The Apocrypha... ought to be bound up with all your Bibles; it contains much that is beautiful and wise, and there is in history nothing finer than the description of Eleazar's end.

To Principal Caird... imaging of the Unseen is of inestimable value. It furnishes an objective counterpart to religious emotion, permanent but plastic—capable of indefinite change and purification in response to the changing thoughts and …

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.

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.

The brightest flashes in the world of thought are incomplete until they have been proved to have their counterparts in the world of fact.

The mind of man may be compared to a musical instrument with a certain range of notes, beyond which in both directions we have an infinitude of silence.

Life is a wave, which in no two consecutive moments of its existence is composed of the same particles.

A point highly illustrative of the character of Faraday now comes into view.

The experimental researches of Faraday are so voluminous, their descriptions are so detailed, and their wealth of illustration is so great, as to render it a heavy labour to master them. The multiplication of proofs, necessary and …

Knowledge once gained casts a faint light beyond its own immediate boundaries.
