[1.] They who drink bitter medicines, first submit to some unpleasantness, and afterwards feel the benefit. For such is virtue, such is vice. In the latter there is first the pleasure, then the despondency: in the former first the despondency, and then the pleasure. But there is no equality; for it is not the same, to be first grieved and afterwards pleased, and to be first pleased and afterwards grieved. How so? because in the latter case the expectation of coming despondency makes the present pleasure less: but in the former the expectation of coming pleasure cuts away the violence of present despondency; so that the result is that in the one instance we never have pleasure, in the latter we never have grief. And the difference does not lie in this only, but also in other ways. As how? That the duration is not equal, but far greater and more ample. And here too, it is still more so in things spiritual.
