Books That Make You Smarter – 38 Best Reads for 2026

Looking for the best books to make you smarter? Whether you’re after fiction or non-fiction, the right books can boost your IQ and sharpen your thinking. Reading daily, from thrillers to psychology, really helps you think faster and smarter.

Books aren’t just for fun—they can help you figure out life better. When I started reading books like Make It Stick and Procrastination, I noticed my focus improved. It’s not magic, just smart science made simple.

Have you ever wondered how some people seem to make better decisions? Books on cognitive psychology and human history help you see why. For instance, A Brief History of Time gave me a new way to look at the universe—and my place in it.

Some novels, even thrillers or romance, stretch your mind differently. They teach you to see things from other angles. I once read a story that changed how I judged a situation at work—it stuck with me. 

And don’t worry if you prefer novels or poetry. Fiction is great for learning how to read between the lines and understand people better. I remember finishing a novel and suddenly catching a small but clever clue about human nature I’d missed before. Cool, right?

Some notable books that help boost intelligence include Make It Stick, Uncommon Sense Teaching, and Jared Diamond’s Guns, Germs, and Steel. These easy reads, packed with facts and ideas, make your brain work harder without feeling like school.

Reading more will make you smarter and wiser, plain and simple. It’s like training your brain—just a little each day—and you’re thinking clearly and faster before you know it. So, what are you waiting for? Pick up a book and get smarter today.

1. Cosmos by Carl Sagan

Carl Sagan's "Cosmos" tells the history of the cosmos for 15 billion years, which is incomparable to anything. 

This book shows how extensive and profound Carl's interests are and draws readers to a fascinating world. 

Although this book is mainly about how science develops in our society, it deals with topics such as history, philosophy, religion, and culture. 

The book is simple and understandable to those without a scientific background.

What a privilege and joy it was to have read this book. I made my way through it rather slowly because it was so packed full of historical anecdotes, scientific findings, and thought-provoking insights that I needed a break every chapter or so to let ideas mentally sink in. In 13 chapters, Dr. Sagan gives us a glimpse into all scales of space and time.—Read More—Nichanan Kesonpat

2. This Will Make You Smarter by John Brockman

This Will Make You Smarter: This is the question John Brockman asked the most influential thinker in the world. Their visionary answers come from psychology, philosophy, economics, physics, sociology, and other fields.

Amazing and inspiring, these insights will radically change the way you see yourself and the world.

Brockman's books extracted from Edge.org are really hubs that, through their spokes (the essays they group together under one question), allow the reader to reach out and grab, experience, and explore the often difficult-to-follow contemporary thought in many scientific disciplines. Otherwise, we could define them as toolkits from which to extract the necessary tool that helps us to better understand our ever-changing world.—Read More—Magazine Sabina

3. Train Your Brain by Dr. Ryuta Kawashima

Train Your Brain: This essay promises to stimulate your brain to prevent its aging and loss of ability. It contains a series of spreadsheets that you exercise every day to improve your brainpower. Japanese bestseller is a practical and fascinating way to stimulate your mind.

I've been doing this daily. I'm up to about day 30. Of course, I can't tell if it's working or not, but I do enjoy challenging myself, and I feel as though this book is doing the trick... I do not write IN THE BOOK... I write on a separate tablet so I can use the book over and over again.—Read More—Mrs. Tami M. Stover

4. Essentialism by Greg McKeown

Essentialism: You can't be wrong here. Essentialism advocates eliminating the unnecessary pursuit of important things. 

McKeown combines principles of personal leadership, insights into employee engagement, strategies for business success, and suggestions for better decision-making and smart living. This is one of the few books I want to reread, even before I finish the last chapter.

My title sounds like I'm lying - who would read a book that many times? But honestly, this has become my go-to book whenever I feel overwhelmed with life. It helps me simplify, but so much more than just that. It helps me analyze my current projects and focus on the 2-3 that will —Read More—Destiny Yarbro

5. The Willpower Instinct by Kelly McGonigal, Ph.D

The Willpower Instinct: I'm fascinated by the connection between good habits and willpower. In the willpower instinct, McGonagall (Kelly is Jane's twin sister and has three TED talks on Game Theory) guides willpower and provides life-changing prescriptive advice and supplementary exercises to help us cope with more difficult challenges such as weight loss, procrastination, happiness, and parenting.

