The Importance of Self-Help in Philosophy

When did philosophy turn from mainly being about moral experience and questions that are maybe even more fun but unanswerable? Is everything really here or is it just a hallucination? I mean, those kind of questions come and go. But there are still philosophers out there asking questions like, you know, why is there something rather than nothing? Or how do I know the world is real? So, yeah, if you were worried that they've gone away, they're still in university spending time thinking about those questions.
