José Ferrater Mora

José María Ferrater Mora (; 30 October 1912 – 30 January 1991) was a Spanish philosopher, essayist and writer. He is considered the most prominent Catalan philosopher of the 20th-century and was the author of over 35 books, including a four-volume ''Diccionario de filosofía'' (Dictionary of Philosophy, 1941) and ''Being and Death: An Outline of Integrationist Philosophy'' (1962). Subjects he worked on include ontology, history of philosophy, metaphysics, anthropology, the philosophy of history and culture, epistemology, logic, philosophy of science, and ethics. He also directed several films.

Ferrater Mora was known for his inclusion of humans and non-human animals within the same moral sphere, or continuum, arguing that the difference was one of degree, not kind. Provided by Wikipedia
