The typical human problem, and one whose answer religion aims to supply, is always of the following form: Should I do this? Should we do this? Should the government do this? To answer this question we can resolve it into two parts: First — If I do this, what will happen? — and second — Do I want that to happen? What would come of it of value — of good?
Now a question of the form: If I do this, what will happen? is strictly scientific. As a matter of fact, science can be defined as a method for, and a body of information obtained by, trying to answer only questions which can be put into the form: If I do this, what will happen? The technique of it, fundamentally, is: Try it and see. Then you put together a large amount of information from such experiences. All scientists will agree that a question — any question, philosophical or other — which cannot be put into the form that can be tested by experiment … is not a scientific question; it is outside the realm of science.
I claim that whether you want something to happen or not — what value there is in the result, and how you judge the value of the result (which is the other end of the question: Should I do this?), must lie outside of science because it is not a question that you can answer only by knowing what happens; you still have to judge what happens — in a moral way. So, for this theoretical reason I think that there is a complete consistency between the moral view — or the ethical aspect of religion — and scientific information. – Richard Feynman
