Philosophy has a hazing problem. Ask where to start and someone will hand you Kant's Critique of Pure Reason — one of the most difficult books ever written — and a week later you've concluded philosophy isn't for you. It is. You were just handed the final exam on day one.
Story before system
The right first move is a book that teaches the shape of philosophy before the rigor. That's why our philosophy path opens with Sophie's World — a novel that walks the entire history of Western thought — alongside Russell's short, sharp The Problems of Philosophy. One gives you the map; the other shows you what a philosophical argument actually feels like.
The path, stage by stage
First steps — Sophie's World, The Problems of Philosophy, and Blackburn's Think: the vocabulary and the cast of characters.
The Western canon — now the originals, chosen for readability: Plato's The Last Days of Socrates (philosophy as drama), Aristotle's Nicomachean Ethics, and Descartes' Discourse on Method and Meditations. These are far more approachable than their reputations suggest — Plato especially reads like a courtroom thriller.
The core branches — Hume's Dialogues Concerning Natural Religion, Kant's Groundwork of the Metaphysics of Morals (the short one — this is where Kant belongs, not at the start), and Mill's Utilitarianism.
Modern movements — Sartre's Existentialism Is a Humanism, Wittgenstein, and Chalmers' The Conscious Mind on the puzzle of consciousness.
The frontier — Rawls' A Theory of Justice and MacIntyre's After Virtue: philosophy as a live, unfinished argument.
The habit that makes it stick
Philosophy rewards slow reading and arguing back. After each book, write one paragraph: what is this philosopher's strongest claim, and where do I think it fails? That single exercise converts reading into thinking — which is the entire point.
Fourteen books sounds like a lot; at a relaxed pace it's a year of the best conversation of your life. Follow the path, or start narrower with the Stoics in the right order.
