1[114] “On thy breast and belly shalt thou go” (Gen. 3:14). For passion has its lair in these parts of the body, the breast and the belly. When pleasure has the materials it needs to produce it, it haunts the belly and the parts below it. But when it is at a loss for these materials, it occupies the breast where wrath is; for lovers of pleasure when deprived of their pleasures grow bitter and angry.

2[115] Let us look still more carefully at the thing signified. Our soul consists of three parts, and has one part given to reasoning, a second to high spirit, a third to desire. Some philosophers have distinguished these parts from each other in regard to function, some in regard also to the places which they occupy. These have gone on to assign to the reasoning part the region of the head, saying that, where the king is, there are also his bodyguards, and that the senses which are in the region of the head are bodyguards of the mind, and that it follows that the king must be there too, having had it allotted to him, like a castle in a city, for his dwelling. To the spirited part they assign the breast, pointing out that nature has given that part firmness by means of a strong and solid array of continuous bones, as though she were arming a good soldier with shield and breastplate for defence against opponents. To the lustful portion of the soul they assign the quarter about the abdomen and the belly, for there it is that lust, irrational craving, has its abode.
