Is that futile? By the way, Leibniz also discovered the
differential calculus. And coordinate geometry is due
to Descartes. Ultimately, all branches of knowledge
can legitimately be viewed as specialised subdivisions
of philosophy, both because it is the study of the
principles that underly them, and also because,
historically, they developed from it. You can say that,
now they've branched off, nothing useful is left in it,
but to do that convincingly you'd have to demonstrate
rather a good knowledge of it.
