What is the position of imaginary cheese in thingspace, relative to the position of the cheese similarity cluster?
Along most dimensions (those relating to physical properties, most causal properties, etc.), imaginary cheese is quite far removed from actual cheeses. Along a couple of dimensions (verbal description, perhaps something like "what sorts of neutral firings are involved in perceiving it"), imaginary cheese is closer to actual cheeses.
To take a two-dimensional example, perhaps gouda is at (4,6), cheddar is (5,3), mozarella is (3,7), prov...
