Salient Quotes (2 quotes)

From opening paragraph of Preface, Quasars, Redshifts and Controversies (1987).
No matter how intently one studies the hundred little dramas of the woods and meadows, one can never learn all the salient facts about any one of them.
In 'April: Sky Dance', A Sand County Almanac, and Sketches Here and There (1949, 1987), 32-33.
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.

I cannot recall the last time something like that happened in politics or religion.
(1987) --
