Diluvium Quotes (1 quote)
One will see a layer of smooth stones, popularly called fluitati [diluvium], and over these another layer of smaller pebbles, thirdly sand, and finally earth, and you will see this repeatedly … up to the summit of the Mountain. This clearly shows that the order has been caused by many floods, not just one.
In De' Corpi Marini che su Monti si Trovano (1721), 57, as translated by Ezio Vaccari.

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
