Arthur Koestler Quote
The earliest discovery of Pasteur, and for him the most exciting in all his life, was the asymmetry of molecules as a specific characteristic of living organisms-in other words, the fact that the molecules of living matter come in two varieties which, though chemically identical, are in their spatial structure like mirror images to each other-or like right and left gloves. 'Left-handed' molecules rotate polarized light to the left, 'right-handed' molecules to the right; life substances are thus 'optically active'. Why this should be so we still do not quite know; but it remains a challenging fact that 'no other chemical characteristic is as distinctive of living organisms as is optical activity'.

About Arthur Koestler
Having moved to Britain in 1940, he published his novel Darkness at Noon, an anti-totalitarian work that gained him international fame. Over the next 43 years, Koestler espoused many political causes and wrote novels, memoirs, biographies, and numerous essays. In 1949, Koestler began secretly working with a British Cold War anti-communist propaganda department known as the Information Research Department (IRD), which would republish and distribute many of his works, and also fund his activities. In 1968, he was awarded the Sonning Prize "for [his] outstanding contribution to European culture". In 1972, he was made a Commander of the Order of the British Empire (CBE).
In 1976, he was diagnosed with Parkinson's disease and in 1979 with terminal leukaemia. On 1 March 1983, Koestler and his wife Cynthia committed suicide together at their London home by swallowing lethal quantities of barbiturate-based Tuinal capsules.
