About nLab Philosophy

nLab Philosophy is a page in the nLab wiki that gathers material on philosophy, with a focus on topics connected to mathematics and physics. It covers ontology, logic, the philosophy of mathematics, and the philosophy of physics, and it links to related entries, references, and books, articles, and talks.

The page places particular emphasis on higher category theory, homotopy type theory, and their possible implications for philosophy. Much of the content is in outline form, with scope notes, lists of topics, and open questions, and several sections state that they could be expanded. The page also states that general opinion essays on mathematics are outside its scope.
