Knowledge is happiness, because to have knowledge — broad, deep knowledge — is to know true ends from false, and lofty things from low.

Life is either a daring adventure, or nothing

Let pessimism once take hold of the mind, and life is all topsy-turvy, all vanity and vexation of spirit. There is no cure for individual or social disorder, except in forgetfulness and annihilation. "Let us eat, drink and be merry," says the pessimist, "for to-morrow we die." If I regarded my life from the point of view of the pessimist, I should be undone. I should seek in vain for the light that does not visit my eyes and the music that does not ring in my ears. I should beg night and day and never be satisfied. I should sit apart in awful solitude, a prey to fear and despair. But since I consider it a duty to myself and to others to be happy, I escape a misery worse than any physical deprivation.

Truly I have looked into the very heart of darkness, and refused to yield to its paralyzing influence, but in spirit I am one of those who walk the morning. What if all dark, discouraging moods of the human mind come across my way as thick as the dry leaves of autumn? Other feet have traveled that road before me, and I know the desert leads to god as surely as the green, refreshing fields, and orchards.
