G1/2 is a combination of Black's G1 and G2. Similarly for M1/2. G3 and M3 are Black's G3 and M3 with some inconsequential wording changes.

The question of how this premise is protected from the general knowledge that minds are not in fact physical regions is addressed in Barnden et al. (1994a). Our assumption that ``MIND PARTS AS PERSONS'' is a special case of ``MIND AS PHYSICAL SPACE'' is taken up again briefly in section 5.

How best to express vague degrees like "to some extent" is an important research problem within AI and other fields, one that we cannot address here. We will simply assume that some solution has been adopted.

This appears to be the same as the metaphor of ``A MIND IS A BODY MOVING IN SPACE'' discussed by Lakoff & Turner (1989, p.158).

By abduction we basically mean that if the system has a rule IF P THEN Q and has established Q then it can establish P tentatively. See, e.g., Hobbs et al. 1993, for a more sophisticated and practical notion of abduction.

We derived this example from ``The one thing that still troubled Marigold ... was the thought of her stepmother's arrival, and this hung over her mind like a dark angry cloud.'' (Jolly, n.d., p.44). Our example (12) is a simplified version of this passage designed to isolate the issue we wish to discuss. Note that the original passage uses a simile of thoughts being like clouds, but we regard this as a manifestation of a conceptual metaphor.

This is slightly inaccurate because a container is not just a physical region.
