A philosopher who regards ignorance of a scientific theory as a sufficient reason for not writing about it cannot be accused of complete lack of originality, as a study of recent philosophical literature will amply prove.
C. D. Broad, Scientific Thought, London, 1923, p. 3
Almost anybody can learn to think or believe or know, but not a single human being can be taught to feel. Why? Because whenever you think or you believe or you know, you’re a lot of other people: but the moment you feel, you’re nobody-but-yourself. To be nobody-but-yourself–in a world which is doing its best, night and day, to make you everybody else–means to fight the hardest battle which any human being can fight; and never stop fighting.
