This seems like a poor curriculum rather than an actual flaw in philosophy, without the logic framework philosophy is just the history of ideas. If taught in a manner similar to math, where you learn logic tools and then build on top of them over time, I would expect similar and overlapping development.

A philosophy class teaching fundamentals in logic - taught in a way similar to math - is probably more like math in the sense of the article than philosophy in the sense of the grandparent post. The grandparent probably meant something more like a class on ethics, which doesn't really have the same style of beauty and truth that math does. This is certainly my impression after taking a few philosophy classes and a ton of math ones, including a philosophical logic class cross-listed with math.

This isn't a flaw of philosophy. Lots of fields of human study are great. Math just has some things that make it unique. But just like defining what art is, it's hard to pin down exactly what it all is.
