Rafael Squirru's essays, which include art and literary criticism, humanistic reflections and his philosophy of life, occupy the bulk of his writings. In his characteristic prose style -clear and concise- his essays were published in daily La Nación and journals such as the OAS Americas, Criterio, Primera Plana, Lyra, and Confirmado.
Compiled into several volumes, some of these were newly published as books under such titles as Ángeles y Monstruos, Exigencias del arte, El artista y su tiempo, Arte y humanismo, Libros y libros, cuadros y cuadros.
His more extensive essays on writers, artists and artistic movements constitute the contents of his prose works Claves del arte actual, Filosofía del arte abstracto and all those dedicated to individual artists and writers, like the Dead Weight series (Antonio Berni, Guillermo Roux, Luis Seoane, Juan Carlos Liberti, Aldo Severi), the Gaglianone series (Héctor Giuffré, Eduardo Mac Entyre, Juan del Prete, Miguel Ocampo, Kenneth Kemble), and Leopoldo Marechal (Ediciones Culturales Argentinas, 1961).
