Mark, may I ask, then, what constitutes the "scientific method"? Isn't 
it the search for true propositions about nature? I mean: you got 
questions and want to have true answers to those questions. There are 
ways of obtaining those answers that are acknowledged in some community. 
But what you want is not just follow the procedures, you want the true 
answers.

That's right for sure: we might fail to know that an answer is true when 
we get it. But we will want to know. Not having questions to be answered 
would make sciences a childs game, playing around with elaborate toys 
following rules. And, Mark: success of a theory might be a hint that 
it's true.

Should we cross-post HOPOS?
