Philosophers do it deeper. Philosophers do it a posteriori . Philosophers do it conceptually. Philosophers do it for pure reasons. Philosophers do it with their minds.

Philosophers wonder why they did it. One to change it and two to stand around arguing over whether or not the light bulb exists. Two, of course. This dialectic creates a synthesis which does the job. One to change it, and one not to change it.
