To get an overview it makes sense to read about the history of philosophy. It's not practical to read all of platon, just to learn a few important ideas... Also there is not one true philosophy. Nietzsche is very different from Kant for example. One book I really want to recommend you: Sigmund Freud - The Interpretation of Dreams It's more a psychology book, but it is deeply philosophical. Freud tries to analyse how the brain works, using logic and observation of human behaviour.