A lot of research on willpower and self-control is conducted by research psychologist Roy Baumeister. The willpower of his book is a good companion for McGonagall, especially if you are an evil experiment on unsuspecting college students.

Out of all the books on how to build self-control, the one I recommend most is The Willpower Instinct by Kelly McGonigal. There are two reasons why:

First, this book is optimistic. After reading what some people have to say about willpower, you might be left with the impression that if willpower is a limited resource, and you deplete it, especially if you have lots of stress in your life, you’re out of luck. —Read More—Tom Venuto

6. The Lean Startup by Eric Ries

The Lean Startup: The premise for this bestseller to stand out can be summed up in this quote from Lean Startups: "Most startups fail. But many of these failures can be prevented. " Ries shows both the dangers of releasing untested products and the more pedantic process of releasing "least viable products" 

and then make incremental changes based on customer feedback. Rice combines his entrepreneurial experience with case studies of other start-ups (mainly technology-based) to provide a very readable recipe for building entrepreneurial success in an orderly manner, one "fulcrum" at a time

This book focuses on giving an overview of Lean methods and convincing you why you should use them. It uses a lot of examples, mainly from startups. Some of the best examples come from the author's own experience, and his company continues to do well. However, other examples haven't aged well.—Read More—B. Hill

7. Think and Grow Rich by Napoleon Hill

Think and Grow Rich, because it's about being smarter, not about making money, but more about understanding the basic elements that make people successful in anything.

Deep in the rabbit hole, we need to know what drives the world, what creates change, and what drives us. As far as it is concerned, its value is immeasurable.

If you want to learn how to act to change the world, read Think and Grow Rich."

In your journey for success, and I've read over 150 books on business and personal development, this is the godfather. The only true place to start. But be wary, because this book requests you physically do things outside of reading, such as writing your daily goals, writing your 6 steps, and reciting them daily. —Read More—Nick W

8. Last Chance to See by Douglas Adams and Mark Carwardine

Last Chance to See: From the first time someone died from eating the wrong berry to seeing a mad dog's instinctive response on the street, our ability to recognize and understand other creatures is crucial to our survival. 

In a large part of the modern world, naturalistic intelligence is seriously inadequate, and we are isolated from hunting, farming, and wilderness survival, which were once essential. 

Adams and Cavutin's books focus on endangered species, and it's a good place to start your naturalistic re-education.

I normally wouldn't review a twenty-five-year-old book, but since "Last Chance to See" is just as relevant today as it was in 1990, some words are warranted. Also, being an author myself, who writes similar humor-infused, ecologically-minded travel books, I must say that from now on Douglas Adams will be the writer I most aspire to emulate.—Read More—Marty Essen

9. The Stranger by Albert Camus

The Stranger: On the surface, Camus's classic is a straightforward story of a man who committed a terrible crime and paid the price. In essence, it's fighting against the basic problems that we have. 

There's no better way to improve your survival IQ than to read it twice. Maybe, think of Camus' absurd view. 

Our existence is one of the basic facts of our lives, but in many ways, it is a mystery. After reading this novel, think about it; whether you realize it or not, you will become smarter.

The first novel I’ve read in ages; I was exposed to Camus by a Goodreads reviewer. Much later, a bracing audio series by The Great Courses and Robert Solomon arrested my interest. Without both, I’d not have liked the book as much.—Read More—Brett Williams

10. Hamlet by William Shakespeare

Hamlet: People with linguistic wisdom find that language is a flexible tool that can be used to accomplish anything. 

Considering that a large part of the vocabulary you use every day was invented by Shakespeare, he has one of the highest linguistic intelligences in history.

The challenge here is to read his plays in 16th-century English without reference materials and see how much you can understand. 

