These are quotes that I have retired from my website's banner, but still quite like.
"On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ [...] I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."- Charles Babbage, Passages from the Life of a Philosopher (1864)
