Molecules and Literary Criticism
If you take a look at the progress of science, the sciences are kind of a continuum, but they’re broken up into fields. The greatest progress is in the sciences that study the simplest systems. So take, say physics — greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.
If a molecule is too big, you give it to the chemists. The chemists, for them, if the molecule is too big or the system gets too big, you give it to the biologists. And if it gets too big for them, they give it to the psychologists, and finally it ends up in the hands of the literary critic, and so on.
