Science Quotes by Jean André Deluc (4 quotes)

According to the conclusion of Dr. Hutton, and of many other geologists, our continents are of definite antiquity, they have been peopled we know not how, and mankind are wholly unacquainted with their origin. According to my conclusions drawn from the same source, that of facts, our continents are of such small antiquity, that the memory of the revolution which gave them birth must still be preserved among men; and thus we are led to seek in the book of Genesis the record of the history of the human race from its origin. Can any object of importance superior to this be found throughout the circle of natural science?
— Jean André Deluc
An Elementary Treatise on Geology (1809), 82.

It will be contributing to bring forward the moment in which, seeing clearer into the nature of things, and having learnt to distinguish real knowledge from what has only the appearance of it, we shall be led to seek for exactness in every thing.

We may observe in some of the abrupt grounds we meet with, sections of great masses of strata, where it is as easy to read the history of the sea, as it is to read the history of Man in the archives of any nation.

Carl Sagan Thumbnail 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
