A just thinker will allow full swing to his scepticism. I dip my pen in the blackest ink, because I am not afraid of falling into my inkpot…. We are of different opinions at different hours, but we always may be said to be at heart on the side of truth. – Ralph Waldo Emerson, “Worship,” The Conduct of Life, 1860

No amount of energy will take the place of thought. A strenuous life with its eyes shut is a kind of wild insanity. – Henry Van Dyke
