This is the dedication page of the first volume of Sorokin’s Social and Cultural Dynamics (1937). Peter and Sergei were Sorokin’s sons.
Few would disagree, I am sure, that there was something wonderful — authentic, deep, sincere — about Sorokin the person. And I feel this can be seen in his family and the Russian émigré milieu he and they moved in: their closest associates and friends.
