"We know this much, but there is much we don't know; perhaps in the future we may know it. And beyond that, there is a space which is going to remain unknowable forever."
They say, believe. I say, explore. They say, don't doubt; I say, doubt to the very end, till you arrive and know and feel and experience. Then there is no need to repress doubt; it evaporates by itself. Then there is no need for you to believe.
