For as I reflect on my career I believe I could have accomplished more if I had not cared so much what people thought of me. Natural Philosophy cannot advance without attacking theories that are old, and beating back new ones that are wrong, neither of which may be accomplished without doing some injury to their professors. I have been a mediocre Natural Philosopher not because I was stupid but because I was, after a fashion, cowardly. Today I shall try boldness for once, and be a better Natural Philosopher for it, and probably get you all hating me by the time I am done.
