"The conclusion seems to be irresistible that such laws of nature as the principle of conservation of energy, the principle of conservation of momentum and the law of gravitation are necessary consequences of our modes of measurement. They are, in fact, elaborately disguised identities which could have been predicted a priori by a being of sufficiently powerful analytical insight who fully understood all that is implied in the way we measure space-time intervals."

“Man is what he is, because a spiritual element has entered into, and taken possession of, animal consciousness. This spiritual element is not, according to Christian teaching, divine: but it is capable of entering into relations with God. It can perceive Him: in thought, it can reason as to His nature and actions: in will and feeling, it can serve and love Him, or disobey and fear Him. Such activity shows itself in what we call the working of conscience.”

“Spiritualism and the Christian Faith”

“Revelation can be supplemented by reason. Christ Himself gave reasons for His belief, and put in modern form, these reasons are, to my mind, conclusive. You remember the passage in the earliest Gospel: "But as touching the dead, that they are raised; have ye not read in the book of Moses, in the place concerning the bush, how God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? He is not the God of the dead, but of the living: ye do greatly err" Herein, in a form adapted to Jewish thought is "the one great argument which has made most sincere believers in God believers in Immortality also.”

“The astonishing thing about Einstein's equations is that they appear to have come out of nothing.”
