"We have usurped many of the powers we once ascribed to God. Fearful and unprepared, we have assumed lordship over the life or death of the whole world — of all living things. The danger and the glory and the choice rest finally in man. The test of his perfectibility is at hand. Having taken Godlike power, we must seek in ourselves for the responsibility and the wisdom we once prayed some deity might have."

Again, in our enterprises we present the singular spectacle of daring and deliberation, each carried to its highest point, and both united in the same persons; although usually decision is the fruit of ignorance, hesitation of reflection. But the palm of courage will surely be adjudged most justly to those, who best know the difference between hardship and pleasure and yet are never tempted to shrink from danger. In generosity we are equally singular, acquiring our friends by conferring, not by receiving, favours.
