De Plantatione

And the first and the most powerful argument is this: if no one in his senses would entrust a secret which he wished to be kept to a drunken man, then a good and wise man will not get drunk. But before we collect all the other arguments in their order, it may be better to reply to each objection separately, in order that we may not appear to be too prolix, and consequently to be troublesome.

Some one then will say in opposition that, according to the argument that has been advanced, the wise man must never have a bilious attack, and never go to sleep, and above all must never die. But he to whom some of these things happens is either an inanimate being or a divine one; but beyond all question he is not a man at all. Imitating this perversion of the arguments, one may apply it equally to a bilious man, or to a sleeping man, or to a dying man; for no one in his senses would tell a secret to a man in any of these conditions, but it would be reasonable for him to tell it to a wise man, for the wise man is never bilious, never goes to sleep, and never dies.
