  phantasia is a capacity for sensory representation that enables the representation of features and objects of various kinds that are not currently perceived by way of the senses. I shall argue that Aristotle assigns to that capacity a prominent role in the production of behav-iour, and in particular in the production of purposive locomotion, because he takes it to be able to do something that perception cannot do, which is to put an animal in cognitive contact with prospective situations.

reflection: |
  Aristotle is solving a problem Plato created. Once you separate the soul from the body — once you make the rational part the true self and demote appetite to something that needs to be governed — you face an immediate puzzle: how does a body actually move toward anything? Perception alone cannot do it, because perception only registers what is present. The animal that can only perceive is trapped in the now, reactive, not purposive. What gets the body moving toward a future state is *phantasia*, the capacity to represent what is not yet here, to hold a prospective situation before the soul as if it were already something to meet.
  
  This is a more generous account of imagination than the tradition usually remembers. Aristotle is not describing daydreaming or illusion; he is describing the cognitive machinery by which desire becomes locomotive, by which longing orients a body in space and time. What the soul lacks, what it represents as absent and therefore reaches toward — that is the engine. Lorenz is pointing at something uncomfortable inside this framework: the very structure of purposive life depends on a gap, a not-yet, a prospective object that keeps receding as the body moves. The animal moves because it does not have the thing. That condition does not resolve at the destination.
reflection_v0_3: |
  The hinge is the word "prospective" — not remembered, not imagined in the loose sense, but forward-facing: a cognitive grip on a situation that does not yet exist for the senses. Aristotle needs this because perception alone is too slow, too tethered to the present moment, to explain purposive movement. An animal that could only respond to what it currently perceives would be perpetually surprised by the world. Phantasia fills that gap by carrying the animal mentally into a scene it has not yet entered — and this is why Aristotle elevates it above mere sensory registration. Hillman would likely note that this "prospective" function is close to what he calls the soul's inherent futurity, its orientation toward what is not yet actual. The thought worth holding is that what guides us toward a goal may not be a plan but a felt image of the situation waiting at the end of the path.
