The cornerstone of W. R. Bion's theory of individual and group development
is that thinking is a primary emotional need, and it matures in the context
of social communication. Bion (1970) formulated the essential relationship
between thinking and communicating in terms of the "container-contained" r
elationship Bion (1970) described three types of communication, occurring o
n different levels of development: commensal, symbiotic, and parasitic. The
se patterns involve normal and pathological variations of the container-con
tained and call for different expressions of the therapist's subjectivity.
In this paper I describe each of these alterations as they apply to group t
herapy and to therapeutic activity. I include case examples of how I utiliz
e the conceptual framework in my work.
