Aristotle on age

It is the mark of an educated mind to be able to entertain a thought without accepting it.

Courage is the first of human qualities because it is the quality which guarantees the others.

Man is by nature a political animal.

When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around.
But when I got to be 21, I was astonished at how much the old man had learned in seven years.

And in the end, it’s not the years in your life that count. It’s the life in your years.

Age is an issue of mind over matter. If you don’t mind, it doesn’t matter.
