Knowledge is power." Rather, knowledge is happiness, because to have knowledge - broad, deep knowledge - is to know true ends from false, and lofty things from low. To know the thoughts and deeds that have marked man's progress is to feel the great heart-throbs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.
Helen KellerThat the sky is brighter than the earth means little unless the earth itself is appreciated and enjoyed. Its beauty loved gives the right to aspire to the radiance of the sunrise and sunset.
Helen KellerIf 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.
