Plato, Laws 863d

but the cause of childish and senile sins when it is joined with weakness; and these last he will count as sins and he will ordain laws, as for sinners, but laws that will be, above all others, of the most mild and merciful kind. That is reasonable. And pretty well everyone speaks of one man being superior, another inferior, to pleasure or to passion; and they are so. Most certainly. But we have never heard it said that one man is superior, another inferior, to ignorance.
