Definition.—Those acts are called human of which a man is the master, and he is master of his actions in virtue of his reason and his will, which faculties make him superior to non-human agents that act without reason and freedom. Hence, the following kinds of acts done by a human being are not called human: (a) those that are not under the control of the mind, because one is permanently or temporarily without the use of reason or without knowledge (e.g., the acts done by the insane; by those who are unconscious or delirious, under the influence of hypnotism or drugs, distracted or carried away by vehement fear, anger, etc.; by infants and uninstructed persons); (b) those that are not under the control of the will, even though they are known (e.g., automatic acts, such as the acts of the vegetative powers, growth, circulation of the blood; pathological acts, such as convulsions; acts done under external violence).
