325. Nevertheless, as very often there are divers courses to choose from, one might, instead of the balance, compare the soul with a force which puts forth effort on various sides simultaneously, but which acts only at the spot where action is easiest or there is least resistance. For instance, air if it is compressed too firmly in a glass vessel will break it in order to escape. It puts forth effort at every part, but finally flings itself upon the weakest. Thus do the inclinations of the soul extend over all the goods that present themselves: they are antecedent acts of will; but the consequent will, which is their result, is determined in the direction of that which touches most closely. 326. This ascendancy of inclinations, however, does not prevent man from being master in his own domain, provided that he knows how to make use of his power. His dominion is that of reason: he has only to prepare himself in good time to resist the passions, and he will be capable of checking the vehemence of the most furious. Let us assume that Augustus, about to give orders for putting to death Fabius Maximus, acts, as is his wont, upon the advice a philosopher had given him, to recite the Greek alphabet before doing anything in the first heat of his anger: this reflexion will be capable of saving the life of Fabius and the glory of Augustus. But without some fortunate reflexion, which one owes sometimes to a special divine mercy, or without some skill acquired beforehand, like that of Augustus, calculated to make us reflect fittingly as to time and place, passion will prevail over reason. The driver is master over the horses if he controls them as he should, and as he can; but there are occasions when he becomes negligent, and then for a time he will have to let go the reins: _Fertur equis auriga, nec audit currus habenas_.
