It must be remembered that Quality is a very different thing from intellectuality or morality. A high Quality person may be immoral and not specially intellectual, although there is almost always a _keenness_ of perception, and almost intuitive recognition, in these cases--the immorality is generally lacking in coarseness, and is usually connected with perversion of the æsthetic faculties. In the same way, the person of low Quality often may be moral according to the code, but will be coarse in the manifestation of that virtue, and may possess a certain low cunning which with many persons passes for intellect and "brains." In speaking of Quality, the words "fineness" and "coarseness" come easily to the mind and tongue and are perhaps the terms most suggestive of the two extremes of this attribute of the Man. TEMPERAMENT Next in the order of consideration we find what is called _Temperament_. Temperament is defined as: "That individual peculiarity of organization by which the manner of acting, feeling and thinking of each person is permanently affected; disposition or constitution of the mind, especially as regards the passions and affections." Hippocrates, the ancient Greek philosopher-physician (B. C. 468-367) held to the existence of four temperaments, which he attributed to certain qualities of the blood and the several secretions of the body such as the bile, etc. While his theory was rejected by later investigators, his classification continued until very recently under the name of (1) the Sanguine; (2) the Lymphatic or Phlegmatic; (3) the Choleric or Bilious; and (4) the Melancholic temperaments, respectively. As a matter of general information on the subject we herewith give the old classification with the attributes of each class: The _Sanguine_ temperament was held to be characterized by red or light-brown hair, blue eyes, a fair or ruddy complexion, large arteries and veins, a full and rapid pulse, slight perspiration, impatience of heat, febrile tendency, and lively and cheerful temper, excitable passions, a warm, ardent, impulsive disposition, and a liking for active pursuits; The _Lymphatic_, or _Phlegmatic_ temperament was held to be characterized by light, sandy, or whitish hair, light grey eyes, pallid complexion, skin almost devoid of hair, flabby tissues, much perspiration, small blood-vessels, a feeble and slow pulse, want of energy, lack of activity, deficient spirit and vividness; The _Choleric_ or _Bilious_ temperament was held to be characterized by black hair often curling, black or hazel eyes, and dark but ruddy complexion, hairy skin, strong full pulse, firm muscles, great activity and positiveness, strength of character, and an active brain. The _Melancholic_ temperament was held to be characterized by black hair, black or hazel eyes, a dark leaden complexion, pulse slow and feeble, and a disposition toward study, poetry, literature, and sentiment.
