I also consider that plain living is good for everybody, physically and mentally.
And yet everybody has certain ideals which determine the direction of his endeavors and his judgments. In this sense I have never looked upon ease and happiness as ends in themselves — such an ethical basis I call more proper for a herd of swine. The ideals which have lighted me on my way and time after time given me new courage to face life cheerfully, have been Truth, Goodness, and Beauty. Without the sense of fellowship with men of like mind, of preoccupation with the objective, the eternally unattainable in the field of art and scientific research, life would have seemed to me empty. The ordinary objects of human endeavor – property, outward success, luxury – have always seemed to me contemptible.
