That said, one of the key aspects of Steven Pinker’s The Blank Slate that struck me (when I read it to ‘know my enemy’ better, and ended up learning some things) was his defence of evolutionary psychology against social constructionism. While post-WWII leftist theorists have seen assessments of human psychology based on genetics as being irredeemably tainted by association with Nazi eugenics, they often failed to apply the same logic to the association between their own ‘blank slate’ vision of humanity and the social engineering of Marxist regimes.6
