To demonstrate experimentally that a microscopic organism actually is the cause of a disease and the agent of contagion, I know no other way, in the present state of Science, than to subject the microbe (the new and happy term introduced by M. Sédillot) to the method of cultivation out of the body.
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.
Interpretation
What this quote means
The quote reflects on the asymmetry of the universe and its influence on life, suggesting that our existence is shaped by the inherent irregularities in the cosmos.
In this quote, Louis Pasteur emphasizes the uniqueness and asymmetrical nature of the universe, positing that the intricacies of life are a direct result of this asymmetry. The imagery of the solar system illustrates how each celestial body moves in a distinct manner, creating a reality that cannot be perfectly mirrored or replicated, thus making life profoundly complex and diverse. Pasteur suggests that understanding this asymmetry is crucial to comprehending the essence of existence.

Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.

That's all that counts. People being sorry. Makes you feel better; gives you a sense of dignity, and that's all that's important; a sense of dignity. And it doesn't matter if you don't care or not, either. You got to have a sense of dignity, even if you don't care, 'cause, if you don't have that, civilization's doomed.
I believe there is something of the divine mystery in everything that exists. We can see it sparkle in a sunflower or a poppy. We sense more of the unfathomable mystery in a butterfly that flutters from a twig--or in a goldfish swimming in a bowl. But we are closest to God in our own soul. Only there can we become one with the greatest mystery of life. In truth, at very rare moments we can experience that we ourselves are that divine mystery.
