“Time, the human dimension, which makes us everything we are.”

“It is only great pain--that slow, sustained pain that takes its time, in which we are, as it were, burned with smoldering green firewood--that forces us philosophers to sink to our ultimate profundity and to do away with all the trust, everything good-natured, veil-imposing, mild and middling, on which we may have previously based our humanity. I doubt that such a pain makes us 'better'--but I know that it makes us deeper.”

“When we deny the spiritual dimension to our existence, we end up living like animals. And when we deny the physical, sexual dimension to our existence, we end up living like angels. And both ways are destructive, because God made us human.”

“We are always getting away from the present moment. Our mental existence, which are immaterial and have no dimensions, are passing along the Time-Dimension with a uniform velocity from the cradle to the grave.”

“For string theory to make sense, the universe should have nine spacial dimensions and one time dimension, for a total of ten dimensions.”

“We live on a minute island of known things. Our undiminished wonder at the mystery which surrounds us is what makes us human. In science fiction we can approach that mystery, not in small, everyday symbols, but in bigger ones of space and time.”
