Every man has three types of character, in all of which he must be studied before he can be adequately represented. First he has his inherited constitutional or temperamental character, his fixed native character, in which the collective experience and qualities of his progenitors are consolidated, stamped, and transmitted. Next he has his peculiar fugitive or passional character, which is the modification of his stable average character under the influence of exciting impulses, temporary exaltations of instinct or sentiment. And then he has his acquired habitual character, gradually formed in him by the moulding power of his occupation and associations, as expressed in the familiar proverb, “Habit is a second nature.” The first type reveals his ancestral or organic rank, what he is in the fatal line of his parentage. The second shows his moral or personal rank, what he has become through his own experience and discipline, self-indulgence and self-denial. The third betrays his social rank, what he has been made by his employment and caste. The original estimate or value assigned to the man by nature is indicated in his constitutional form, the geometrical proportions and dynamic furnishing of his organs, his physical and mental make-up. The estimate he puts on himself, in himself and in his relations with others, his egotistical value, is seen in the transitive modifications of his form by movements made under the stimulus of passions. The conventional estimate or social value awarded him is suggested through the permanent modifications wrought in his organs and bearing by his customary actions and relations with his fellows. Thus the triple type of character possessed by every man is to be studied by means of an analysis of the forms of his organs in repose and of his movements in passion or habit.
