I have skipped the quotation instalment from the last two weeks, so this is more than overdue.
"For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." - Richard P. Feynman, American theoretical physicist, 1918-88
"It hath been often said, that it is not death, but dying, which is terrible." - Henry Fielding, English novelist and dramatist, 1707-54
"Never cry over spilt milk, because it may have been poisoned." - W. C. Fields, American humorist, 1880-1946
"The best causes tend to attract to their support the worst arguments." - R. A. Fisher, English statistician and geneticist, 1890-1962
I like to think that the last quotation is referring to most environmental and animal rights groups.
