Whether one habit is made up of many habits?

❌ Objection 1 : It would seem that one habit is made up of many habits. For whatever is engendered, not at once, but little by little, seems to be made up of several parts. But a habit is engendered, not at once, but little by little out of several acts, as stated above (Question [51], Article [3]). Therefore one habit is made up of several.

❌ Objection 2 : Further, a whole is made up of its parts. Now many parts are assigned to one habit: thus Tully assigns many parts of fortitude, temperance, and other virtues. Therefore one habit is made up of many.

❌ Objection 3 : Further, one conclusion suffices both for an act and for a habit of scientific knowledge. But many conclusions belong to but one science, to geometry, for instance, or to arithmetic. Therefore one habit is made up of many.
