Reality is a Shared Hallucination (1997)
I am still reading it, but already I see it unnecessarily engages in a postmodernist-like confusion of map and territory.> Yet you know sure as you were born that there's a broader world outside ... [you know a bunch of other things about reality] ... At this instant, reading by yourself, where do these realities reside? Inside your mind. Memory in a very real sense is reality.Bloom is absolutely right that memory is central to all this.  But it's a category error to say that just because your knowledge of reality is through memory, that memory is the only realitiy.Ok, it's logically possible there is no external reality, and all that exists is just my (Ratnapala's) memory.  But even then the distinction remains.  Then, the lying medium (memory) is real, but the content of those memories is not a reality.
