We may divide thinkers into those who think for themselves and those who think through others. The latter are the rule and the former the exception. The first are original thinkers in a double sense, and egotists in the noblest meaning of the word.
Arthur SchopenhauerWhatever folly men commit, be their shortcomings or their vices what they may, let us exercise forbearance; remember that when these faults appear in others it is our follies and vices that we behold.
Arthur Schopenhauer
