What makes me choose one thing over another? I sometimes think that it is some internal act of deliberation. But what is the nature of that internal deliberation? What is its source? Either the explanation stops there, or something else is responsible for my aptitude to will. I am convinced that the explanation continues.

My thought is that I choose what you do. My choices are governed -- and, a fortiori, necessitated -- by the members of my social network.

So much for the mysteriousness of the inner.
