Welcome back to "Doggerel," where I ramble on about words and phrases that are misused, abused, or just plain meaningless.
One point that must sometimes be made over and over again is something quite simple: Science isn't some sort of ivory tower. It's a method. Scientists aren't all that special: They're just human beings who are supposed to have more experience with the scientific method. The fact that they're human means that they can make mistakes. They're subject to all the foibles of being human, which can include blind faith and wishful thinking.
That's why science focuses on the evidence: If you're going to say, for example, that Newton believed in alchemy, God, or whatever, you'd better be prepared to present his evidence. In fact, you should probably save some time by not bothering to mention Newton: The person who makes an argument is irrelevant to the validity of the argument. Newton's got a lot of well-deserved prestige, but that doesn't change the fact that he's made some poor arguments in his time.
Because I do my best to stay focused on the evidence, I typically remember experiments more readily than the scientists who performed them. About the only time I care about the scientists is when they've earned a reputation for sloppiness or dishonesty.
