Katherine Hawley has rightly remarked that "analytic metaphysics is in resurgence; there is renewed and vigorous interest in topics such as time, causation, persistence, parthood and possible worlds".

The object of this thread is to discuss what metaphysics is (what topics it covers, what notions are most debated and by whom...) and also what justification we might have for preferring one metaphysical notion to another.

Here are a couple of resources which give the bakground to traditional metaphysics and to its revival in the last quarter of the 20th century :

Wikipedia (general introduction for the newcomer to metaphysics): http://en.wikipedia.org/wiki/Metaphysics

Stanford (for those who want an update on more recent trends): http://plato.stanford.edu/entries/metaphysics/

I'll try and regroup our earler debates on the various points under the new topic heading!
