 Although Mario Bunge’s already classical book Causality (1959a) was a landmark in the study of causation, it was only several decades later that the interest on causation took off in the region. Eduardo Flichman developed a “deflationist” view of causation according to which causation is not an ontological relation between events but an anthropomorphic asymmetric relation that speakers project over reality. From this perspective, Flichman (1989) criticized the counterfactual theory of causation proposed by David Lewis (1973) by showing that clear cases of causation can be meaningfully reversed and, therefore, challenge the supposed asymmetry of causation.
