[155] This is he who not only rejoiced in a few species of desire, but who also chose to pass by none whatever entirely, so that he might obtain the whole entire genus in which every species is included; for it is said that, "the mixed multitude that was among them desired all kinds of concupiscence," [153] that is to say, the very genus of concupiscence itself, and not some one species; and sitting down they wept. For the mind is conscious that it is possessed of but slight power, and when it is not able to obtain what it desires, it weeps and groans; and yet it ought to rejoice when it fails to be able to indulge its passions, or to become infected with diseases, and it ought to think their want and absence a very great piece of good fortune.
