Virtue is uniform, conformable to reason, and of unvarying consistency; nothing can be added to it that can make it more than virtue; nothing can be taken from it, and the name of virtue be left.
Sed nescio quo modo nihil tam absurde dici potest quod non dicatur ab aliquo philosphorum. (There is nothing so absurd but some philosopher has said it.)
While all other things are uncertain, evanescent, and ephemeral, virtue alone is fixed with deep roots; it can neither be overthrown by any violence or moved from its place.
Nothing is so unpredictable as a throw of the dice, and yet every man who plays often will at some time or other make a Venus-cast: now and then he indeed will make it twice and even thrice in succession. Are we going to be so feebleminded then as to aver that such a thing happened by the personal intervention of Venus rather than by pure luck?
