This book presents a new way to understand human-animal interactions. Offering a profound discussion of topics such as human identity, our relationship with animals and the environment, and our culture, the author channels the vibrant Italian traditions of humanism, materialism, and speculative philosophy. The research presents a dialogue between the humanities and the natural sciences. It challenges the separation and oppression of animals with a post-humanism steeped in the traditions of the Italian Renaissance. Readers discover a vision of the human as a species informed by an intertwining with animals. The human being is not constructed by an onto-poetic process, but rather by close relati ons with otherness. The human system is increasingly unstable and, therefore, more hybrid. The argument it presents interests scholars, thinkers, and researchers. It also appeals to anyone who wants to delve into the deep animal-human bond and its philosophical, cultural, political instances. The author is a veterinarian, ethologist, and philosopher. He uses cognitive science, zooanthropology, and philosophy to engage in a series of empirical, theoretical, and practice-based engagements with animal life. In the process, he argues that animals are key to human identity and culture at all levels.
