I actually would encourage you to start with the Socratic Dialogues. Greek philosophy is at the root of western philosophy and so much thought in general.

They are extremely short and accessible and use plain language. The Dialogues, like any philosophy, have their flaws, but I think they do a great job of teaching a certain way or analyzing an idea.

They were actually written by Plato (Socrates left no written material behind) but are the closest we have to Socrates and Socratic thought.

I personally found a course on the fundamentals of western philosophy super fascinating. Aside from the dialogues the primary sources can be tough going so a class or a reputable-looking reader on each thinker (good used bookstores will have these, or just google and get whatever is most recent and recommended) is recommended. In rough chronological order:

- Socrates - Plato - Descartes (I don’t know much about medieval though and have skipped over it) - Spinoza - Rousseau - Kant (can be dense/boring) - Hegel

The fascinating thing is to read each thinker, absorb their conception of things, and learn what they got _wrong_. And then to read the next thinker and learn what _they_ got wrong!

These are all pseudo, pop-science books. I would recommend reading the works of actual scientists and philosophers directly, or textbooks.

This is not a contribution. Telling someone asking for enjoyable books to read to skip bestselling books by Nobel laureates to instead read textbooks, whitepapers and other raw sources makes you sound like a pretentious asshole.

Are there any particular ones you could recommend?
