Do you think Berkeleys idealistic metaphysics is supported or threatened by contemporary views of natural science?
I think it’s definitely threatened by all human experience including the natural sciences. Most natural scientists have moved to exactly the opposite epistemic position; i.e. materialism. While I disagree with both idealism and materialism and I hold that the truth lies somewhere in the middle (that is to say both ideas and matter exist) I don’t think anyone could rightly claim that modern science provides much support for Berkeley.
