"Reconnecting with a long, Pasteurian
family legacy, I am certain that our work together will open new horizons for tomorrow's medicine."
The speaker invokes the tropes of disease to describe the effects of affection: he refers to the "germs of Love" that attack the heart, the "fatal epidemic" that love precipitates, and his belief that "Pasteurian
art" has rendered him immune.
In later chapters he analyzes the medical debates surrounding Pasteur's evidence for microbes and vaccination and shows that the earlier views were still very much alive in the last decades of the century, mostly because, in the Pasteurian
model, the vectors of infection were so difficult to isolate or track that they could not easily serve as a basis for hygienic intervention.
