“The innovator, however, must in the first place be discontented, he must doubt the value of what he is doing or question the accepted ways of doing it. And secondly, he must be prepared to take fresh paths, to venture into fields where he is by no means expert. This is true, at least, of major forms of innovation; they make it possible for other men to be expert, but are not themselves forms of expertise. Freud was not an expert psycho-analyst; before Freud wrote there was no such thing; he created the standards by which psycho-analysts are judged expert. Neither was Marx an expert in interpreting history in economic terms nor Darwin an expert in evolutionary biology. If a man is trained, purely and simply, to be expert and contented in a particular task he will not innovate; Freud would have remained an anatomist, Marx a philosopher, Darwin a field-naturalist.”

One Human Minute (1986)
Context: The book does not contain “everything about the human being,” because that is impossible. The largest libraries in the world do not contain “everything.” The quantity of anthropological data discovered by scientists now exceeds any individual’s ability to assimilate it. The division of labor, including intellectual labor, begun thirty thousand years ago in the Paleolithic, has become an irreversible phenomenon, and there is nothing that can be done about it. Like it or not, we have placed our destiny in the hands of the experts. A politician is, after all, a kind of expert, if self-styled. Even the fact that competent experts must serve under politicians of mediocre intelligence and little foresight is a problem that we are stuck with, because the experts themselves cannot agree on any major world issue. A logocracy of quarreling experts might be no better than the rule of the mediocrities to which we are subject. The declining intellectual quality of political leadership is the result of the growing complexity of the world. Since no one, be he endowed with the highest wisdom, can grasp it in its entirety, it is those who are least bothered by this who strive for power.

Variant: What I am saying is that it is not so much what man is that counts as it is what he ventures to make of himself. To make the leap he must do more than disclose himself; he must risk a certain amount of confusion. Then, as soon as he does catch a glimpse of a different kind of life, he needs to find some way of overcoming the paralyzing moment of threat, for this is the instant when he wonders who he really is - whether he is what he just was or is what he is about to be. Adam must have experienced such a moment.
