This paper is a speculative attempt to understand the nature of the "psychological" from the perspective of the 'social". Following in the tradition of Wundt's Völkerpsychologie, we borrow the notion of 'social character" from Erich Fromm, and the notion of "conventionality", as constitutive of the 'social order", from F. A. Hayek, to arrive at a social understanding of the psychological. From within this social perspective of the psychological, a hermeneutical conception of human science is proposed that interprets the social-psychological as a dialogical relationship between individual-psychological and social-cultural "prejudices".
