Not less than two hours a day should be devoted to exercise, and the weather should be little regarded.

I am an Epicurean. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greek and Roman leave to us.

I never considered a difference of opinion in politics, in religion, in philosophy, as cause for withdrawing from a friend.

Leave all the afternoon for exercise and recreation, which are as necessary as reading. I will rather say more necessary because health is worth more than learning.

I had a very happy childhood, but I still used my imagination as a leisure resort.

I always appreciated the magnitude of my mother's imagination. She always saw beauty in what was broken, and she'd preserve it.

My mother was the most creative, fantastic person and would come up with great things for us to do. She'd buy art supplies and all of us would sit around painting. I was lucky.

Not to make too much of a claim for poetry, but this is a question that goes to the moral heart of the business of any art: 'How do you see the world, and what right do you have to see the world in the way that you do?'
