10 Most Difficult Philosophy Books All Time

Hardest Philosophy Books

Books are a fantastic resource for knowledge, a catalog of humanity’s collective information. Philosophy books are one of the greatest sources of knowledge and information.

Conventionally, people would have picked up a philosophy book and tried to decode every one of the philosophy’s messages with perfect scrutiny. To properly understand a philosopher, they think to read one passage repeatedly until they can perfectly understand.

That is a disastrous way to approach philosophical texts but also drives you insane. There is an overarching statement or argument with every philosophical text the author is going at. So philosophy books are not always simple as other books.

Difficult philosophy books push the boundaries of your thinking and challenge you to grapple with complex ideas. They require focused attention and mental effort, which can stimulate your intellect and expand your capacity for abstract reasoning. So, reading difficult philosophy books can be challenging but rewarding.

10 Most Difficult Philosophy Books

Most book lovers avoid philosophy books because of their complexity and controversy. Also, philosophy books take a long time to read and understand. But these books are a must-read if you want to know about ancient culture, science, behavior, and other historical aspects. So we will discuss the 10 most difficult philosophy books of all time.

1. The Story Of Philosophy

The Story Of Philosophy is perfect for introducing philosophy and a structured overview. Durant brilliantly goes through the history philosophy as a narrative highlighting a new individual with each chapter. He talks about them as a person, their philosophical achievements, and how they relate to and affect the development of philosophy as a subject.

He also does a fantastic job showing how each philosopher impacted world history and their subject, which is a fascinating read. But the book is difficult to read because its basic introduction is high and has complex content that confuses some. It’s essential for anyone interested in philosophy.

2. On The Shortness of Life

Without a doubt, the book had the biggest impact on me. Seneca guides living a fulfilling life, encouraging us to make the most of our time and use that time wisely. Some expert readers find it hard to read a classic book because of old scenarios and social culture.

On The Shortness of Life is a masterpiece because every book’s word remains true despite being written two thousand years ago. Also, it can be applied to modern life, perfectly fitting into only 100 pages. This is a must-read for anybody, even those not yet captured by philosophy.

3. Plato’s Republic

Another outright classic by one of the godfathers of philosophy is Plato. He is one of the Greeks who helped birth and establish the subject. The book is The Republic. One of the most fascinating in his catalog is not a stretch to say that the next two thousand years of society have their roots firmly planted in the morals and teachings in the pages of the Republic.

It is possibly one of the most influential writings of all time and a staple for any philosophy. Plato is a deep thinker and literary. So the quotes and explanations are difficult to understand.

4. Beyond Good And Evil

What we’ve covered so far is fairly accessible, but Beyond Good and Evil will put your intellect to the test. Unlike Seneca, Nietzsche does not offer a relaxing afternoon read but one that will truly challenge you as a thinker and force you to ponder every point made. Don’t expect to understand everything on the first read. This book will be one of the most influential reads ever. Also, it is the most challenging philosophy book I have ever read.

5. Being and Nothingness

Being and Nothingness is one of the most important philosophical books written by the fascinating Paul Sartre in the last hundred years. It’s one of the most powerful looks into reality. Ever written with dense content and language can be a tricky one. But it would be a priceless addition to your collection, where much Western philosophy lies hidden under layers of context, written in forgotten languages and talking about the most complex metaphysical questions.

6. The Analects

The Analects is a classic that can change lives. The teachings of Confucius are digestible and straightforward, sometimes resulting in a mere sentence. But the meaningless and helpfulness stretch beyond your comprehension. You’ll find yourself using the advice in this book, and every aspect of your life is truly one of the most valuable books. If you can handle the most complex philosophy, then try it.

7. Critique of Pure Reason

Immanuel Kant is one of the most revered philosophers of all time, and Critique of Pure Reason is one of his most important contributions. The philosophy in this book is complicated and unique.

In Critique of Pure Reason, he breaks Adel’s deep into many aspects of life and showcases numerous groundbreaking falls, he can’t turn philosophy on its head with his work. People are still trying to understand it fully today. He’s certainly not one for the casual reader. But if you want to see some of the most in-depth and intelligent additions to the subject, Critique of pure reason is an excellent place to start.

8. Candide

Voltaire is one of my favorite philosophers and truly one of the most interesting. Not only did he do many fantastic things in his life, but how he did them is amazingly entertaining. Candide is one of Voltaire’s most elegant works. He writes a fabulous story about our character.

