The greatest and saddest defect is not credulity, but an habitual forgetfulness that our science is ignorance.
Henry David ThoreauIf you would learn to speak all tongues and conform to the customs of all nations, if you would travel farther than all travellers, be naturalized in all climes, and cause the Sphinx to dash her head against a stone, even obey the precept of the old philosopher, and Explore thyself. Herein are demanded the eye and the nerve. Only the defeated and deserters go to the wars, cowards that run away and enlist.
Henry David ThoreauTo say that God has given a man many and great talents frequently means that he has brought his heavens down within reach of his hands.
Henry David Thoreau
