Reason, Observation and Experience — the Holy Trinity of Science — have taught us that happiness is the only good; that the time to be happy is now, and the way to be happy is to help others to be so. This is enough for us. In this belief we are content to live and die. If by any possibility the existence of a power superior to, and independent of, Nature shall be demonstrated, we shall trust there will be time enough to kneel.
Until then, let us stand erect in this faith.
