Open Discussion: what boundaries exist between philosophy and other disciplines?

This meeting will be a live discussion of the title topic. This sort of discussion can't be settled in any particular way, but remains relevant for beginners and initiates to philosophy.

Here are some questions and comments that may help guide the conversation (feel free to bring questions of your own, as well):

When a given science makes a particular claim, what can philosophy state about it? Can philosophers make statements about the sciences without also understanding the details of those sciences, or is it restricted to certain peripheral claims?

Should philosophy itself be thought of as a science in its own right, or should it be something else (this may require an investigation of how we understand 'science')? What makes philosophy distinct from other disciplines?

Is philosophy a necessity for science, or is it the other way around? Is there some way in which they are mutually dependent?

Should all or some disciplines be seen as offshoots of philosophy? Is philosophy itself something that contains certain disciplines (metaphysics, epistemology, etc) or is this a confusion?

Can philosophy be separated from history and its developments?
