your Life
2. Reduction Readiness
3. Thick and Thin: What Makes the Difference?
4. Getting in Focus: The Culprits Are Patterns, Not Pounds
5. The Elements of Successful Self-Control
6. Cognitive Ecology: Cleaning Up What You Say to Yourself
7. Engineering a Slim Environment
8. Reducing with Reason: The Personalised Diet
9. Is Your Eating Style a Problem?
10. You Don't have to Be Radical to Be an Activist
11. Emotional Eating: Relax — You're not Hungry
12. Troubleshooting and Maintenance

One lesson
I am a professional caffeine -> source code converter (I drink a lot of coffee at work). Therefore, one personally relevant piece of information for me was that there was evidence at the time that caffeine may reduce blood sugar levels, giving rise to the sensation of hunger. I'll need to follow up on this and research if this has been refuted in the last 50 years.

Reading Recommendation / Who should read this?
Overall I rate this a 7 out of 10 (⭑⭑⭑⭑): it's a good read, despite minor weaknesses; and I generally recommend it to people who struggle with weight control. Although I didn't translate it into practice yet, the presented system seems very promising and I will make it a top priority to follow it in 2022. One year from now I shall come back and re-rate this based on my success or failure of applying it.

#23 Growth Through Reason | Book Review

Growth Through ReasonGrowth Through Reason by Albert Ellis
My rating: 2 of 5 stars

Growth Through Reason

Context & Why I read this book
I am exploring "rationality" this year and already have read (and really liked) Ellis' A New Guide to Rational Living. Furthermore, everything with the term "growth" in it captures my attention since personal growth is at the heart of my personal mission statement.

What is the book about as a whole?
The book is a collection of clinical sessions conducted by several psychiatrists. Among the problems discussed in these sessions are masochism, depression, homosexuality, sex life and marriage, religion, phobic reaction, all loosely connected by the fact that RET (Rational-Emotive Therapy) was chosen as a form of therapy. The sessions are all interluded with commentary by Ellis on why something was done a certain way, why it worked, and how it could have been done even better.

The book's structure
The book is divided into 8 chapters:
1. Introduction
2. The Case of the Black and Silver Masochist
3. Rational-Emotive Therapy with a Culturally Deprived Teen-Ager
4. A Young Male Who Is Afraid of Becoming a fixed Homosexual
5. A Young Woman with Feelings of Depression
6. A Husband and Wife Who Have Not had Intercourse During Thirteen Years of Marriage
7. A Relapsed Client with Severe Phobic Reactions
8. A Twenty-Three-Year-Old Girl, Guilty about Not Following her Parents' Rules

One lesson
I quote a passage from the book: "A human being is an ongoing process and is constantly changing. It is therefore inaccurate to measure him on the basis of any of his past or present behavior—which merely shows, at most, what he has done up to now but doesn't necessarily show what he may do from now on."

Reading Recommendation / Who should read this?
While there are some interesting parts of the book I would rather recommend you read Ellis' more prominent books like the superb A New Guide to Rational Living (unless you are a psychologist yourself and can gain more from all these recorded interviews). This one here deserves only a 3 out of 10 (⭑⭑⭑) on my personal scale.

#22 Algorithms to Live By | Audiobook Review

Algorithms to Live By: The Computer Science of Human DecisionsAlgorithms to Live By: The Computer Science of Human Decisions by Brian Christian
My rating: 3 of 5 stars

Context & Why I read this book
2021 is my year of rationality and the quite popular "Algorithms to Live By" seemed to be a natural fit. However, since I was skeptical I listened to this as an audiobook during some casual runs through the parks of Munich, instead of reading it.

What is the book about as a whole?
It tries to show, how algorithms for caching, sorting, stopping, ... can help solve problems in everyday life.

The book's structure
11 chapters, each targeting a special class of algorithms:
1. Optimal Stopping — When to Stop Looking
2. Explore/Exploit — The Latest vs. The Greatest
3. Sorting — Making Order
4. Caching — Forget About it
5. Scheduling — First Things First
6. Byes's Rule — Predictign the Future
7. Overfitting — When to Think Less
8. Relaxation — Let Is Slide
9. Randomness — When to Leave It to Chance
10. Networking — How We Connect
11. Game Theory — The Minds of Others

One lesson
I heard this a couple of months ago and unfortunately lost my note on it (thank you Audible); so the only lesson I am taking with me for now, is that it contains some very interesting tidbits on exploring/exploit and sorting and that I want to reread this in physical book format.

Reading Recommendation / Who should read this?
Although it has some hilarious examples for the application of the algorithms that can and should not be taken seriously (like using an algorithm to find a soulmate) it contains many worthwhile and insightful bits of information; both for people unaware of algorithms (as an introduction) as well as those who studied something like computer science (as a way of transferring their knowledge to other domains). The book is good. I rate it 6 out of 10 (⭑⭑⭑). I would not recommend the audiobook version, though, and I will probably reread it in book form. The reason is that there are too many interesting references that I wanted to look up. For such a book I would highly prefer a paper or eBook version.
