Louis Pasteur Quotes (1822-1895)

“The Greeks have given us one of the most beautiful words of our language, the word "enthusiasm" — a God within. The grandeur of the acts of men are measured by the inspiration from which they spring. Happy is he who bears a God within.”

“You bring me the deepest joy that can be felt by a man whose invincible belief is that Science and Peace will triumph over Ignorance and War, that nations will unite, not to destroy, but to build, and that the future will belong to those who will have done most for suffering humanity.”

“Every chemical substance, whether natural or artificial, falls into one of two major categories, according to the spatial characteristic of its form. The distinction is between those substances that have a plane of symmetry and those that do not. The former belong to the mineral, the latter to the living world.”

“The idea of God I an idea of the form of the infinite. As long as the mystery of the Infinite weighs heavily on human though, temples will be erected for the worship of the Infinite, whether God be called 'Brahma,' 'Allah,' 'Jehovah,' or 'Jesus'; and on the pavement of those temples men will be seen kneeling, prostrate, annihilated, in the thought of the Infinite.”

“He who proclaims the existence of the Infinite, and none can avoid it — accumulates in that affirmation more of the supernatural than is to be found in all the miracles of all the religions; for the notion of the Infinite presents that double character that forces itself upon us and yet is incomprehensible. When this notion seizes upon our understanding we can but kneel ... I see everywhere the inevitable expression of the Infinite in the world; through it the supernatural is at the bottom of every heart. The idea of God is a form of the idea of the Infinite. As long as the mystery of the infinite weighs on human thought, temples will be erected for the worship of the Infinite, whether God is called Brahma, Allah, Jehovah, or Jesus; and on the pavement of these temples, men will be seen kneeling, prostrated, annihilated by the thought of the Infinite.”

“[Berthelot] is not only a great chemist, but also a great philosopher. He possessed a universal spirit. His discovery of the synthesis of organic materials would be enough to immortalize his name. His work on explosive materials were also invaluable services...”

“In September 1873 the Germans, who had been occupying sixteen départements, finally left the country. Showing remarkable resilience, the French had discharged the entire five-billion-franc indemnity in a little more than two years. These reparations had been paid so promptly thanks largely to the profits from a booming wine industry, since Louis Pasteur had discovered that pasteurizing wine — briefly heating it to fifty-five degrees Celsius to kill off the microscopic organisms — made it last longer and travel better. The result was an increase in exports to countries such as Britain and America. French art as well as French wine looked like it was beginning to travel well.”

“Pasteur originally conceived the idea of germs and of destroying them. Although this started as a personal thing, it has mushroomed into DDT, killing beetles and worms, resulting in food contamination, much sickness, and trouble. Although he is regarded as hero by modern medicine, Pasteur will be treated in much the same way as a warmonger when he is judged in the spiritual world.”

“Pasteur was far ahead of his time. Although the structural theory of Kekulé had not yet been proposed, Pasteur explained his results by speaking of the molecules themselves, saying, “There is no doubt that [in the dextro tartaric acid] there exists an asymmetric arrangement having a nonsuperimposable image. It is no less certain that the atoms of the levo acid have precisely the inverse asymmetric arrangement.” Pasteur's vision was extraordinary, for it was not until 25 years later that his ideas regarding the asymmetric carbon atom were confirmed. Today, we would describe Pasteur's work by saying that he had discovered enantiomers. Enantiomers, also called optical isomers, have identical physical properties, such as melting point and boiling point, but differ in the direction in which their solutions rotate plane-polarized light.”
