Louis Pasteur Science Quotations

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.

Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

There are no such things as applied sciences, only applications of science.

There is no such thing as a special category of science called applied science; there is science and its applications, which are related to one another as the fruit is related to the tree that has borne it.
