Ellsworth Huntington

If there was ever any truth to the trickle-down theory, the only evidence of it I've ever seen was in that period of 1960 to 1965. All of sudden they were handing out major label recording contracts like they were coming in Cracker Jack boxes.
Dave Van Ronk

Joseph Lancaster

Essential to the theory of evolution is the premise that everything has come into being by itself.
Walter Lang

The monopoly of science in the realm of knowledge explains why evolutionary biologists do not find it meaningful to address the question whether the Darwinian theory is true.
Phillip E. Johnson

Minimalism now is a reaction to what came before. It's absolutely of its time. Music moved into the set theory thing, and moved out of it.
Harrison Birtwistle

It's easy to get next to music theory, especially between your peers and music classes and so forth. You just pay attention. I had a good ear, so I realized that printed music was just about reminding you what to play.

Wilhelm Ostwald

I think about the cosmic snowball theory. A few million years from now the sun will burn out and lose its gravitational pull. The earth will turn into a giant snowball and be hurled through space. When that happens it won't matter if I get this guy out.
Bill Lee

Our concern, however, is with slavery as it is, and not with any theory of it.

Kenneth L. Pike

What remains constant for me, during the last 15 years, has been the conviction that the cold war was a calamity for the entire world, and that it can be justified by no consideration of theory, nor by any supposed national interest.
Earl Browder

I had some hesitations about philosophy because, if you worked out a philosophical theory, it was hard to know whether you were going to be able to prove it or whether other theories had just as good a claim on belief.
Stephen Cole Kleene

Your candor is worth everything to your cause. It is refreshing to find a person with a new theory who frankly confesses that he finds difficulties, insurmountable, at least for the present.

Of thousands of others, nearer the centre of the explosion, there was no trace. They vanished. The theory in Hiroshima is that the atomic heat was so great that they burned instantly to ashes - except that there were no ashes.
Wilfred Burchett
