“It's for us that the University exists, for the dispossessed of the world; not for the students, not for the selfless pursuit of knowledge, not for any of the reasons that you hear. We give out the reasons, and we let a few of the ordinary ones in, those that would do in the world; but that's just protective coloration. Like the church in the Middle Ages, which didn't give a damn about the laity or even about God, we have our pretenses in order to survive. And we shall survive—because we have to.”

“We all like to think the world ends when we do. The truth is our acquaintances, our friends, and our loved ones all live on, and through them, so do we. It's not about what you had, but what you gave. It's not about how you looked, but how you lived. And it's not just about being remembered. It's about giving people a good reason to remember you.”

“... if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason - for then we would know the mind of God.”

“We have to choices in this world; we either try to survive or to give up.”

“This is the only time for high ideals because those ideals are all that we have. We aren't just fighting for our physical survival, but for the survival of our civilization. We don't have the luxury of old-world pillars. We don't have a common heritage, we don't have a millennia of history. All we have are the dreams and promises that bind us together. All we have...is what we want to be.”

“My only certainty in life is that I shall one day die. I can be certain of nothing else in the future. But either we survive (and so far in human history a vast majority has always survived) and having survived when we might not have done so gives us what we call happiness; or we do not survive and do not know it.”
