The Act Of Creation (public library) — a seminal treatise on creativity, penned by Hungarian-British journalist and author Arthur Koestler in 1964. In this magnificent 700-page tome, Koestler itemizes the principles of creativity — “the conscious and unconscious processes underlying scientific discovery, artistic originality, and comic inspiration” — and sets out to outline a common pattern that can be trained and perfected.

Koestler argues, there is one necessary condition for this combinatorial creative fusion — which he terms “bisociation” — to take place. In this passage from the end of Chapter V, he describes that condition beautifully, articulating the backbone of creativity:

Concerning the psychology of the creative act itself, I have mentioned the following interrelated aspects of it: the displacement of attention to something not previously noted, which was irrelevant in the old and is relevant in the new context; the discovery of hidden analogies as a result of the former; the bringing into consciousness of tacit axioms and habits of thought which were implied in the code and taken for granted; the uncovering of what has always been there.

‘It is obvious,’ says Hadamard, ‘that invention or discovery, be it in mathematics or anywhere else, takes place by combining ideas… . The Latin verb cogito for ‘to think’ etymologically means ‘to shake together.’ St. Augustine had already noticed that and also observed that intelligo means ‘to select among.’

The ‘ripeness’ of a culture for a new synthesis is reflected in the recurrent phenomenon of multiple discovery, and in the emergence of similar forms of art, handicrafts, and social institutions in diverse cultures. But when the situation is ripe for a given type of discovery, it still needs the intuitive power of an exceptional mind, and sometimes a favorable chance event, to bring it from potential into actual existence. On the other hand, some discoveries represent striking tours de force by individuals who seem to be so far ahead of their time that their contemporaries are unable to understand them.

Thus at one end of the scale we have discoveries which seem to be due to more or less conscious, logical reasoning, and at the other end those due to sudden insights which emerge from the creative mind or the unconscious. The same polarity of logic and intuition will be found to prevail in the methods and techniques of artistic creation. It is summed up by two opposite pronouncements: Bernard Shaw’s ‘Ninety per cent perspiration, ten per cent inspiration’, on the one hand, Picasso’s ‘I do not seek — I find’ (je ne cherche pas, je trouve), on the other.
