That folly of old age which is called dotage is peculiar to silly old men, not to age itself.

I know that it is likely that as worship of the gods declines, faith between men and all human society will disappear, as well as that most excellent of all virtues, which is justice.

That which is usually called dotage is not the weak point of all old men, but only of such as are distinguished by their levity.

Through doubt we arrive at the truth.

Our span of life is brief, but is long enough for us to live well and honestly.

Armed forces abroad are of little value unless there is prudent counsel at home

The home is the empire! There is no peace more delightful than one's own fireplace.
