You can hardly convince a man of error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grand-children may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more, to prove that they are not to be referred to the Noachian deluge.
Henry David ThoreauYou think that I am impoverishing myself withdrawing from men, but in my solitude I have woven for myself a silken web or chrysalis, and, nymph-like, shall ere long burst forth a more perfect creature, fitted for a higher society.
Henry David ThoreauThe process of discovery is very simple. An unwearied and systematic application of known laws to nature, causes the unknown to reveal themselves. Almost any mode of observation will be successful at last, for what is most wanted is method.
