The nature of the relationship between ideas and the social conditions in which they develop has long been among the central concerns of fields like the sociology of knowledge, the sociology of intellectuals, and the social history of ideas. For generations, scholars in these areas have hotly debated the proper way of characterizing the form of this relationship and how it should be conceptualized and studied. With few exceptions, however, there has been an astonishing consensus on one matter: fundamental intellectual reorientations have almost invariably been seen as the product-whether simple or complex-of one or more major social changes. As far as it has gone, this perspective has led to extremely important conclusions, but except among the psychoanalytically inclined, it has remained strangely and regrettably silent on the specific micro-level processes by which macro-level social changes actually translate into changes in ideas.Through an analysis of the process that underlay the emergence of universalism during the Scottish Enlightenment, this study proposes a theoretical strategy to remedy that unfortunate state of affairs. The first section of the article sets the stage for the investigation by briefly describing the particularistic elements in early eighteenth-century Scottish Calvinist culture and how these gave way to a greater universalism in the writings of the enlightened intellectuals of the mid-eighteenth century. The second section outlines the principal transformations of eighteenth-century Scottish society that have previously been used to explain the Scottish Enlightenment. It then argues that to understand the process by which universalism emerged from the midst of such developments, one must go considerably beyond previous explanations and examine the experiences that the intellectuals of the Enlightenment encountered in micro-level social settings. There were many such settings, but following the lead provided in work on contemporary American society by Talcott Parsons (1959) 1 and especially Robert Dreeben (1968)-and refor-1 The text throughout will give the original publication date for cited materials unless there are special reasons for citing later editions.
