One of the goals for philosophers is to do this better than other people. It's not the only role, but it's one I take very seriously. In the beginning, it was all philosophy. It was philosophy. And as soon as that happens, those questions drop out of philosophy and become science.
Philosophy is the mother.
These are the offspring. We don't have to go back a long way to see traces of this. The eighteenth century is quite early enough to find the distinction between philosophy and physics not being taken very seriously. Psychology is one of the more recent births from philosophy, and we only have to go back to the late nineteenth century to see that. My sense is that the trajectory of philosophy is to work on very fundamental questions that haven't yet been turned into scientific questions.
