I can absolutely agree with that if you are staying well away from continental philosophy. Otherwise, your strict logical theory really stops at Kant (unless you consider Marx or Engles philosophers, which, perhaps). But really, fuck Bertrand Russel and all his bullshit.

I sometimes forget that logic and set theory is technically part of the philosophical canon visavis the Greeks, even though it was literally the part of my philosophy minor I did the best in. But yes, I suppose that is a natural path.

Idk though, I always had a teacher who would watch the PhD students try to use a new lemma they created on a philosophical problem, just sign, roll his eyes, and go "This is logic, not philosophy."
