The Problem With Deduction

The point of philosophy is not to know everything, but to know how to approach any given problem. I feel like the things that we can know for certain are a lot of conditional phrases. That's another way of expressing the Socratic. The only thing that I know is that I know nothing because I can sort of see the logical hinges between the various things that I don't know. At least that's the idea that you could talk about nothing intelligently.
