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.
I am on the edge of mysteries and the veil is getting thinner and thinner.
Interpretation
What this quote means
This quote suggests that we are close to uncovering profound truths and insights about the world.
Louis Pasteur's quote highlights the notion that humanity is continually approaching the boundaries of knowledge, where the unknown becomes more accessible. The 'edge of mysteries' alludes to the vast unexplored areas of science and life, while the 'veil getting thinner' symbolizes the gradual unveiling of these truths as we advance in our understanding and capabilities. Pasteur, a pioneer in microbiology, suggests an optimistic view of the scientific journey—the more we learn, the more we can uncover, bringing us closer to understanding the complexities 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.
These three things-work, will, success-fill human existences. Will opens the door to success, both brilliant and happy. Work passes these doors, and at the end of the journey success comes in to crown one's efforts.

It would be wrong to assume that one must stay with a research programme until it has exhausted all its heuristic power, that one must not introduce a rival programme before everybody agrees that the point of degeneration has probably been reached.
When I was 16 years old, I assembled a 2.3 million electron volt beta particle accelerator. I went to Westinghouse, I got 400 pounds of translator steel, 22 miles of copper wire, and I assembled a 6-kilowatt, 2.3 million electron accelerator in the garage.
