I'll give my own dogmatic answer to the problem of metaphysics (I'm influenced here by less dogmatic professor Amie Thomasson). Philosophy in general and metaphysics especially proceeds in three stages: (1) Conceptual analysis allows us to find out about functions and meanings of our words and concepts, and then (2) Conceptual engineering allows us to redesign our words and concepts to fulfil their functions better, after which (3) Conceptual ethics consists in discussion about which purposes and functions we should want to have anyway.After discussing conceptual ethics we can go back to engineering part, or maybe we can either invent a wholly new concept, or discard an old one.
