Science adjusts its views based on what's observed Faith is the denial of observation so that belief can be preserved.
The test of a theory is its ability to cope with all the relevant phenomena, not its a priori 'reasonableness'. The latter would have proved a poor guide in the development of science, which often makes progress by its encounter with the totally unexpected and initially extremely puzzling.
Unlike mathematical theorems, scientific results can't be proved. They can only be tested again and again, until only a fool would not believe them. I cannot prove that electrons exist..........if you don't believe in them I have a high voltage cattle prod I'm willing to apply as an argument on their behalf. Electrons speak for themselves.
Our hypotheses are initially rooted in theoretical consistency and elegance, but...ultimatel y it is experiment not rigid belief that determines what is correct.
[T]he true natural sciences lock together in theory and evidence to form the ineradicable technical base of modern civilization. The pseudosciences satisfy personal psychological needs... but lack the ideas or the means to contribute to the technical base.
The more experiences and experiments accumulate in the exploration of nature, the more precarious the theories become. But it is not always good to discard them immediately on this account. For every hypothesis which once was sound was useful for thinking of previous phenomena in the proper interrelations and for keeping them in context. We ought to set down contradictory experiences separately, until enough have accumulated to make building a new structure worthwhile.
Experimental evidence is the final arbiter of right and wrong.
The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
Thoughts are but dreams till their effects are tried.
In mathematics we do not appeal to authority, but rather you are responsible for what you believe.
The art of drawing conclusions from experiments and observations consists in evaluating probabilities and in estimating whether they are sufficiently great or numerous enough to constitute proofs. This kind of calculation is more complicated and more difficult than it is commonly thought to be. . . .
Science doesn't purvey absolute truth. Science is a mechanism... for testing your thoughts against the universe.
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
We must conduct research and then accept the results. If they don't stand up to experimentation, Buddha's own words must be rejected.
Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not.
There's nothing wrong with raising venture capital. Many lean startups are ambitious and are able to deploy large amounts of capital. What differentiates them is their disciplined approach to determining when to spend money: after the fundamental elements of the business model have been empirically validated.
The function of Art is to disturb. Science reassures.
You don't believe that the Earth is round only if you're an astronaut. You don't believe Napoleon existed only if you're a historian. You believe these things because they're facts, proved by evidence.
Every theory in philosophy, which is built on pure conjecture, is an elephant; and every theory that is supported partly by fact, and partly by conjecture, is like Nebuchadnezzar's image, whose feet were partly of iron, and partly of clay.
The things of which we want the proof are those we know the best.
Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.
I’ve spent something like 17 years working on a theory for which there is essentially no direct experimental support.
Progress is achieved by exchanging our theories for new ones which go further than the old, until we find one based on a larger number of facts. ... Theories are only hypotheses, verified by more or less numerous facts. Those verified by the most facts are the best, but even then they are never final, never to be absolutely believed.
The problem of psychoanalysis is not the body of theory that Freud left behind, but the fact that it never became a medical science. It never tried to test its ideas.
I think that we shall have to get accustomed to the idea that we must not look upon science as a 'body of knowledge,' but rather as a system of hypotheses; that is to say, as a system of guesses or anticipations which in principle cannot be justified, but with which we work as long as they stand up to tests, and of which we are never justified in saying that we know they are 'true' or 'more or less certain' or even 'probable.'