Then you can stop reading. You may end up having to look up something (some of Shakespeare's references are very topical), but forcing yourself to think about what he said is a good practice.

Hamlet itself is a fantastic read, so I would definitely recommend it (even if you're not a Shakespeare fan, which I'm not).

On a side note, I would also recommend reading Rosencrantz and Guildenstern Are Dead by Tom Stoppard to gain an entirely new and humorous perspective on Hamlet. Or you may even want to read it beforehand to help you get more enthusiastic about having to read Shakespeare.—Read More—August

11. The Almanack of Naval Ravikant by Eric Jorgenson

The Almanack of Naval Ravikant: The author of The Almanack of Naval Ravikant is known for a large number of golden lines. He is an entrepreneur and angel investor, and regularly shares his life wisdom on social networking sites and blogs.

What Naval said was easy to understand, concise, and sharp. He seems to be in control of everything. This book is a selection of all his golden lines. 

I've picked out a few quotes that give a glimpse of the book's style:

• "Memory and identity are the burdens of the past that keep us from being free to live in the present."
• "Desire is a contract you make with yourself, and you're not going to be happy until you get what you want."
• "The three elements of life are wealth, health, and happiness. We pursue them in order, but their importance is reversed."

12. The Psychology of Money by Morgan Hauser

The Psychology of Money: How many people do you know who are very smart in their careers but mess up financially? Maybe you are one of them.

Earning, storing, and increasing wealth all require emotional intelligence and self-control. Even very smart people can't do it all.

The book mentions that investing is not finance but a field that studies how people treat money. Behavior is hard to teach, even to smart people. Behavior cannot be guided by formulas or tables. 

Behavior is innate, varies from person to person, and is difficult to measure. Over time, it has become easier for people to deny its existence, especially when describing themselves. Managing money has nothing to do with how much you know; it's only about what you do.

The Psychology of Money is by Morgan Housel. In his book, he points out the psychological pitfalls we are prone to encounter when trying to invest. However, Morgan doesn't tell you directly what to do and doesn't give direct advice, which is the hallmark of this book.

13. Rebuilding

Rebuilding: When your relationships (especially relationships) take a hit, no amount of wealth or career success can make up for it. 

It's interesting that we have a lot of formal school training and in the workplace, but we're rarely told how to get along with other people, and yet, getting along with people is a very important point.

Maybe relationships are not something you can learn in school, but there are definitely books that will help you. "Attached," by Amir Levine and Rachel Heller, is an analysis of human relationships, especially romantic relationships.

This book discusses three models of romantic relationships that you can learn more about by reading the entire book:

Anxious: Usually clinging, interdependent, fearful of loneliness

This book provides practical information that can help readers understand their own relationship patterns and the pros and cons of having healthier relationships, or help readers make more informed decisions in relationships.

14. Letting Go by Dr. David Hawkins

Letting Go: How can our emotions prevent us from living a better life? A wise man understands how one should live.

Feeling happy and living a happier life requires you to recognize and learn to let go of everything that is preventing you from living a happy life. When you don't have a heavy burden, you can run toward happiness more freely.

Dealing with emotional crises can lead to greater wisdom and can benefit you throughout your life. The fear of life is actually the fear of emotions. What we fear is not the fact, but how we feel about it. Once we get control of our feelings, our fear of life decreases.

As the title says, Letting Go is about teaching readers how to "let go," such as learning to let yourself feel certain emotions rather than trying to suppress them and keep them trapped in your body forever.

Whether you're learning how to deal with past trauma and negative thoughts or defining your present experiences, you'll find techniques for dealing with emotions and ultimately getting rid of them. The book also talks about a lot of examples that can make you smarter in practice.

15. When I Stop Talking, You'll Know I'm Dead by Jerry Weintraub

When I Stop Talking, You'll Know I'm Dead: Street smarts are underrated. I define this little cleverness as the ability to get what you want. Many people with high IQs don't have much success in life because they're too conformist and don't know certain side doors to look for opportunities to get in.

For example, most people won't apply for certain jobs if they don't meet the criteria. They can take inspiration from Jerry Weintraub's book:

When the other person says no, you pretend not to hear. You look puzzled, and you say, "Huh?" You keep going - it sounds like a cliché, but it just works. Successful people are the ones who keep going after everyone else has left. 

This persistence is more important than governance, lineage, or connections. Be stubborn! Just keep hitting that door until you hit it! I got nothing on my first, second, or even third try—good news usually comes late, mostly after everyone else has left.

The book covers the author's journey to finding his first job, from not getting hired to becoming a gold manager, and his story of raising $1 million in 24 hours.

How did he do that? He never gives up a thing in a failure situation. He can always think of an angle to work hard to get what he wants. He thinks creatively and proposes solutions when there is no solution. This is a fascinating book.

16. Discourse on Method and Meditations on First Philosophy

Discourse on Method and Meditations on First Philosophy by René Descartes. 

I read this book in my freshman year. At that time, I was bored and pulled the thinnest book from the shelf. After reading it, I suddenly felt that the whole person became smarter (mainly because of the greater room for intellectual improvement). 

It is Descartes' first work and a very young book. It is surprisingly short, with only 60 pages in the main body, but it has deeply shaken the entire history of Western philosophy. It is a good choice to enter the history of philosophy from it. The content and the original title of the book have already been stated clearly, 

"Talk about the correct use of my own reason to seek the truth in various disciplines", to make it clear that as long as I use reason, there is nothing I can't understand. Many famous sayings in the book are already well-known, such as conscience is the most evenly distributed thing in the world, I think, therefore I am, and so on. 

Descartes’ thinking was clear, and he applied the rules found in logic, geometry, and algebra to his thoughts (don’t forget, he is also an important mathematician). This method later made me wonder when I didn’t understand the problem, and I always benefited from it.

17. The Eighteenth Brumaire of Louis Bonaparte

The Eighteenth Brumaire of Louis Bonaparte by Karl Marx. 

Western pamphlet writing was originally used to express opinions on current affairs. This writing method makes it difficult for pamphlets to escape the fate of rapid decay, but Marx’s book has undoubtedly withstood the test of time. 

A large number of characters who have written "destroyed their fame", and those famous celebrities can only be known with the help of annotations. In the book, what Marx is dissatisfied with is that many people clearly think that Louis Bonaparte is ugly, but it is easy for readers to regard him as a hero who changes the situation. 

What he had to do was demonstrate how the interests of the various groups at the time were divided and changed so that Louis Bonaparte and his mediocre group could succeed in a coup. It is not interesting to read this pamphlet in the Trump farce era, but few scholars now can write like this. There is no "data", no "investigation" in the book; it is too thin, too ambitious, and too interesting. 

The advantage of Marx is also that he is very good at writing. Levi Strauss once said that he would read dozens of pages of "The Eighteenth of Fog Moon" every time before writing a book to find a sense of expression.

18. Civilization and Its Discontents

"Civilization and Its Discontents" by Sigmund Freud. 

He is a very good person who asks questions. This book asks, Why are people hostile to civilization? Why do the more civilized humans feel more pain? 

Why is it that people "cannot bear the massive setbacks that society imposes on them when satisfying his cultural ideals"? 

He also believes that politics is completely powerless for human happiness: "Not everyone is worthy of love." 

The book touches on most of the issues that contemporary thinkers are concerned about and also discusses the status of women in civilization, making it a very good basic discussion text in all aspects.

19. The Use and Abuse of History

Among the "Pocket Classics" is Friedrich Nietzsche's "The Use and Abuse of History", which is also a frequently read pamphlet. Nietzsche is a master in this area. 

Reading Nietzsche is the most healing time (his autobiographical catalog is this style: Why am I so smart, why do I write such a good book...). The full text of this book is 100 pages. 

The original title is "The Advantages and Disadvantages of History", and the English version is "The Use and Abuse of History." 

Contrary to what many people think, Nietzsche is not very easy to read, in my opinion. Many texts are "hyperlinked" together. Concepts are often wrapped in tortuous prose, which can be called a kind of stem-like writing. 

The point of view in the book is simple in the end: history is for strong people to read; history is necessary for individuals or nations, but if the "sense of history" reaches a certain level, it will eventually harm and ultimately destroy a person or nation. 

Even the life of the cultural system. However, we must pay attention to "Nietzsche's use and abuse" when reading him.

20. Freud And The Non-European

"Freud And The Non-European" by Edward W. Said 

The booklet I read recently is the last book of the famous postcolonial thinker Edward Said during his lifetime. It is also a collection of lectures, so it is easy to read. The discussion is on Freud's last book, "Moses and Monotheism." 

In the era of the Nazis, Freud wrote this book, and he actually proved that Moses was an Egyptian nobleman. He chose the Jewish nation and taught them monotheism from Egypt (this book itself is as wonderful as a detective novel). 

This is undoubtedly a Jew "anti-Semitic" book, a book "handing a knife" to the Nazis. Palestinian Christian immigrant Said interpreted this book in the post-colonial era and discussed the hot issues of identity politics. 

It is very interesting. The book specifically mentions that archaeology is the privileged Israeli science par excellence, and the reasons are self-explanatory. Palestinian archaeology can be said to be the legacy of Freud's book.

21. The Uprising: On Poetry and Finance

"The Uprising: On Poetry and Finance" by Franco "Bifo" Berardi. 

How can poetry and finance go hand in hand? Poetry is a "non-interchangeable language" and cannot be simplified to circulate everywhere like information or currency. It is the opposite of finance in all respects. 

The financial crisis is actually a crisis of social imagination, and a new political weapon of language poetry is needed to solve it. 

This book has a weird point of view, but it is witty to read, and I want to fall into the world. In addition, the format is gratifying and suitable for reading.

22. Pathologie de la vie sociale

"Pathologie de la vie sociale" by Honoré De Balzac 

The three theories of "Fair and Elegant Life", "On Gait", and "Modern Doping Theory" were collected in the "Complete Works of Balzac", which are actually pamphlets. 

These three articles have been compiled in a single edition, but they are said to have been translated. Generally, let's use this as the cover. 

"On Modern Stimulants" has also been published in a single book, and it has been made into a 32-volume book with large characters and one-sided printing (!), which is really unnecessary. 

Balzac’s three theories are very funny, so funny that the translator is very confused about why he is interested in them (reading Benjamin’s "Paris, the Capital of the 19th Century", you can find the beauty of Balzac’s three theories. Up). 

After reading it, I discovered that later generations of books, such as "Style" and "Snobbery," are not as interesting as this. 

For example, Balzac's comment on advertising: "Modern powerful advertisements discount things that cannot be found in the Bank of France, namely: all the thoughts of the most stupid and stupid public in the world, all the credulity of the least credulous age, the most selfish All the sympathy in the heart of the world." 

He went to the streets to observe people's walking movements and concluded, "Civilization corrupts everything! Tamper with everything, even movements! Should I go on a round-the-world trip to observe the gait of the savages?" 

He talked about the tool man: "The tool man is a kind of social zero." He said that he was a "human candle" and kept working to burn himself. 

The funniest thing is the translation and annotations made by Balzac scholars, who constantly slapped him. For example, he said that he met the composer Verdi, who greeted him. The scholar said that Verdi was not in Paris at all, and it is unlikely to known an author who was not well-known at the time...

23. On Translating Homer

"On Translating Homer" by Matthew Arnold 

74 pages. Arnold, the pride of British literary circles, is too strong! He summarized the four characteristics of Homer's epic: 

1. Swiftness; 
2. Easy and direct language expression; 
3. Easy and direct thinking; 
4. Noble. 

I also commented on each of the interpreters at the time one by one, and the conclusion was: "I am not targeting you, I mean everyone here is rubbish."... 

