A: a secondary non-autnomous act of second order, directed at an autonomous primary act of first order.

While the first act is consciousness of a content, the second act is consciousness of the act, and hence the most basic form of consciousness, since without it we would be mere stimulus-respons machines.
Q: Shouldn't we only ask yes/no questions?
