Some people set up a false either-or dichotomy to simplify their argument or their world view. The truth of the matter (as Asimov explains) is that we inhabit a both-and experience.
“How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.”
Belief in belief is merely belief, not proof. Asimov explains what he believes in.
“I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”
Forcing another to adopt your belief is tyranny. Forcing your religion upon another is religious tyranny. Insisting that your religion govern others who do not have any investment in belief in your religion is abhorrent. Unfortunately there are unqualified people out there who want to insist you believe the way they do.
“Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.”
