Doctors Rejected Pasteur’s Work

Whether in science, or in entrepreneurship, at the initial stages of an important new idea, the majority of experts will reject the idea. So a key for the advance of science, or for innovation in the economy, is to allow scientists and entrepreneurs to accumulate sufficient resources so that they can make informed bets based on their conjectures, and on their tacit knowledge.
A few entries ago, Hager recounted how Leeuwenhoek faced initial skepticism from the experts. In the passage below, Hager recounts how Pasteur also faced initial skepticism from the experts:

(p. 44) If bacteria could rot meat, Pasteur reasoned, they could cause diseases, and he spent years proving the point. Two major problems hindered the acceptance of his work within the medical community: First, Pasteur, regardless of his ingenuity, was a brewing chemist, not a physician, so what could he possibly know about disease? And second, his work was both incomplete and imprecise. He had inferred that bacteria caused disease, but it was impossible for him to definitively prove the point. In order to prove that a type of bacterium could cause a specific disease, precisely and to the satisfaction of the scientific world, it would be necessary to isolate that one type of bacterium for study, to create a pure culture, and then test the disease-causing abilities of this pure culture.
