“I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.”

“Intelligent life on other planets? I'm not even sure there is on earth!”

“It is surely unreasonable to credit that only one small star in the immensity of the universe is capable of developing and supporting intelligent life. But we shall not get to them and they will not come to us.”

“But I've learned that intelligence alone doesn't mean a damned thing. Here in your university, intelligence, education, knowledge, have all become great idols. But I know now there's one thing you've all overlooked: intelligent and education that hasn't been tempered by human affection isn't worth a damn...Intelligence is one of the greatest human gifts. But all too often a search for knowledge drives out the search for love...Intelligence without the ability to give and receive affection leads to mental and moral breakdown, to neurosis, and possibly even psychosis.”

“Intelligence and love are not in separate compartments: love is rich in intelligence and intelligence is full of love.”

“hat a feeble thing intelligence is, with its short steps, its waverings, its pacings back and forth, its disastrous retreats! Intelligence is a mere instrument of circumstances. There are people who say that intelligence must have built the universe—why, intelligence never built a steam engine! Circumstances built a steam engine. Intelligence is little more than a short foot-rule by which we measure the infinite achievements of Circumstances.”
