This paper explores some philosophical questions regarding the tale “Conversation Among Oxen”, from Sagarana, of João Guimarães Rosa. Two philosophical questions are addressed. The first regards the carter Agenor Soronho ethics; the second is related to the narrative of Rodapião ox, which refers to knowledge theory and ontology.
