Simbolicità e emotività negli animali non umani: un tema attuale con radici lontane
Are the communication systems of non-human animals endowed with the property of symbolism or are they merely expressions of emotional states? The question has pervaded the philosophical debate at least since the time of Descartes and is now abundantly discussed in the field of cognitive ethology. In this paper, the topic is summarized both from the philosophical point of view (reconsidering Brentan’s notion of 'intentionality', often referred to by ethologists, too) and from the experimental point of view, referring to some well-known case-studies of the last decades.
