/summa/FP/FPIX/FP_Q83:
We now inquire concerning free-will. Under this head there are four points of inquiry:
(1) Whether man has free-will?
(2) What is free-will---a power, an act, or a habit?
(3) If it is a power, is it appetitive or cognitive?
(4) If it is appetitive, is it the same power as the will, or distinct?
