I think it is a bunch of poppycock. The world is as real and as spiritual to a street beggar as it is to a famous oil painter. Both just have differing perspectives and environments from which to draw thier perspectives from.

To say and/or to justify that one perspective is more real or more textured than another is to demean the others sense of reality.

The only truth in life is that which we create and is a self-justified reality.

Philosophy waxes over romantic often times and attempts to justify feelings of superiourity that are self-created. I am not sayinhg persay that philosophers are superiour-minded and yet this often seems to be the case. Lofty words and ideals often lend credence to this perspective.
