No Doubt, Not Science
The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress, we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty--some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don't know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question--to doubt--to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained. - Richard P. Feynman * "The Value of Science," address to the National Academy of Sciences (Autumn 1955) Let me add that of all the scientific disciplines engineers are the most doubtful. Murphy is a constant companion. posted by Simon on 12.09.07 at 08:04 PM |

Wouldn't it be lovely if this was true of all laboring in the mines of science?
The postwarrior scientist whose research is in aid of legislation he desires demonstrates no uncertainty at all. He certainly does not doubt his intellectual and moral superiority to those he wishes to legally bully.
