Any genuine philosophy leads to action and from action back again to wonder, to enduring fact of mystery.
The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.
Religion is a man using a divining rod. Philosophy is a man using a pick and shovel.
