A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.
To be sure, Darwin's theory of evolution is imperfect. However, the fact that a scientific theory cannot yet render an explanation on every point should not be used as a pretext to thrust an untestable alternative hypothesis grounded in religion into the science classroom or to misrepresent well-established scientific propositions.
Theory is the essence of facts. Without theory scientific knowledge would be only worthy of the madhouse.
The theory of evolution, like the theory of gravity, is a scientific fact.
The fact that these scientific theories have a fine track record of successful prediction and explanation speaks for itself. (Which is not to say that I don't directly discuss the work of those philosophers who would disagree.) But even if we grant this, many will argue that scientific knowledge in humans, and, indeed, reflective knowledge in general, is quite different in kind from the knowledge we see in other animals.
Knowledge is theory. We should be thankful if action of management is based on theory. Knowledge has temporal spread. Information is not knowledge. The world is drowning in information but is slow in acquisition of knowledge. There is no substitute for knowledge.
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.
The crisis consists precisely in the fact that the old is dying and the new cannot be born
Society would not tolerate legislation declaring that the theory that the sun circles the earth be given equal time with the theory of a heliocentric solar system; it should not pay attention to the equally preposterous notions of scientific creationism
We have now the remarkable spectacle that just when many scientific men are agreed that there is no part of the Darwinian system that is of any great influence, and that, as a whole, the theory is not only unproved, but impossible, the ignorant, half-educated masses have acquired the idea that it is to be accepted as a fundamental fact.
Manliness consists not in bluff, bravado or loneliness. It consists in daring to do the right thing and facing consequences whether it is in matters social, political or other. It consists in deeds not words.
There is no scientific theory that could lead us from a detailed map of every single neuron in someone's brain to a conscious experience. We don't even have the beginnings of a theory whose conclusion would be "such a system is conscious.
But I think schools also ought to be fair to all views. Because, frankly, Darwinism is not an established scientific fact. It is a theory of evolution, that's why it's called the theory of evolution.
If the world kept a journal, many of the entries would be conversations concerning the advancement of scientific knowledge and its importance to humanity. I offer the following conversation as an added entry: "And what is as important as knowledge?" asked the mind. "Caring," answered the heart.
My provocative statement is that we desperately need a serious, scientific theory of cities and scientific theory means quantifiable, relying on underlying generic principles that can be made in a - put into a predictive framework. That's the quest.
Typically in science, individual scientists make up their minds about scientific fact or theory one at a time. We don't take votes. We just don't vote on quantum mechanics, the theory of relativity, why the sky is blue, or anything else.
