Taking him for all and all, I think it will be conceded that Michael Faraday was the greatest experimental philosopher the world has ever seen. - John Tyndall

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

[T]he enunciation of a thought in advance of the moment provokes dissent or evokes approval, and thus promotes action. The thought may be unwise; but it is only by discussion, checked by experience, that its value can be determined.

The logical feebleness of science is not sufficiently borne in mind. It keeps down the weed of superstition, not by logic but by slowly rendering the mental soil unfit for its cultivation.
