Rationality does not suffice if one simply hasn't enough to reason with.
I don't see how superstition, twisting even that little, will help make a better decision.
Thing is: religionists co-opt everything that can, with any stretch of credibility, be classified as not rational.
But that's wrong.
Intuition doesn't belong to them.
Aesthetics do not belong to them.
Dreams and the subconscious do not belong to them.
Empathy does not belong to them.
Emotions do not belong to them.
The desire to form patterns does not belong to them.
The urge to tell stories does not belong to them.
The need to invent meaning and purpose does not belong to them.
Wonder does not belong to them.
They have co-opted these human attributes and served them very badly.
That's nothing to do with science, which isn't meant to, and doesn't pretend to do anything more than satisfy curiosity. They've set science up as an adversary, even though it never attacked them, because it
ignores them.
Satisfying curiosity fills all the human needs that are left over from work, friendship, marriage, art and sport.
Nobody needs religion.
They're terrified we'll all find out.
