Love is of all stimulants the most powerful. It sharpens the wits like danger, and the memory like hatred; it spurs the will like ambition; it exalts the imagination like hashish; it intoxicates like wine.
In novel, Debenham’s Vow (1870, publ. Hurst and Blackett), Vol. 1, 137. In later collections of quotations, the phrase about “imagination” is omitted, for example, in Maturin M. Ballou (ed.), Edge-Tools of Speech (1886), 284.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) -- Carl Sagan
