For anyone interested,  Johnny-Dee over at Fides Quaerens Intellectum has started what appears to be a series of posts on everyone’s favorite idealist philosopher, Bishop George Berkeley.  For anyone confused, idealism is a metaphysical theory which denies the existence of matter and asserts that the only things that exist are minds (or spirits) and ideas.  It’s not as crazy as it sounds (or maybe it is), and it is a great way to mess with a friend’s head.  So head on over to FQI and check it out.  The topic begins with this post.
