Yes, it's another round of that classic guessing game - Animal, Vegetable, Mineral, Abstract [or any combination thereof]. This effort - '03/'04 should address any queries, but then again, may just serve to confuse and baffle which some might say is the point of the game. Patience, integrity and a decent search engine may be useful ....
Physical representation? I think "physical incarnation" might be a better phrase. In the M&V sense, the AOTC is very definitely real. Indeed, perhaps it is a mistake to call it Abstract; I think what I really mean is that the AOTC is a human construct.
