“We cannot prove that life is meaningful and that God exists. But neither can we prove that love is better than hate, altruism than selfishness, forgiveness than the desire for revenge. We cannot prove that the hope is truer to experience than the tragic sense of life. Almost none of the truths by which we live are provable, and the desire to prove them is based on a monumental confusion between explanation and interpretation. Explanations can be proved, interpretations cannot. Science deals in explanation. Meaning is always a matter of interpretation. It belongs to the same territory as ethics, aesthetics and metaphysics. In none of these three disciplines can anything of consequence be proved, but that does not make them insignificant. To the contrary, they represent three of the greatest repositories of human wisdom.”
