Someone once said that "but" is a word that means, "forget everything that I have said up to this point; here comes the real scoop."
I strongly--strongly--believe in logic; and in all areas of my life. (I do not divide my brain into two different parts: one rational, and the other supra-rational. I have only the former.)
One component of logic is the existence of logical fallacies. And one of these fallacies is known as the a priori fallacy. (Basically, it just means to believe in a doctrine so thoroughly--without any supporting evidence--that one cannot possibly be convinced of the contrary.)
I never wish to be guilty of this--or any other form of logical fallacy.
I totally reject blind faith. Either faith must be based upon reason (as in, I have faith that my car will start tomorrow--as it always has), or else it is meaningless to me.
