On Free Will
“I have noticed that even people who claim everything is predetermined and that we can do nothing to change it, look before they cross the road.”
“Life would be tragic if it weren’t funny.”
On His IQ

On What He Think About All Day

His Advice to His Three Children

“God may exist, but science can explain the universe without a need for a creator.”
