This is pure rationalism.

Socrates was dying, and somebody asked, ”Are you not afraid, Socrates?” He said, ”Why should I be afraid, because I don’t know what is going to happen? First thing, maybe atheists are right.”
Listen.
He says, ”Maybe, perhaps, atheists are right and I will simply disappear. Then there is nobody left, so why fear? For whom to fear? There cannot be any anguish for me, because I will not be there. If atheists are right, then I will not be, and when I am not, fear cannot exist. I will not be tortured. Or maybe theists are right and I may continue, and if I continue, then why fear? I will be there. So I will see what happens, but I have not died yet. Wait, let me die. Only then will I know whether I survive or not.”
This is pure rationalism. A rationalist cannot assert such things, that ”I don’t believe in a soul.”

RATIONALIST AND ATHEIST?

A person cannot be both together – a rationalist and an atheist. It is impossible. Either you can be a rationalist or you can be an atheist. A rationalist cannot believe in anything. A rationalist cannot have any belief – in God or in no God. A rationalist suspends all belief. A rationalist can only be an agnostic; he can only say, ”I do not know.”
The moment you say ”I know,” you are no longer a rationalist. The moment you say ”I know that God does not exist,” you are as irrational as the person who says God exists. You have lost track.
How can you say God is not?
The whole existence has not yet been measured. There are depths upon depths, there is much still unknown. A little is known. Far more remains unknown and unknowable. How can you say dogmatically that God is not?
A rationalist will avoid all temptation of dogmatism. He will say, ”I do not know.” Socrates was a rationalist, but he was not an atheist.
Atheism means you are against theism; you have chosen a belief. To believe in God is a belief; to believe in no God is a belief again. You remain a believer.
To be a rationalist is very difficult, arduous, because man wants to cling to some belief.
