Sergei Rubinstein
Thesis: this dossier situates theory within institutions, struggles, and concrete historical development.
Established HistorySergei Rubinstein (1889-1960) was a Soviet psychologist and philosopher known for the principle that psyche and activity are internally related. He argued that mental development emerges in practical engagement with objective conditions, making action under concrete circumstances central to analysis.
For materialist psychology, Rubinstein helps ground a non-dualist approach: neither pure internalism nor mechanical externalism is adequate. His work supports models where subjectivity is formed through reciprocal interaction between persons and historically structured environments.
