At the core of Unger's theoretical philosophy are two key conceptions: first the infinity of the individual, and secondly the singularity of the world and the reality of time. The premise behind the infinity of the individual is that we exist within social contexts but we are more than the roles that these contexts may define for us—we can overcome them. In Unger's terms, we are both "context-bound and context-transcending; "we appear as "the embodied spirit;" as "the infinite imprisoned within the finite." For Unger, there is no natural state of the individual and his social being. Rather, we are infinite in spirit and unbound in what we can become. As such, no social institution or convention can contain us. While institutions do exist and shape our beings and our interactions, we can change both their structure and the extent to which they imprison us.
