“The consequences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed.”

“Prediction is very difficult, especially about the future.”

“The future is the result of actions, and actions are the result of behavior, and behavior is the result of prediction.”

“The purpose of a thought-experiment, as the term was used by Schrödinger and other physicists, is not to predict the future - indeed Schrödinger most famous thought experiment goes to show that the "future," on the quantum level, cannot be predicted - but to describe reality, the present world.Science fiction is not predictive; it is descriptive.Predictions are uttered by prophets (free of charge), by clairvoyants (who usually charge a fee, and are therefore mor honored in their day than prophets), and by futurologists (salaried). Prediction is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.

“So long as we are brave enough to accept the consequences of our actions, no one can take away our freedom of choice.”

“Of all my children, you were always the hardest on yourself. You were always looking for the right way to behave, so concerned you might make a mistake. But, darling, there are no mistakes. There are only our wishes, our actions, and the consequences that follow both. There are only events, how we cope with them, and what we learn from the coping.""That's too easy," he said."On the contrary. It's monumentally difficult.”
