Arthur Koestler quotes

The more original a discovery, the more obvious it seems afterwards. (Arthur Koestler)
Creativity is a type of learning process where the teacher and pupil are located in the same individual. View quote
Arthur Koestler
The progress of science, like an ancient desert trail, is strewn with the bleached skeletons of discarded theories, doctrines, and axioms which seemed to possess eternal life. View quote
Arthur Koestler
Nothing is more sad than the death of an illusion. View quote
Arthur Koestler
In the social equation, the value of a single life is nil; in the cosmic equation, it is infinite... Not only communism, but any political movement which implicitly relies on purely utilitarian ethics, must become a victim to the same fatal error. It is a fallacy as naïve as a mathematical teaser, and yet its consequences lead straight to Goya's Disasters, to the reign of the guillotine, the torture chambers of the Inquisition, or the cellars of the Lubianka.

Without the hard little bits of marble which are called 'facts' or 'data' one cannot compose a mosaic; what matters, however, are not so much the individual bits, but the successive patterns into which you arrange them, then break them up and rearrange them. View quote
Arthur Koestler
If there is a lesson in our story it is that the manipulation, according to strictly self-consistent rules, of a set of symbols representing one single aspect of the phenomena may produce correct, verifiable predictions, and yet completely ignore all other aspects whose ensemble constitutes reality.

If time is treated in modern physics as a dimension on a par with the dimensions of space, why should we a priori exclude the possibility that we are pulled as well as pushed along its axis? The future has, after all, as much or as little reality as the past, and there is nothing logically inconceivable in introducing, as a working hypothesis, an element of finality, supplementary to the element of causality, into our equations. It betrays a great lack of imagination to believe that the concept of "purpose" must necessarily be associated with some anthropomorphic deity. View quote

The evolution of the brain not only overshot the needs of prehistoric man, it is the only example of evolution providing a species with an organ which it does not know how to use. View quote
Arthur Koestler
We find in the history of ideas mutations which do not seem to correspond to any obvious need, and at first sight appear as mere playful whimsies such as Apollonius' work on conic sections, or the non-Euclidean geometries, whose practical value became apparent only later. View quote
Arthur Koestler
God seems to have left the receiver off the hook, and time is running out. (Arthur Koestler)
Men cannot be treated as units in operations of political arithmetic because they behave like the symbols for zero and the infinite, which dislocate all mathematical operations. View quote
Arthur Koestler
The principal mark of genius is not perfection but originality, the opening of new frontiers. View quote
Arthur Koestler
A writer's ambition should be to trade a hundred contemporary readers for ten readers in ten years' time and for one reader in a hundred years' time. View quote

Look at this. Did you ever see a magazine called the New Musical Express? It turns out there is a pop group called The Police - I don't know why they are called that, presumably to distinguish them from the punks - and they've made an album of my essay The Ghost in the Machine. I didn't know anything about it until my clipping agency sent me a review of the record. View quote

True creativity often starts where language ends. View quote
Arthur Koestler
One may not regard the world as a sort of metaphysical brothel for emotions. View quote
Arthur Koestler
The principle that the end justifies the means is and remains the only rule of political ethics; anything else is just a vague chatter and melts away between one's fingers. View quote
Arthur Koestler
History had a slow pulse; man counted in years, history in generations. (Arthur Koestler)
Two half-truths do not make a truth, and two half- cultures do not make a culture. View quote
Arthur Koestler
A publisher who writes is like a cow in a milk bar. View quote
Arthur Koestler
Chemically induced hallucinations, delusions and raptures may be frightening or wonderfully gratifying; in either case they are in the nature of confidence tricks played on one's own nervous system. View quote
Arthur Koestler
[T]he evidence from anthropology concurs with history in refuting the popular belief in a Jewish race descended from the biblical tribe. From the anthropologist's point of view, two groups of facts militate against this belief: the wide diversity of Jews with regard to physical characteristics, and their similarity to the Gentile population amidst whom they live. Both are reflected in the statistics about bodily height, cranial index, blood-groups, hair and eye colour, etc. Whichever of these anthropological criteria is taken as an indicator, it shows a greater similarity between Jews and their Gentile host-nation than between Jews living in different countries. ...The obvious biological explanation for both phenomena is miscegenation, which took different forms in different historical situations: intermarriage, large-scale proselytizing, rape as a constant (legalized or tolerated) accompaniment of war and pogrom.
