[Serious] Generally speaking, is philosophy a worthwhile subject of study?

[vulcanlogician]

Of course it depends on what you mean by philosophy.  Logic and critical thinking, both useful, aren't ordinarily included under that rubric.

I tend to put those two things at the core of philosophy, as things that define philosophy.... differentiates it from "normal" kinds of investigation. Especially critical thinking. Philosophers often want to object to and/or justify things that are taken for granted. That's critical thinking on steroids.

Could you elaborate on what you meant by " Logic and critical thinking, both useful, aren't ordinarily included under that rubric.".... ?
