Abstract

Greco-Roman philosophers and historians frequently attempted to define the human being vis-á-vis other animals by isolating capacities, intellectual, physical, and emotional, judged unique to humans. The Stoic claim that only humans have a sense of shame because only humans are rational and therefore capable of emotions, which entail reasoning, was contradicted by other philosophers and naturalists who argued that some animal behaviors were analogous to behavior in humans that indicate shame. Ancient debates on both sides of the issue of animal emotions are paralleled in current philosophy and cognitive ethology employing anecdotal and anthropomorphizing arguments that mirror classical examples.