Well, the original saying goes like this: 

"If the poets of a country are like this, then they are all You have to be thrown into the fire for purification seven or eight times before you can hope to translate Homer." 

This classic booklet was published by the University Press, and it was silent, which is really a pity.

24. The Order of Time

"The Order of Time" by Carlo Rovelli 

Because of my personal interest, I have read a lot of books about time. This type of book can easily be written into a huge chapter. Although this general undergraduate book has more than 180 pages and is hard-covered, the number of words is not large. 

The most powerful is his writing method, which is rich in content, easy to understand, and full of a humanistic atmosphere. 

It is quoted by the philosophers of the former Socratic era. To "Mahabharata", "Bible·Ecclesiastes", to "Alice in Wonderland", Heidegger. There is only one formula in the book, the second law of thermodynamics.

25. The Perks of Being a Wallflower

The Perks of Being a Wallflower by Stephen Chbosky. 

The first English book I finished reading was on the Kindle. As a junior in high school, Charlie presented his thoughts on his old life and his anxiety about his new life in the form of letters. Instead of pretending to be deep, he described complicated or simple family, friends, and teacher-student relationships in a shallow style, and Sensitive topics such as drugs, violence, and homosexuality. 

Because each letter is a basic unit, the plot is relatively trivial, which makes people lack the urge to read it all at once; the differences in the campus environment also don't have enough sense of substitution. However, the state of mind that Charlie expressed during the first year of enrollment is similar to his. 

The secret love and close relationship with Sam are also very real, but I think the friendship is more fragile. Although there is always a depressive atmosphere in the novel, the author still gives the story a good ending: "Things are good with me, and even when they're not, they will be soon enough." But he doesn't like Charlie's mental state. I feel that this is not helpful for character creation.

26. Thinking, Fast and Slow by Daniel Kahneman

Struggling to understand your thinking patterns? This book shows how your brain uses two systems—one fast, one slow—and how to catch mental shortcuts that mess with your decisions, helping you become smarter and more aware.

• Ever bought something stupid because it “felt right”? Yeah, me too. This book explains why we make dumb calls without realizing it. Your brain’s on autopilot more than you think.
• Kahneman breaks thinking into two modes: fast (instinctive) and slow (deliberate). Realizing which one’s driving can help you avoid traps, especially when it comes to money, time, or arguments.
• Want to increase your intelligence? Pause before reacting. That’s it. Thinking slower (literally) can improve judgment, especially in high-stakes stuff. Feels strange, but works.
• I tried forcing myself to use System 2 more during tough conversations. My stress dropped. I got clearer. And fewer “Ugh, why did I say that?” moments.
• This isn’t an easy read, but it’s one of the best books that will make you smarter. You don’t need to memorize terms—just pay attention to how your mind plays tricks.
• The author doesn’t sugarcoat human error, and you’ll spot your flaws. But knowing them gives you power. Want to stop getting fooled by your brain? Start here.

27. Death Notice by Zhou Haohui

China's highest IQ social crime novel, let all self-think high IQ readers applaud the case! Anyone who receives the "death notice" will be brutally killed by the mysterious killer according to the date of the notice. 

Even if the victims report to the police, the police use the maximum police force to lay a net around the world and protect the victims closely. The mysterious killer can still kill the other party's hand without any effort under a heavy ambush.

As a result of the first round of confrontation, many years of secrets have gradually revealed the truth. The weakness of human nature is struggling in an extreme environment. 

The shocking answers let the members of the ad hoc group can't bear to see the new generation of death adjudicators, young Eumenides, have just begun the decisive battle with Luo Fei! 

Promising review:

An exciting book that you'll find very hard to put down. Full of teams and turns, and I look forward to reading more from this author as (hopefully) more of his books get translated in time. Well worth the purchase. A gripping read from start to finish.—Read More—The Night Gardener

This is a "big book" about the evolution of human society (or complex systems in a more general sense). For those readers who are not afraid of "mental gymnastics", it is bound to open a book. 

