Aristotelian rationality of animals: phantasia as a commonality of human and animal cognitive processes

Abstract

This dissertation investigates Aristotle’s theory of phantasia as a cognitive ability, in terms of which mental content is available to the mind of rational beings. The focus is on Catherine Osborne’s extension of phantasia to nonhuman animals in order to allow for and explain non-human animal behaviour in terms of a rational paradigm, which de-emphasises, and does not rely on, linguistic ability. This paradigm for understanding animal behaviour as rational supports, and is supported by, modern theories of cognitive ethology, and argues for the ability of animals to share in conceptual thought. The recognition of rationality in animals by means of this paradigm bears ethical consequences for the treatment of animals.
