I find Spinoza very approachable. Much of what he said resonates with me. For anyone unfamiliar, this is a light but entertaining introduction to some of his ideas:

If you start the Ethics at the end you find a great introduction to reading Spinoza:
> But all things excellent are as difficult as they are rare.
It's from this I also derive my belief that if you find Spinoza "approachable" then you probably haven't spent enough time with Spinoza.
