All of these lower psychical faculties have a physiological significance. Acquisitiveness functionally expresses assimilation, accretion, animal growth, and tends to bodily repletion. Secretiveness expresses concealing, separating, withdrawing, and functionally signifies secretive action. Secretion is the separating and withdrawing from the blood some of its constituents, as mucus, bile, saliva, etc. This latter process indicates complex conditions of organization, so that the higher and more complex the tissue, the greater the number of secretory organs. Unrestrained selfishness, while it naturally conserves the individual interests, in its ultimate tendencies, is the very essence of human depravity. Without qualification, clearly, it is crime, for blind devotion to the individual must be in utter disregard for the good of others. The ultimate tendencies of these faculties are, therefore, criminal. Exaggerate the faculty of acquisitiveness, and it becomes avariciousness. Develop secretiveness and selfishness, and they become cunning and profligacy, desperation and crime. Their functional development tends to produce physical disorder and violent disease. All of these faculties are vehement, contentious, thriving by opposition. Life itself has been called a forced state, because it wars with the elements it appropriates, and transmutes their powers into vitality. [Illustration: Fig. 86.] We find men and women of this temperament, who are models of character and organization. George Washington is an excellent illustration. The impression that his presence made upon the Marquis de Chastellux, is given in the following words: "I wish only to express the impression General Washington has left on my mind; the idea of a perfect whole, brave without temerity, laborious without ambition, generous without prodigality, noble without pride, virtuous without severity." Gen. Scott, Lord Cornwallis, Dr. Wistar, Bishop Soule John Bright, Jenny Lind Goldsmidt, and Dr. Gall are good representatives of this temperament. Fig. 86 is an excellent illustration of it, finely blended and well balanced, in the person of Madame de Stael. This temperament requires fewer tonics and stimulants than the lymphatic. This constitution is best able to restore vital losses. It is a vital temperament, in other words, it combines favorably with all the others, and better adapts itself to their various conditions. Some regard it as the best adjusted one in all its organs and tissues, and as the most satisfactory and serviceable. [Illustration: Fig. 87.]
