“If you are religious, then remember that this bomb is Man's challenge to God. It's worded quite simply: We have the power to destroy everything that You have created. If you're not religious, then look at it this way. This world of ours is 4 600 000 000 years old. It could end in an afternoon.”

“You have many years to live—do things you will be proud to remember when you're old.”

“So do something that would have worked anyway whether God is real or not, and then simply assume that it worked because God is real. Of course. That’s religious logic for you.”

“Humans lived for several million years as fully wild beings: only in the last 10, 000 did we invent agriculture; only in the last couple of centuries did we invent industry. We are a species that has spent 99 per cent of its history as hunter-gatherers. We haven't had time for our unconscious minds and our unconscious needs to have changed. If you like, our souls have not changed, and this is true whether or not we believe that we have them.”

“If you and I are to live religious lives, it mustn't be that we talk a lot about religion, but that our manner of life is different. It is my belief that only if you try to be helpful to other people will you in the end find your way to God.”

“You have been allowing challenges to destroy you instead of you to destroy challenges. When challenges come – my God has the final say, not my ability or knowledge.”

“How can you become old in spirit? Only by carrying the past, isn't it? If you carry sixty years of burden with you, you're sixty years old. If you don't carry anything, you're like a newborn. The physical body may develop limitations, but the way you are has no limitations. It simply has no limitations. You are this many years old or that many years old simply because you carry that many years of garbage with you.”

“They say we have we created the man to end all wars; I say we have created a man to end all worlds.”

“The religious life, and all the agony that goes with it, is just something God sics on people who have the gall to accuse Him of having created an ugly world.”

“If you tell people you talk to God, they'll think you're religious, but if you say God talks to you, it's ten to one they'll think you're crazy.”
