Has there ever been a religion with the prophetic accuracy and reliability of science? . . . No other human institution comes close.More Carl Sagan quotes [03/29/2018 05:03:36]
If we could travel into the past, it's mind-boggling what would be possible. For one thing, history would become an experimental science, which it certainly isn't today. The possible insights into our own past and nature and origins would be dazzling. For another, we would be facing the deep paradoxes of interfering with the scheme of causality that has led to our own time and ourselves. I have no idea whether it's possible, but it's certainly worth exploring.More Carl Sagan quotes [03/29/2018 05:03:36]
