What nature requires is obtainable, and within easy reach. It is for the superfluous we sweat.

It is the superfluous things for which men sweat, - superfluous things that wear our togas theadbare, that force us to grow old in camp, that dash us upon foreign shores.

All art is but imitation of nature.

That moderation which nature prescribes, which limits our desires by resources restricted to our needs, has abandoned the field; it has now come to this - that to want only what is enough is a sign both of boorishness and of utter destitution.

For greed all nature is too little.

A happy life is one which is in accordance with its own nature.
