"Real" What do we mean by that word? I ask a friend whether Pegasus exists, she says "no"...then I ask what it is to which I'm referring, and she says "Pegasus". So, if I'm referring to it then there must be some "it" to which I'm referring. At this point, my friend says "the concept of Pegasus exists, but Pegasus isn't real". Does that just mean that there is no physical construct which meets the criteria of the "concept of Pegasus"? Many Idealist philosophers have said that we have a "natural" perception of the world that is not bounded by physicalism until after we are taught it...in other words, we are indoctrinated into a Physicalist world-view, though this goes against our natural inclination. Yet, the "Pegasus" example seems to bare out the opposite conclusion. Are we naturally biased toward Physicalism? If so, why?
