Curb Quotes (1 quote)
La necessità è maestra e tutrice della natura; La necessità è tema e inventrice della natura e freno e regola eterna.
Necessity is the mistress and guide of nature. Necessity is the theme and the inventress, the eternal curb and law of nature.
S. K. M. III. 49a. As translated by Jean Paul Richter, in 'Philosophical Maxims', The Literary Works of Leonardo da Vinci: Compiled and Edited from the Original Manuscripts (1883), Vol. 2, 285, Maxim 1135.

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) --
