We are in the habit of visualizing man’s political and social history as a wild zigzag which alternates between progress and disaster, but the history of science as a steady, cumulative process, represented by a continuously rising curve, where each epoch adds some new item of knowledge to the legacy of the past, making the temple of science grow brick by brick toever greater height. Or alternately, we think in terms of “organic” growth from the magic-ridden, myth-addicted infancy of civilization, through various stages of adolescence, to detached, rational maturity.
In fact, we have seen that this progress was neither “continuous” nor “organic”. The philosophy of nature evolved by occasional leaps and bounds alternating with delusional pursuits, culs-de-sac, regressions, periods of blindness, and amnesia. The great discoveries which determined its course were sometimes unexpected by-products of a chase after quite different hares. At other times, the process of discovery consisted merely in the cleaning away of the rubbish that blocked the path…
All we know is that mental evolution – from cave-dwellers to spacemen – cannot be understood either as a cumulative, linear process, or as a case of “organic growth” comparable to the maturing of the individual; and that it would perhaps be better to consider it in the light of biological evolution, of which it is a continuation.
Evolution is known to be a wasteful, fumbling process characterized by sudden mutations of unknown cause, by the slow grinding of selection, and by the dead-ends of over-specialization and rigid inadaptability. “Progress” can by definition never go wrong; evolution constantly does; and so does the evolution of ideas, including those of “exact sciences”.
New ideas are thrown up spontaneously like mutations; the vast majority of them are useless crank theories, the equivalent of biological freaks without survival-value. There is a constant struggle for survival between competing theories in every branch of the history of thought.
The process of natural selection, too, has its equivalent in mental evolution: among the multitude of new concepts which emerge only those survive which are well adapted to the period’s intellectual milieu. When we call ideas “fertile” or “sterile” we are unconsciously guided by biological analogy.
Most geniuses responsible for the major mutations in the history of thought seem to have certain features in common; on the one hand scepticism, often carried to the point of iconoclasm, in their attitude towards traditional ideas, axioms, and dogmas, towards everything that is taken for granted; on the other hand, an open-mindedness that verges on naive credulity towards new concepts which seem to hold out some promisse to their instinctive gropings. Out of this combination results that crucial capacity of perceiving a familiar object, situation, problem, or collection of data, in a sudden new light or new context…
This act of wrenching away an object or concept from its habitual associative context and seeing it in a new context is, as I have tried to show, an essential part of the creative process. It is an act both of destruction and creation, for it demands the breaking up of a mental habit, the melting down, with the blow-lamp of Cartesian doubt, of the frozen structure of accepted theory, to enable the new fusion to take place.
Every creative act – in science, art or religion – involves a regression to a more primitive level, a new innocence of perception liberated from the cataract of accepted beliefs.

Roughly within the five generations from Canon Koppernigk to Isaac Newton, homo sapiens underwent the most decisive change in his history. The uomo universale of the Renaissance, who was artist and craftsman, philosopher and inventor, humanist and scientist, astronomer and monk, all in one, split up into his component parts. Art lost its mythical, science its mystical inspiration; man became again deaf to the harmony of the spheres. The Philosophy of Nature became ethically neutral, and ‘blind’ became the favourite adjective for the working of natural law…
As a result, man’s destiny was no longer determined from ‘above’ by a super-human wisdom and will, but from ‘below’ by the sub-human agencies of glands, genes, atoms, or waves of probability. This shift of the locus of destiny was decisive. So long as destiny had operated from a level of the hierarchy higher than man’s own, it had not only shaped his fate, but also guided his conscience and imbued his world with meaning and value. The new masters of destiny were placed lower in the scale than the being they controlled; they could determine his fate, but could provide him with no moral guidance, no values and meaning. A puppet of the Gods is a tragic figure, a puppet suspended on his chromosomes is merely grotesque.”