Candide tying in many of his philosophical beliefs is very accessible. Voltaire offers a welcome touch of theatre into our philosophy in a world of cryptic German philosophers and ancient Greek scriptures. Remember that the book is adamant about reading and understanding. As a difficult book, read one sentence 3/5 times, repeat it, and take time to understand.

9. Politics

Returning to another Greek classic, Essential Politics by Aristotle is one of the greatest philosophers of all time. Much like many classic writings on this list, politics delves deep into the core of its subject matter, tackling the basics and turning them into complicated dialogue. Whether you’re getting into philosophy or have been reading for years, this is for you.

10. A Treatise on Human Nature

David redefines many philosophies, changing how we approach and interact with this subject. As we were human, this was a critical and groundbreaking piece in many aspects of his work. It is one of the most important works in contemporary philosophy and general, which is impressive considering how Hume arrived after most of his peers.

A Treatise of Human Nature is a great read, and David Hume is such a fascinating individual. It is one of the most difficult books you feel nervous about and overthink.

Most Important Philosophy Book

Choosing important philosophy books is difficult because the importance of a philosophical work depends on the context, the historical period, and the field of philosophy. However, some books have significantly impacted the development of philosophy and continue to be influential. A few of these key works include:

Plato’s “Republic”: A foundational work in Western philosophy, this Socratic dialogue examines various topics such as justice, politics, and the nature of the human soul.

Aristotle’s “Nicomachean Ethics”: A cornerstone of ethical thought, this work by Aristotle explores the concept of happiness and virtue as the basis for living a good life.

René Descartes’ “Meditations on First Philosophy”: This work, which famously contains the phrase “Cogito, ergo sum” (I think, therefore I am), is a foundational text in modern philosophy and epistemology.

Immanuel Kant’s “Critique of Pure Reason”: Kant’s groundbreaking work tackles the limits and possibilities of human knowledge, bridging the gap between rationalism and empiricism.

John Stuart Mill’s “Utilitarianism”: This work offers a clear and concise articulation of the utilitarian ethical theory, which has been highly influential in moral and political philosophy.

These are a few examples of essential philosophy books, and there are many more influential works across various fields of philosophy. The significance of a particular book can also vary depending on a reader’s interests, background, and philosophical inclinations.

Crazy Philosophy Books

The term “crazy” can be ambiguous and might refer to books that present unconventional, controversial, or mind-bending ideas. Some philosophy books that could be considered “crazy” in this sense include:

Thus Spoke Zarathustra by Friedrich Nietzsche: This work presents Nietzsche’s philosophical ideas in a unique, poetic style and explores themes such as the death of God, the Übermensch, and the eternal recurrence.

Simulacra and Simulation by Jean Baudrillard: Baudrillard’s work delves into the concepts of hyperreality and the relationship between reality and its representations, which can be disorienting and thought-provoking.

The Society of the Spectacle by Guy Debord: This book critiques modern consumer society and the role of the “spectacle” in shaping our perceptions of reality, offering a challenging and provocative perspective on contemporary culture.

The Conspiracy Against the Human Race by Thomas Ligotti: Ligotti’s work is a blend of horror fiction and philosophy, exploring the darker aspects of human existence and arguing that consciousness is a tragic mistake of evolution.

Anti-Oedipus: Capitalism and Schizophrenia by Gilles Deleuze and Félix Guattari: This influential work in post-structuralist thought presents a complex critique of capitalism, psychoanalysis, and traditional philosophical categories.

These books offer challenging ideas that can provoke and expand one’s thinking. However, remember that these works may be more challenging to engage with and might not be the best starting point for someone new to philosophy.

Which Philosopher Is Most Difficult To Read?

Difficulty depends on the reader’s background, interests, and familiarity with philosophical concepts. However, some philosophers are commonly considered challenging due to their writing style, the complexity of ideas, or both. Some examples include:

Immanuel Kant: Immanuel is known for his dense prose and intricate argumentation. His “Critique of Pure Reason” is particularly challenging for readers.

Georg Wilhelm Friedrich Hegel: Hegel’s “Phenomenology of Spirit” and “Science of Logic” are notorious for their difficulty. His dialectical method and unique terminology make his writings hard to understand without considerable study.

Martin Heidegger: Heidegger’s magnum opus, “Being and Time,” is famous for its convoluted language and complex concepts, which require deep engagement and contemplation.

Jacques Derrida: As a leading figure in post-structuralism, Derrida’s “Of Grammatology” and “Writing and Difference” are dense and full of neologisms, making them difficult to parse for many readers.

What Is The Hardest Nietzsche Book To Read?

