Mario Augusto Bunge (/ˈbʊŋɡeɪ/ BUUNG-gay;[4] Spanish: [ˈmaɾjo ˈβuŋxe]; September 21, 1919 – February 24, 2020) was an Argentine-Canadian philosopher and physicist.

[1]: 1–2  Mario, who was the couple's only child, was raised without any religious education, and enjoyed a happy and stimulating childhood in the outskirts of Buenos Aires.

[1]: 1–22 Bunge had four children: Carlos Federico and Mario Augusto Julio, with ex-wife Julia Delfina Molina y Vedia,[3] and Eric R. and Silvia A., with his wife of over 60 years, the Argentine mathematician Marta Cavallo.

[1]: 413 Bunge began his studies at the National University of La Plata, graduating with a PhD in physico-mathematical sciences in 1952.

[12][13] Bunge defined himself as a left-wing liberal and democratic socialist, in the tradition of John Stuart Mill and José Ingenieros.

[20] He was critical of the ideas of well known scientists and philosophers such as Karl Popper, Richard Dawkins, Stephen Jay Gould, and Daniel Dennett.

[10] Bunge appreciated some aspects of Popper's critical rationalism but found it insufficient as a comprehensive philosophy of science,[21] and instead formulated his own account of scientific realism.
