What is a philosophical and thought provoking book?

I’m not sure if there’s one specific book that comes to mind, but some great philosophical reads include things like Plato’s Republic, Aristotle’s Nicomachean Ethics, and Kant’s Critique of Pure Reason.

These books explore timeless questions about the nature of justice, the good life, morality, and the limits of human knowledge. They’re dense reads, but they offer a unique perspective on some of the most fundamental questions we can ask about ourselves and the world around us.
