Superstition may be defined as constructive religion which has grown incongruous with intelligence.

Charles Darwin, the Abraham of scientific men - a searcher as obedient to the command of truth as was the patriarch to the command of God.

Religious feeling is as much a verity as any other part of human consciousness; and against it, on the subjective side, the waves of science beat in vain.

It is as fatal as it is cowardly to blink facts because they are not to our taste.
