“Concern for man himself and his fate must always constitute the chief objective of all technological endeavors...in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.”

“Shall a man go and hang himself because he belongs to the race of pygmies, and not be the biggest pygmie that he can? Let everyone mind his own business, and endeavor to be what he was made”

“Even in this world, more things exist without our knowledge than with it and the order in creation which you see is that which you have put there, like a string in a maze, so that you shall not lose your way. For existence has its own order and that no man's mind can compass, that mind itself being but a fact among others.”

“I believe in Spinoza's God, who reveals Himself in the lawful harmony of the world, not in a God who concerns Himself with the fate and the doings of mankind... to Rabbi Herbert Goldstein (1929)”

“He who is our Eternal Father has blessed you with miraculous powers of mind and body. He never intended that you should be less than the crowning glory of His creations.”

“Bless them that persecute you.' If our enemy cannot put up with us any longer and takes to cursing us, our immediate reaction must be to lift up our hands and bless him. Our enemies are the blessed of the Lord. Their curse can do us no harm. May their poverty be enriched with all the riches of God, with the blessing of Him whom they seek to oppose in vain. We are ready to endure their curses so long as they redound to their blessing.”
