“The human spirit must prevail over technology.”

“It has become appallingly obvious that our technology has exceeded our humanity.”

“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.”

“Every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe-a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble.”

“Laws alone can not secure freedom of expression; in order that every man present his views without penalty there must be spirit of tolerance in the entire population.”

“Technological progress is like an axe in the hands of a pathological criminal.”

“More and more I come to value charity and love of one's fellow being above everything else...All our lauded technological progress-our very civilization-is like the axe in the hand of the pathological criminal.”
