Also I recommend Blackwell’s Anthology of Analytic Philosophy.
Typically the direction starts with Descartes, then Hume, then Kant, and after that, there is a real break between continental and analytic traditions. So, jumping into Wittgenstein might be a really bad idea for someone without a background, but who knows. The Philosophical Investigations is a fairly approachable book.
You don't need a background, unless you want to read the middle section, which is close to advanced maths.
<Googles "works of Wittgenstein">. Ohh, the Tractatus. Ok. "You don't need a background" is absurd! Sure, you can physically read the words. But you won't have a clue why he's saying what he's saying, or what he meant by it. And Wittgenstein himself within a few years would've told you it's nonsense and not to go anywhere near it.
That's true of (at least) all important philosophy books, isn't it?
