The life and work of Argentine philosopher and writer Héctor Pablo Agosti is almost unknown to contemporaries. His emphasis on culture, the role of intellectuals, and, eventually, his requirement of a new ideological hegemony as part of a broad-based social change, makes Agosti a modern thinker. Agosti offers a comprehensive critique of contemporary socio-economic relations, providing an in-depth analysis of the status and role of intellectuals as creators of a new ideological hegemony that will become an integral part of the social struggle. His revolutionary concept of new society is also reflected in his literary musings, which culminate in his concept of a "New Realism". The paper seeks to acquaint the reader with the key aspects of Agosti’s work, emphasising the topicality of his approach.
