More quotes by 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 me, for my experiments all stand forth to prove that spontaneous generation is a chimera.
Louis Pasteur
Outsidetheir laboratories, thephysicianand chemist are soldiers without arms on the field of battle.
Louis Pasteur
Do not promote what you can't explain, simplify, and prove early.
Louis Pasteur
Blessed is he who carries within himself a God, an ideal, and obeys it.
Louis Pasteur
After death, life reappears in a different form and with different laws. It is inscribed in the laws of the permanence of life on the surface of the earth and everything that has been a plant and an animal will be destroyed and transformed into a gaseous, volatile and mineral substance.
Louis Pasteur
The grandeur of the acts of men are measured by the inspiration from which they spring. Happy is he who bears a God within.
Louis Pasteur
Messieurs, c'est les microbes qui auront le dernier mot. (Gentlemen, it is the microbes who will have the last word.)
Louis Pasteur
There does not exist a category of science to which one can give the name applied science. There are sciences and the applications of science, bound together as the fruit of the tree which bears it.
Louis Pasteur
Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.
Louis Pasteur
Posterity will one day laugh at the sublime foolishness of the modern materialistic philosophy. The more I study nature, the more I stand amazed at the work of the Creator. I pray while I am engaged at my work in the laboratory.
Louis Pasteur
Did you ever observe to whom the accidents happen? Chance favors only the prepared mind.
Louis Pasteur
Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment.
Louis Pasteur
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.
Louis Pasteur
Worship the spirit of criticism. If reduced to itself it is not an awakener of ideas or a stimulant to great things, but, without it, everything is fallible it always has the last word.
Louis Pasteur
What did you do today to receive your instruction?
Louis Pasteur
Where are the real sources of human dignity, freedom and modern democracy, if not in the concept of infinity to which all men are equal?
Louis Pasteur
God grant that by my persevering labours I may bring a little stone to the frail and ill-assured edifice of our knowledge of those deep mysteries of Life and Death where all our intellects have so lamentably failed.
Louis Pasteur
Science knows no country because it is the light that iluminates the world
Louis Pasteur
No, there is now no circumstance known in which it can be affirmed that microscopic beings came into the world without germs, without parents similar to themselves. Those who affirm it have been duped by illusions, by ill-conducted experiments, spoilt by errors that they either did not perceive or did not know how to avoid.
Louis Pasteur
The more I know, the more nearly is my faith that of the Breton peasant. Could I but know all I would have the faith of a Breton peasant woman.
Louis Pasteur