Promising review: 

What a book! I will be thinking about the concepts and ideas presented in this book for a long, long time. Kelly is a little more at home writing magazine articles, and sometimes the book lacks a coherent thesis, but that is more than made up for with wonderful prose, and unbridled excitement for his subject.—Read More—Jeremy Foote

29. And Then There Were None by Agatha Christie

Ten strangers were invited by the rich Mr. Owen to a private villa on the Indian Island. After dinner, a mysterious voice revealed the terrible secrets hidden in people's hearts. 

On that night, young Mr. Marston died strangely. The old nursery rhyme was like a curse. It seemed that there was a pair of mysterious glasses watching the game of death all the time. 

The visitors were like the disappearing little Indian porcelain one after another. This is the most famous work of detective queen Agatha Christie, which has been translated into 40 languages and adapted into movies, TV plays, stage plays, radio plays, video games, etc. 

Promising review:

Having read everything she had written, I've always debated as to which of Agatha Christie's works tops my list. For a while, it was "ABC Murders". But, having re-read "And Then There Were None," I came to the conclusion that there's simply nothing else like it, and it tops my list.—Read More—Andrew Beyzman

30. Spectrum of Consciousness by Ken Wilber

The Spectrum of Consciousness is the first book written by Ken Wilbur, a great master of transpersonal psychology. He compares the essence of human consciousness to a rainbow spectrum, from shadow to self, then to mind and soul, and finally to the perfection of spirituality.

Ken Wilbur integrates psychology, psychotherapy, mysticism, and spiritual cultivation of Eastern and Western religions with his amazing inductive research ability. 

He also integrates many fields such as philosophy, sociology, transpersonal psychology, anthropology, mythology, economics, biology, physics, etc., forming the "grand unified field theory" of consciousness and starting a revolution in transpersonal psychology. 

Promising review:

“Spectrum has intrinsically different characteristics—different needs, different symbols, different modes of awareness, different motivations, different compensations, and so on. When a particular level is rendered unconscious, so are the major features of the characteristics of that level. Thus, the unconscious is stratified, and for the very same reasons that the Spectrum itself is stratified.”—Read More—Todd M Runyon

31. Finnegans Wake by James Joyce, Ireland

This book describes a night dream, with a "labyrinth" literary structure, full of stream of consciousness. Joyce even invented a unique "dream language" in the history of the world's languages. 

One of the most famous words in the whole book is Joyce's 100-letter word "lightning strike", which simulates the continuous rumble of thunder. What is more amazing is that the first sentence of the novel is "written on the last page", while the last sentence is "written on the first page".

Promising review: 

I don't think my life is long enough to give this book the close reading it deserves, but I'm enjoying the challenge of seeing how much I can understand. I would recommend it to obsessive-compulsive freaks with a sense of humor.—Read More—Kristin Ohman

33. Engines of Logic by Martin Davis

This book can be said to be the originator of computer thought. It introduces the basic concepts behind modern computers and the people who developed these concepts. 

It describes the lives and work of geniuses such as Leibniz, Bull, Freig, Cantor, Hilbert, Godel, and Turing, and describes how mathematicians have put forward the ideas behind the achievements long before they are put into application. 

Promising review: 

Although other logicians are well covered, the emphasis is on Alan Turing. There is a wonderfully clear and simple presentation of the unsolvability of Hilbert's Entscheidungsproblem using Turing machines. I recommend this book to mathematicians & non-mathematicians alike.—Read More—L. Shalla

34. Strategic Thinking: strategic competition in business, politics, and everyday life by Avinash K. Dixit

The science of strategic thinking is called game theory. "Strategic Thinking: Strategic Competition in Business, Politics, and Daily Life" is a classic book on game theory co-authored by Yale University Professor Neil Boff and Princeton University Professor Dixit. 

When they started writing, few people knew game theory. Nowadays, game theory has gradually become a popular course in Colleges and business schools. This book is about the art of knowing how your opponent intends to beat you and then winning. 

How to win a tennis match, how the minority can beat the majority, why you should "love" your most hated opponent, and so on, are all discussed. This is an emerging strategy in science, which consists of some simple basic principles. 

