This suggests that we must not think of ‘imagined turkeys’ or ‘turkeys in the understanding’ as kinds of turkey that can, in principle, be weighed against real ones but are always found to weigh less. Yet the ontological argument requires just this kind of comparison. It is here that it fails. For even if God only exists in imagination, like Dreamboat or the five-hundred-pound turkey, it does not follow that a greater being can be described or imagined. After all, the description had the superlatives put into it.
