I tell you the past is a bucket of ashes, so live not in your yesterdays, no just for tomorrow, but in the here and now. Keep moving and forget the post mortems; and remember, no one can get the jump on the future.

Carl Sandburg

We have come tardily to the tremendous task of cleaning up our environment. We should have moved with similar zeal at least a decade ago. But no purpose is served by post-mortems. With visionary zeal but the greatest realism, we must now address ourselves to the vast problems that confront us.

Gerald R. Ford

The theory that thought is merely a movement in the brain is, in my opinion, nonsense; for if so, that theory itself would be merely a movement, an event among atoms, which may have speed and direction but of which it would be meaningless to use the words 'true' or 'false'.

C. S. Lewis

When I was at school studying biology, I wanted to be a medical researcher. I did work experience at St Mary's Hospital in London, and I begged them to let me see the post mortems. So the first time I saw a naked male was at 15, when I saw an 89 year old man who had died of a brain hemorrhage.

Creationists reject Darwin's theory of evolution on the grounds that it is "just a theory". This is a valid criticism: evolution is indeed merely "a theory", albeit one with ten billion times more credence than the theory of creationism - although, to be fair, the theory of creationism is more than just a theory. It's also a fairy story. And children love fairy stories, which is presumably why so many creationists are keen to have their whimsical gibberish taught in schools.

Charlie Brooker

If you take from a theory only the conclusions you like and discard the rest, you are using the theory as a drunkard uses a lamp post-for support rather than illumination.

Greg Mankiw

If we have a correct theory but merely prate about it, pigeonhole it and do not put it into practice, then that theory, however good, is of no significance.

Mao Zedong

The art of writing is mysterious; the opinions we hold are ephemeral , and I prefer the Platonic idea of the Muse to that of Poe, who reasoned, or feigned to reason, that the writing of a poem is an act of the intelligence. It never fails to amaze me that the classics hold a romantic theory of poetry, and a romantic poet a classical theory.

Jorge Luis Borges

Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience.

Neil deGrasse Tyson

There is no greater way to ensure that universities remain a hotbed of leftist thought than to guarantee that professors knight their own successors. But that's basically how the Ph.D. system works, with sitting professors approving the work of would-be professors.

Ben Shapiro

In order to displace a prevailing theory or paradigm in science, it is not enough to merely point out what it cannot explain; you have to offer a new theory that explains more data, and do so in a testable way.

Michael Shermer

Culture is an instrument wielded by professors to manufacture professors, who when their turn comes will manufacture professors.

Simone Veil

The possibility that stock value in aggregate can become irrationally high is contrary to the hard-form "efficient market" theory that many of you once learned as gospel from your mistaken professors of yore. Your mistaken professors were too much influenced by "rational man" models of human behavior from economics and too little by "foolish man" models from psychology and real-world experience.

Charlie Munger

Men who hold a theory of the Church which excludes from communion those whom they admit to have the Spirit of Christ simply proclaim that their theory is in flat contradiction to the spiritual fact.

Roland Allen

To construct a scientific theory from the data and to be able to recognize that it is a reasonable theory is possible only if there are some very sharp restrictive principles that lead you to go in one direction and not in another direction. Otherwise, you wouldn't have science at all, merely randomly chosen hypotheses.
