I am no chemist. My efforts in high school were absurd (and so was my teacher). But I understood enough to see the chemistry here not just as chemistry – because it was still that. Levi clearly has a high regard for his own vocation as a chemist. But it’s also (and this element was more accessible to me) chemistry as metaphor. The ability to control, transform, analyze, indeed to be rational, when all around you is anything but (i.e., WW2). Science, here, in contrast perhaps to any sense of a deity, is dependable, both in the form of its sometimes monotonous practice and in content. There are rules, laws here – not even a fascist can deny them. Therefore, there is freedom, at least in the mind.
It’s a tough book to classify, which is okay by me. Levi considered it a “micro-history.” I don’t have that category, and since I don’t think it would fit anything else, I did the best I could.
