My resource list
I struggle sometimes, where to begin in a new field, that i'm interested in. Here are some helpful links:
If you need a reliable source of philosophy, alot of the universities have free ressource pages:
Stanford http://plato.stanford.edu/entries/freewill/
MIT http://ocw.mit.edu/courses/linguistics-and-philosophy/
Ted Talks are also a great source, to start into the field of philosophy:

Personally i'd recommend everyone Who am I, and if so how many? from german author Richard David Precht. A funny and well written story into the field of philosophy paired with neurosience and a good sense of humor onto the more serious questions of our existence.
