I am not trying to argue at this point for infinity of the mind although that could also be true in some sense but mainly I am trying to point out that mind may in fact be largely a non-physical existence. And if it were so equoating it with the size of its physical vehicle wouldnt make much sense.You can't easily measure the capacity of the mind (for thought, reason, emotion, etc.) but it is surely finite. If it weren't a human could continue learning and learning and never forget anything. Yet this is demonstrably false.
