Quote:
Every event must have a cause, and that cause, in turn, must have a cause, and so on. If there were no end to this backward progression of causes and effects, then their succession would be infinite. But an infinite series of causes and effects is unintelligible. Hence, there must be a first cause which is itself uncaused.
