A Quote by 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.

There are friends with whom we share neither interests nor any particular experiences, friends with whom we never correspond, whom we seldom meet and then only by chance, but whose existence nonetheless has for us a special if uncanny meaning. For me the Eiffel Tower is just such a friend, and not merely because it happens to be the symbol of a city, for Paris leaves me neither hot nor cold. I first became aware of this attachment of mine when reading in the paper about plans for its demolition, the mere thought of which filled me with alarm.
There is only one Art, whose sole criterion is the power, the authenticity, the revelatory insight, the courage and suggestiveness with which it seeks its truth. ... Thus, from the standpoint of the work and its worth it is irrelevant to which political ideas the artist as a citizen claims allegiance, which ideas he would like to serve with his work or whether he holds any such ideas at all.
The classical theorists resemble Euclidean geometers in a non-Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight as the only remedy for the unfortunate collisions which are occurring. Yet, in truth, there is no remedy except to throw over the axiom of parallels and to work out a non-Euclidean geometry.
Politics are vulgar when they are not liberalised by history, and history fades into mere literature when it loses sight of its relation to practical politics.
The work of mathematicians on 'pure' problems has often yielded ideas that have waited to be rediscovered by physicists. The work of Euclid, Apollonius and Archimedes on ellipses would be used centuries later by Kepler for his theory of planetary motion.
The concept of congruence in Euclidean geometry is not exactly the same as that in non-Euclidean geometry. ..."Congruent" means in Euclidean geometry the same as "determining parallelism," a meaning which it does not have in non-Euclidean geometry.
The work I was involved in had no obvious therapeutic benefit. It was purely of scientific interest. I hope the country will continue to support basic research even though it may have no obvious practical value.
I became startled by the extraordinary difference between something whose surface is completely invisible which only makes itself present by virtue of what it reflects, and a window, which doesn't make itself apparent at all, in the ideal case.
You have to have a lot of ideas. First, if you want to make discoveries, it's a good thing to have good ideas. And second, you have to have a sort of sixth sense-the result of judgment and experience-which ideas are worth following up. I seem to have the first thing, a lot of ideas, and I also seem to have good judgment as to which are the bad ideas that I should just ignore, and the good ones, that I'd better follow up.
Never since the dawn of human history, as far as I can find out, did people long settled in any region give a friendly welcome to newcomers. One of the disagreeable traits of our human nature seems to be to dislike on sight people who come later than the first settlers.
I thought this must be obvious to everyone else, as it seemed obvious to me; and that, if once it became apparent that we were on the edge, all the Great Powers would call a halt and recoil from the abyss.
A religion, that is, a true religion, must consist of ideas and facts both; not of ideas alone without facts, for then it would be mere Philosophy; - nor of facts alone without ideas, of which those facts are symbols, or out of which they arise, or upon which they are grounded: for then it would be mere History.
As man reaches out toward the twenty-first century, he will learn to be suspicious of all ideas that are not formulated so that they can be tested by observation. He will realize that the history of human thought shows that the ideas of which we are surest are the ones we most need to test. He will realize that his common sense only mirrors his training and experience. What seems natural and right to him is usually a reflection of the conditions under which he spent his first decade of life.
...the differential element of non-Euclidean spaces is Euclidean. This fact, however, is analogous to the relations between a straight line and a curve, and cannot lead to an epistemological priority of Euclidean geometry, in contrast to the views of certain authors.
You need people who have their own views, whose views you respect, whom you can have a productive disagreement with, and work out ideas which you might not have come up with, or who improve on ideas you had.
That the sight of people attracts still other people, is something that city planners and city architectural designers seem to find incomprehensible. They operate on the premise that city people seek the sight of emptiness, obvious order and quiet. Nothing could be less true. The presences of great numbers of people gathered together in cities should not only be frankly accepted as a physical fact... they should also be enjoyed as an asset and their presence celebrated.
