We must now consider Intention: concerning which there are five points of inquiry:
(1) Whether intention is an act of intellect or of the will?
(2) Whether it is only of the last end?
(3) Whether one can intend two things at the same time?
(4) Whether intention of the end is the same act as volition of the means?
(5) Whether intention is within the competency of irrational animals?
