The genuine creator creates something that has a life of its own, something that can exist and function without him. This is true not only of the writer, artist and scientist, but of creators in other fields...With the noncreative it is the other way around: in whatever they do, they arrange things so that they themselves become indispensable.

However human, envy is certainly not one of the sources of discontent that a free society can eliminate. It is probably one of the essential conditions for the preservation of such a society that we do not countenance envy, not sanction its demands by camouflaging it as social justice, but treat it, in the words of John Stuart Mill, as "the most anti-social and evil of all passions.

We shall assume that what each man does is based not on direct and certain knowledge, but by pictures made by himself or given to him. If his atlas tells him the world is flat he will not sail near what he believes to be the edge of our planet for fear of falling off.

In my childhood we were always assured that the brain was a telephone switchboard. ('What else could it be?') I was amused to see that Sherrington, the great British neuroscientist, thought that the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electro-magnetic systems. Leibniz compared it to a mill, and I am told some of the ancient Greeks thought the brain functions like a catapult. At present, obviously, the metaphor is the digital computer.

The history of science knows scores of instances where an investigator was in the possession of all the important facts for a new theory but simply failed to ask the right questions.
