Ask A Philosophical Question . . .

The other night my son Alex, as he was stepping into the shower, asked me "What controls our brain?" and I normally wouldn't be prepared to answer such a puzzler -- but I had just read over Marvin Minsky's book Society of the Mind in preparation for the philosophy class that I teach this semester -- so he received an extemproaneous lecture on consciousness, how it might be produced by various independent modules in our brain, how it leads to self-reflexive thought etc. etc. and I am certain he'll never ask that question again.
