comme telle, son existence est compatible avec les plus hautes intelligences." He discovers hereditary taint universally present in these cases. "Hérédité directe, hérédité indirecte, hérédité transformée, se trouve chez les génésiaques."
Passing to etiology, he rests mainly upon an organism predisposed by ancestry, and placed in a milieu favourable to its morbid development. Provocative causes are not sufficient to awake the aberration in healthy organisms, but the least thing will set a predisposed organism on the track. This, I may observe, seems to preclude simple imitation, upon which Moreau afterwards lays considerable stress; for if none but the already tainted can be influenced by their milieu, none but the tainted will imitate.
What he calls "General Physical Causes" are (1) Extreme Poverty, (2) Age, (3) Constitution, (4) Temperament, (5) Seasons of the Year, (6) Climate, (7) Food.
Extreme poverty leads to indiscriminate vice, incest, sodomy, &c. That is true, and we know that our city poor and the peasants of some countries are habitually immoral. Yet Moreau proves too much here. For, according to his principles, hereditary neurosis ought by this time to have become chronic, epidemic, endemic, in all the city poor and in all the peasants of all countries; which is notably not the fact. Puberty and the approach of senility are pointed out as times when genesiac symptoms manifest themselves. His observations upon the other points are commonplace enough; and he repeats the current notion that inhabitants of hot climates are more lascivious than those of the North.
