[16] And whereas a man can fancy shapes he never saw, making up a figure out of the parts of divers creatures, as the poets make their centaurs, chimeras and other monsters never seen, so can he also give matter to those shapes, and make them in wood, clay or metal. And these are also called images, not for the resemblance of any corporeal thing, but for the resemblance of some phantastical inhabitants of the brain of the maker. But in these idols, as they are originally in the brain, and as they are painted, carved moulded or molten in matter, there is a similitude of one to the other, for which the material body made by art may be said to be the image of the fantastical idol made by nature. (Hobbes, p 444)

I see you have, in fact, touched Hobbes. There has never been a political philosophy book that has so excited me at first and so let me down in the end.
