PT and Extended Metaphors

Metaphors often extend far beyond a single proposition. In a particular discussion (or even over an extended period in a given culture) metaphors may be carried out so that one thing is described in considerable detail using vocabulary from another domain altogether. In terms of simulation, this means that the metaphorical simulation is carried out extensively so that we pretend in numerous ways that one thing really is another thing. For instance, the discussion of familiarizing metaphors lists a number of the ways in which time is spoken of as if it really is money in our language. These extended metaphors are also very common in science: when describing photons, for instance, a scientist might leap back and forth between several sets of elaborate simulations. In one context, photons might be assigned many of the properties of waves, and in another context, many of the properties of particles.

Extended metaphors--even in science--often involve the personification of objects or ideas. By applying vocabulary usually reserved for humans to non-human things, we pretend that feuding subatomic particles, vacuum-hating Nature, or obstinate laser printers have human characteristics. Let's consider PT's approach to one such extended, 'animistic' metaphor, in which like subatomic charges 'hate' one another, and opposite charges 'love' one another. Suppose that we've given PT the following metaphorical propositions:
