Niccolò Machiavelli,
Discourses on Livy (Neville) — Second Book…
(1531)
“ But returning to our argument, I say that, if the judgment of men is corrupt in deciding whether the present or the ancient age is better, in those things where because of their antiquity they cannot have a perfect knowledge as they have of their own times, the old men ought not to corrupt themselves in judging the times of their youth and their old age, they having known and seen the latter and the former equally. Which thing would be true if men throughout all the periods of their lives had the same judgment and the same appetites. ”
