Pasteur Louis Quotes & Sayings

Analogy cannot serve as proof. — Louis Pasteur

We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw (Pasteur), or as lock and key (E. Fischer). — Paul R. Ehrlich

The universe is an asymmetrical entity. I am inclined to believe that life as it is manifested to us must be a function of the asymmetry of the universe or of the consequence of this fact. The universe is asymmetrical; for if one placed the entire set of bodies that compose the solar system, each moving in its own way, before a mirror, the image shown would not be superimposable on the reality. — Louis Pasteur

Virulence appears in a new light which cannot but be alarming to humanity; unless nature, in her evolution down the ages (an evolution which, as we now know, has been going on for millions, nay, hundreds of millions of years), has finally exhausted all the possibilities of producing virulent or contagious diseases - which does not seem very likely. — Louis Pasteur

My opinion - nay more, my conviction- is that, in the present state of science, as you rightly say, spontaneous generation is a chimera ; and it would be impossible for you to contradict

But when it has been shown by the researches of Pasteur that the septic property of the atmosphere depended not on the oxygen, or any gaseous constituent, but on minute organisms suspended in it, which owed their energy to their vitality, it occurred to me that decomposition in the injured part might be avoided without excluding the air, by applying as a dressing some material capable of destroying the life of the floating particles. Upon this principle I have based a practice. — Joseph Lister

Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment. — Louis Pasteur

Cultivate your curiosity. Keep it sharp and always working. Consider curiosity your life preserver, your willingness to try something new. Second, enlarge your enthusiasm to include the pursuit to excellence, following every task through to completion. Third, make the law of averages work for you. By budgeting your time more carefully than most people you can make more time available. Does the combination of curiosity, enthusiasm, and the law of averages guarantee success Indeed it does not ... Success in the final analysis always involves luck or the element of chance. Louis Pasteur grasped this well when he said that chance favors the prepared mind. — John Hanley Jr.

A blanket could be used to cure the common cold. I mean, come on it's just common sense. A blanket is warm, and if a cold is what it's named, then a blanket would transform a cold into some nameless nonentity. Take that, Louis Pasteur. — Jarod Kintz

Whatever your career may be, do not let yourselves become tainted by a deprecating and barren scepticism, do not let yourselves be discouraged by the sadness of certain hours which pass over nations. Live in the serene peace of laboratories and libraries. Say to yourselves first : ' What have I done for my instruction ? ' and , as you gradually advance, 'What have I done for my country?' until the time comes when you may have the immense happiness of thinking that you have contributed in some way to the progress and to the good of humanity. But, whether our efforts are or not favoured by life, let us be able to say, when we come near the great goal, ' I have done what I could — Louis Pasteur

Great problems are now being handled, keeping every thinking man in suspense; the unity or multiplicity of human races; the creation of man 1,000 years or 1,000 centuries ago; the fixity of species, or the slow and progressive transformation of one species into another; the eternity of matter; the idea of a God unnecessary: such are some of the questions that humanity discusses nowadays. — Louis Pasteur

When you believe you have found an important scientific fact, and are feverishly curious to publish it, constrain yourself for days, weeks, years sometimes, fight yourself, try and ruin your own experiments, and only proclaim your discovery after having exhausted all contrary hypotheses. But when, after so many efforts you have at last arrived at a certainty, your joy is one of the greatest which can be felt by a human soul. — Louis Pasteur

As in the experimental sciences, truth cannot be distinguished from error as long as firm principles have not been established through the rigorous observation of facts. — Louis Pasteur

I propose to provide proof ... that just as always an alcoholic ferment, the yeast of beer, is found where sugar is converted into alcohol and carbonic acid, so always a special ferment, a lactic yeast, is found where sugar is transformed into lactic acid. And, furthermore, when any plastic nitrogenated substance is able to transform sugar into that acid, the reason is that it is a suitable nutrient for the growth of the [lactic] ferment. — Louis Pasteur

There are only two possible explanations as to how life arose: Spontaneous generation arising to evolution or a supernatural creative act of God ... There is no other possibility. Spontaneous generation was scientifically disproved 120 years ago by Louis Pasteur and others, but that just leaves us with only one other possibility ... that life came as a supernatural act of creation by God, but I can't accept that philosophy because I do not want to believe in God. Therefore I choose to believe in that which I know is scientifically impossible, spontaneous generation leading to evolution. — George Wald
