ABSTRACT
From the mid-1850s, and especially following the publication of Darwin’s Origin of Species in 1859, evolutionary thought supplied an overarching integrating framework for fields of Psychological enquiry hitherto relatively distinct.1 Animal behaviour, child development, individual differences, physiological psychology, social psychology, psychopathology, emotion and the very nature of ‘Mind’ itself-all could be cast as facets of the single task of studying human psychology from an evolutionary perspective. Other cultural factors greatly facilitated this, notably growing governmental needs for techniques of ‘managing individuality’ in the expanding urban and industrialised societies.2 Also, as Morawski (1992a,b) points out, US culture was, at this time, psychologically confused at many levels, creating a situation in which Psychology both expressed and exploited the widefelt need for guidance in construing ‘subjectivity’ and what ‘human nature’ was really (i.e., scientifically) like.
