Charles Taylor, 1991:

"The importance of dialogical action in human life shows the utter inadequacy of the monological subject of representations which emerges from the epistemological tradition. We cannot understand human life merely in terms of individual subjects, who frame representations about and respond to others, because a great deal of human action happens only insofar as the agent understands and constitutes himself or herself as integrally part of a 'we.'
Much of our understanding of self, society, and world is carried in practices that consist in dialogical action. i would like to argue, in fact, that language itself serves to set up spaces of common action, on a number of levels, intimate and public. This means that our identity is never simply defined in terms of our individual properties. It also places us in some social space."
