Quod Deterius Potiori Insidiari Soleat

But to the impious Cain, neither does the earth contribute anything to give him vigour, even though he never concerns himself about anything which is exterior to it; on which account, in the next sentence, he is found "groaning and trembling upon the earth," [*](Genesis iv. 12. ) that is to say, under the influence of grief and terror; and such also is the miserable life of a wicked man, who has received for his inheritance the most painful of the four passions, pain and terror; the one being equivalent to groaning, and the other to trembling; for it is inevitable, that some evil should either be present to or impending over such a man. Now the expectation of impending evil causes fear, but the suffering of present evil causes pain.

On the other hand, he who pursues virtue is found to be in the enjoyment of corresponding blessings; for either he has acquired what is good or he will attain to it. Now the present possession perfects joy, which is the best of all possessions; but the expectation of possessing it brings hope, the food of those souls which love virtue; on account of which, putting away sluggishness, we, with spontaneous readiness, hasten onwards to good actions.
