“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.”

“The human spirit must prevail over technology.”

“Failure is success in progress”

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

“Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.”

“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.”
