This seminal work by Étienne Bonnot de Condillac explores the profound relationship between humans and animals, not as a standalone issue but as a lens through which to understand the nature of the human mind.
Challenging the mechanistic view of animals proposed by Descartes and the ideas of Buffon, Condillac invites readers to reconsider what it truly means to be human. 
Beyond questions of animal treatment or rights, this treatise confronts the essential philosophical inquiry into human identity.