Promising review: 

Thinking Strategically is one of the first books I ever read on strategy. Since I read it it has changed my perspective and way of thinking and analyzing all sorts of problems from business to personal life. The book, in a sense, has become a manual of problem assessment in my life. I have used its concepts in situations where I have to predict rivals' moves in business, work, and personal life.—Read More—Anthony Tate.

35. A Brief History of Time by Stephen Hawking

Confused by black holes or time travel? Hawking explains tough science in simple terms so you can understand how the universe works—and feel smarter while you're at it.

• Don’t worry—this isn’t a math book. I failed physics in school, and I still understood it (well, most of it). Hawking keeps the big stuff simple.
• He covers everything from black holes to the shape of time—yes, that’s a thing. It's one of those books that expands your brain without frying it.
• The tone’s a bit dry, but the ideas? Wild. Space, time, even reality itself, start to feel like a puzzle you can almost figure out.
• Honestly, I didn’t get every single part, and that’s okay. You don’t need a PhD to learn from it. You just need to be curious—and patient.
• It made me feel small and smart at the same time. There’s something about looking at the stars and thinking, “Huh, I kinda get this now.”
• If you’re looking for the best books to stimulate your intelligence and feel a bit like a genius afterward, this one’s for you.

36. Make It Stick by Peter C. Brown, Henry L. Roediger III, and Mark A. McDaniel

Struggling to remember what you studied? This book flips your learning habits with proven strategies that make information stick, so you learn faster and retain more.

• I wish I had read this in high school. Seriously. I used to cram and forget everything. This showed me why that doesn’t work—and what does.
• Spaced repetition, retrieval practice, mixing topics—this isn’t boring advice. It’s science-backed and surprisingly doable, even if you hate flashcards.
• One tip that helped me? Testing myself before I felt ready. It was awful at first. But it worked. My recall improved like crazy.
• This book is gold if you want to improve memory or increase your brain’s ability to handle tough material. No fluff, just smart habits.
• The authors break down how smart people—real geniuses—train their minds. It’s not talent. It’s how they study. That shocked me.
• Whether you’re in school, learning a new job, or just trying to read more intelligent books, this one teaches you how to remember what you read.

37. The Procrastination Equation by Piers Steel

Keep putting things off? This book shows the science behind why you procrastinate and gives you real strategies to beat it, so you can finally get things done and feel in control.

• If you think procrastination is just laziness—nope. This book shows it’s more about emotions, rewards, and self-doubt. I felt called out. In a good way.
• The “equation” sounds mathy, but don’t worry. It’s just a smart way of explaining how time, value, and delay mess with your motivation.
• I used the “10-minute rule” from this book—start something for just 10 minutes. Boom. I usually end up finishing the whole task.
• This is one of those intelligent books that sneaks psychology into real life. It’s not preachy. It’s more like, “Here’s why you do this. Now let’s fix it.”
• I liked how honest it was. It didn’t try to make me feel better for procrastinating. It gave me tools instead.
• If you want to become more productive and stop feeling behind all the time, this one can help without making you feel guilty.

38. Uncommon Sense Teaching by Barbara Oakley, Beth Rogowsky, and Terrence Sejnowski

Want to learn smarter, not harder? This book blends science and practice to help both teachers and learners use proven brain-based methods to boost understanding and retention.

• Whether you're a teacher or just trying to teach yourself stuff (like I was), this book explains how your brain learns—and how to help it.
• One idea I loved: switching between “focused” and “diffuse” thinking. You need breaks. Your brain figures stuff out in the background.
• The authors don’t assume you’re a genius. They show how even average people (hi!) can get smarter with the right techniques.
• I used their chunking method when learning math. It finally clicked. Like, after years of hating it, I got it. That’s wild.
• This is one of the most useful books for people who want to get smarter without just grinding longer hours.
• Whether you're a student, a teacher, or just curious, it’s one of the best reads to improve how you think, remember, and explain.
