This article presents a new theory of reflexivity in systems of social meaning and action. It is argued that Russell's Theory of Logical Types, which formed the basis of the early work of the Palo Alto group, rests upon an inappropriate and largely outdated epistemology. The theory offered here rejects the assumption that reflexivity and paradox are coterminous. It is further argued that reflexivity is a natural and necessary feature of human systems of meaning. New analytic tools are offered for discerning problematic from nonproblematic reflexive loops. The new tools take the form of a symbol that can be used to represent the rules that organize reflexive relationships. The theory also contains a set of statements designed to delimit conditions under which problematic reflexive loops have ramifications for persons' mental health.
