Try not to become a man of success but rather try to become a man of value.

I am strongly drawn to the simple life and am often oppressed by the feeling that I am engrossing an unnecessary amount of the labor of my fellow. I regard class differences as contrary to justice and, in the last resort, based on force. I also consider that plain living is good for everybody, physically and mentally.

Knowledge of what is does not open the door directly to what should be.

God may be subtle, but he isn't plain mean.

Teaching should be such that what is offered is perceived as a valuable gift and not as hard duty. Never regard study as duty but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs.

At least once a day, allow yourself the freedom to think and dream for yourself.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.
