it's more like philosophy is the dumping ground for stuff that we don't understand well enough to formalize and place in its own little box. that means that it changes with time. so there was a point when foundational issues in maths and logic were philosophy. the importance of frege, and then later peano, russel, etc, is that they were the ones that found a way to attack that set of problems, letting us isolate a chunk of knowledge as logic, set theory, etc. a similar process is probably happening now with consciousness - we're starting to develop the tools to answer questions that are currently "philosophical".
