In my opinion, neither organisms nor organizations evolve slowly and surely into something better, but drift until some small change occurs which has immediate and overwhelming significance. The special role of the human being is not to wait for these favorable accidents but deliberately to introduce the small change that will have great significance. To treat young men like men; to use modern recording techniques to capture the moment of exciting teaching; to gather ninety great men out of our one-hundred and seventy million — these, in retrospect, will seem like small changes indeed if they succeed in building a generation of greatness.

There's a tremendous popular fallacy which holds that significant research can be carried out by trying things. Actually it is easy to show that in general no significant problem can be solved empirically, except for accidents so rare as to be statistically unimportant. One of my jests is to say that we work empirically — we use bull's eye empiricism. We try everything, but we try the right thing first!
Who can object to a monopoly when there are several thousands of them? Who can object to a monopoly when every few years the company enjoying the monopoly revises, alters, perhaps even discards its product, in order to supply a superior one to the public? Who can object to a monopoly when any new company, if it is built around a scientific nucleus, can create a new monopoly of its own by creating a wholly new field?
Our society is changing so rapidly that none of us can know what it is or where it is going. All of us who are mature feel that there are historic principles of behavior and morality, of things that we all believe in that are being lost, not because young people couldn't believe in them, but because there is no language for translating them into contemporary terms. The search for that language, the search for the ways to tell young people what we know as we grow older — the permanent and wonderful things about life — will be one of the great functions of this system. We are losing this generation. We all know that. We need a way to get them back.
I think we must say this to each department: "Sharpen up the edges of ideas for the students in fields other than your own. They will not have years in which to find out what you meant, years during which they might achieve a sense of rich insight into your domain. But they are intelligent, they are earnest in their own department; they will profit all their lives from one year of brilliant teaching."
In thinking about what the human animal might have gone through in the evolutionary process, have you wondered how some of the small changes which must have occurred could have had survival value? Haven't you wondered how they could have survived, when, in all of our experimental work every small change we make dies? … How many changes must have occurred in the human eye, occurred and died, before one change came along — an apparently trivial change … that gave the whole animal a significant increase in its power to perceive and hunt down its enemies and find its food. This is the kind of change that survives.
An essential aspect of creativity is not being afraid to fail. Scientists made a great invention by calling their activities hypotheses and experiments. They made it permissible to fail repeatedly until in the end they got the results they wanted. In politics or government, if you made a hypothesis and it didn't work out, you had your head cut off.
