“For example, the GPLv2 in no way limits your use of the software. If you're a mad scientist, you can use GPLv2'd software for your evil plans to take over the world ("Sharks with lasers on their heads!!"), and the GPLv2 just says that you have to give source code back. And that's OK by me. I like sharks with lasers. I just want the mad scientists of the world to pay me back in kind. I made source code available to them, they have to make their changes to it available to me. After that, they can fry me with their shark-mounted lasers all they want.”

Generation of Greatness (1957)
Context: I believe there are two opposing theories of history, and you have to make your choice. Either you believe that this kind of individual greatness does exist and can be nurtured and developed, that such great individuals can be part of a cooperative community while they continue to be their happy, flourishing, contributing selves — or else you believe that there is some mystical, cyclical, overriding, predetermined, cultural law — a historic determinism.
The great contribution of science is to say that this second theory is nonsense. The great contribution of science is to demonstrate that a person can regard the world as chaos, but can find in himself a method of perceiving, within that chaos, small arrangements of order, that out of himself, and out of the order that previous scientists have generated, he can make things that are exciting and thrilling to make, that are deeply spiritual contributions to himself and to his friends. The scientist comes to the world and says, "I do not understand the divine source, but I know, in a way that I don't understand, that out of chaos I can make order, out of loneliness I can make friendship, out of ugliness I can make beauty."
I believe that men are born this way — that all men are born this way. I know that each of the undergraduates with whom I talked shares this belief. Each of these men felt secretly — it was his very special secret and his deepest secret — that he could be great.
But not many undergraduates come through our present educational system retaining this hope. Our young people, for the most part — unless they are geniuses — after a very short time in college give up any hope of being individually great. They plan, instead, to be good. They plan to be effective, They plan to do their job. They plan to take their healthy place in the community. We might say that today it takes a genius to come out great, and a great man, a merely great man, cannot survive. It has become our habit, therefore, to think that the age of greatness has passed, that the age of the great man is gone, that this is the day of group research, that this is the day of community progress. Yet the very essence of democracy is the absolute faith that while people must cooperate, the first function of democracy, its peculiar gift, is to develop each individual into everything that he might be. But I submit to you that when in each man the dream of personal greatness dies, democracy loses the real source of its future strength.
