MASTERY OF THESE CORPOREAL DISPOSITIONS IS NOT EASY.
It may be objected that one ought to master these dispositions of the body. But the principle that could triumph over them is pure only if it flee from here below. The appetites which exercise the greatest force come from a certain complexion of the body, and differ according to its nature. Consequently, it is not easy to master them. There are men who have no judgment, because they are cold and heavy on account of their bad constitution. On the contrary, there are others who, because of their temperament, are light and inconstant. This is proved by the difference of our own successive dispositions. When we are gorged, we have appetites and thoughts that differ from those we experience when starved; and our dispositions vary even according to the degrees of satiety.