Friedrich Nietzsche’s works can be challenging to read due to his unique writing style, which incorporates aphorisms, metaphors, and poetic language. While some of his books are more accessible than others, one of the more difficult Nietzsche books to read is often considered to be “Thus Spoke Zarathustra.”

“Thus Spoke Zarathustra” is highly symbolic and metaphorical, using a fictional narrative to present Nietzsche’s philosophical ideas. The book is divided into four parts and follows the character Zarathustra, who embodies Nietzsche’s ideas and delivers them through speeches and parables. The work covers themes such as the Übermensch, the death of God, the will to power, and eternal recurrence.

The difficulty in reading “Thus Spoke Zarathustra” arises from its non-linear structure, the dense symbolism. The necessity of interpreting the symbolic narrative to uncover philosophical ideas. This can be demanding, especially for readers unfamiliar with Nietzsche’s thoughts and symbolism in intellectual works.

However, suppose you’re interested in exploring Nietzsche’s ideas. Some of his other works, such as “Beyond Good and Evil” or “On the Genealogy of Morals,” might be more approachable starting points. They present his thoughts more straightforwardly and systematically.

How Should You Read Philosophy Books?

Reading philosophy books is challenging, especially if you’re new to the subject. Here are some tips on how to approach reading philosophy books:

Be patient and persistent: Philosophy books can be dense and complex. Take your time reading and re-reading passages to ensure you understand the presented ideas. Be prepared to spend more time on a philosophy book than a novel or non-fiction book.

Read actively: Engage with the text by taking notes, summarizing arguments, and asking questions. This can help you better understand and remember the content.

Break down arguments: Identify the main points, premises, and conclusions of the ideas presented. Understanding the structure of an argument can help you evaluate its validity and soundness.

Look for examples and counterexamples: These can help you grasp abstract concepts and better understand the arguments’ implications.

Read secondary literature: Supplementary materials, such as commentaries or explanations of philosophical work, can help clarify complex concepts or arguments. Be sure to consult reliable sources, such as academic articles, books, or lectures.

Discuss with others: Conversing about the ideas in a philosophy book can help solidify your understanding and expose you to different perspectives. Consider joining a philosophy discussion group or taking a course to learn alongside others.

Be open-minded and critical: Philosophy challenges conventional wisdom and encourages questioning. Approach the material with an open mind and be prepared to evaluate the arguments and ideas presented critically.

Read in context: Understanding the historical and philosophical context in which a work was written can help you better appreciate its significance and relevance. Please familiarize yourself with the author’s background, influences, and the broader philosophical debates of their time.

Establish a reading plan: Philosophy books can be dense. So it might be helpful to establish a reading plan to break the material into manageable chunks. This can help you maintain momentum and give yourself enough time to absorb and reflect on the ideas.

Read multiple works: To get a broader understanding of a topic or a philosopher’s ideas, consider reading various books or essays by the same author or by different authors who address the same issue.

Remember that reading philosophy is a skill that improves with practice. The more you read and engage with philosophical texts, the more adept you will become at understanding and analyzing complex ideas and arguments.

Which Book Is Best To Start With Philosophy?

Selecting a book to start with philosophy depends on your interests and prior knowledge. A good starting point for many is a general introduction to the subject, which provides an overview of key ideas, thinkers, and historical periods. Some recommended introductory books include:

Sophie’s World by Jostein Gaarder: This novel combines fiction and philosophy, presenting the history of Western philosophy through the story of a young girl named Sophie.

The Problems of Philosophy by Bertrand Russell: This accessible book introduces fundamental philosophical questions and arguments.

A History of Western Philosophy by Bertrand Russell: This comprehensive work presents an overview of Western philosophy from ancient Greece to the early 20th century, providing insights into the ideas and lives of prominent philosophers.

Think A Compelling Introduction to Philosophy by Simon Blackburn: This book offers an engaging and accessible overview of the main themes and problems in philosophy, including topics such as knowledge, ethics, and free will.

Philosophy – The Basics by Nigel Warburton: This approachable introduction to philosophy covers critical areas, including ethics, political philosophy, and the philosophy of mind.


These books serve as a good starting point for newcomers to philosophy. As you become more familiar with the subject, you can delve into the original works of philosophers that interest you or explore specific areas, such as ethics, metaphysics, or epistemology, in greater depth.

So I hope you have a new set of books to get stuck into. I’m sure you have learned about countless helpful philosophical thoughts from across the years. If you are interested in reading any of these books, please discuss them with your book community because all of these ten books are complex and confusing. But if you catch them, you will collect vast amounts of knowledge.
