How does the once-unthinkable become not only thinkable but self-evident? How does the unthinkable become something we cannot think away anymore? To get at that, we have to tell a history not only of emergence, but of the formation of the deepest levels of our intuition. I have a strong sense that our best reasoning takes place at a semi-conscious level, and I’m very interested in how that lower stratum of reasoning — the intuitions that drive our thinking in philosophy, mathematics, and the rest — is established. – Los Angeles Review of Books
