Evidence is fact that discriminates between one theory and another. Facts do not speak for themselves. They speak for or against competing theories. Theories can be devastated by facts but they can never be proven correct by facts. What empirical verification can do is to reveal which of the competing theories currently being considered is more consistent with that which is known factually. Some other theory may come along tomorrow that is still more consistent with the facts, or explains those facts with fewer, clearer, or more manageable assumptions.
Physics is a good framework for thinking. ... Boil things down to their fundamental truths and reason up from there.
Extraordinary claims require extraordinary evidence.
I only believe in what I see and hear with my own eyes and ears.
Truth is the recognition of reality; reason, man's only means of knowledge, is his only standard of truth.
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.
Men of learning began to set experiments aside...to form theories...and to substitute these in the place of experiments.
Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom of thought; the positive results that come from doubting that all the lessons are true... Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.
If it disagrees with experiment, it's wrong.
What counts is not what sounds plausible, not what we would like to believe, not what one or two witnesses claim, but only what is supported by hard evidence rigorously and skeptically examined. Extraordinary claims require extraordinary evidence.
No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
Science is the most reliable guide for civilization, for life, for success in the world. Searching a guide other than the science is meaning carelessness, ignorance and heresy.
The good thing about science is that it is true whether or not you believe in it.
Science is more than a body of knowledge. It's a way of thinking: a way of skeptically interrogating the universe.
Nothing in Scientology is true for you unless you have observed it and it is true according to your observation.
The test of all knowledge is experiment.
Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.
Science is the only true guide in life.
Let not men think there is no truth, but in the sciences that they study, or the books that they read.
A soul might very well exist, but we, as physicists, try to measure and quantify everything. So far, no one has been able to create an experiment to do this for the soul. Efforts have been made to weigh the body after death, but each time we find no evidence of a soul. So a soul may very well exist, but it is not a testable theory.
More frightening than any particular beliefs or policies is an utter lack of any sense of a need to test those beliefs and policies against hard evidence. Mistakes can be corrected by those who pay attention to facts, but dogmatism will not be corrected by those who are wedded to a vision.
Science is the most reliable guide in life.
No amount of belief makes something a fact.
We have the right to our own opinions, but not our own facts.
I never once made a discovery ... I speak without exaggeration that I have constructed three thousand different theories in connection with the electric light ... Yet in only two cases did my experiments prove the truth of my theory.
