 Philo, however, moves quickly away from chipping at the argument’s strength to questioning the intelligibility of its conclusion. We have no experience of the origin of a universe. Since causal inference requires a basis in experienced constant conjunction between two kinds of things, how can we legitimately draw any conclusion whatsoever about the origin of the universe? Does it even require a cause? One or many? Does the cause of the universe itself require a cause? The problem, then, is not just that the analogy is weak; the real problem is that it attempts to take us beyond what we can know.
