Exobiology Quotes (2 quotes)
“Exobiology” … that peculiar science has no known subject matter.
In The Meaning of Evolution: A Study of the History of Life and of Its Significance for Man (Rev. Ed., 1967), 10, footnote.
Exobiology—a curious development in view of the fact that this “science” has yet to demonstrate that its subject matter exists!
In This View of Life: The World of the Evolutionist (1964), 254.

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) --
