While Bion's group theory continues to inspire contemporary group psychothe
rapists, his theory of human emotion is not as well known. Bion also introd
uced a system of alphabetical and mathematic symbols to offer a shorthand f
or his epistemology in order to make his ideas accessible, flexible, and pr
actical for the working clinician. This article presents aspects of Bion's
theory and metapsychological shorthand to conceptualize affectual dimension
s of group process, thinking operations, and countertransference. The const
ructs considered include Klein's paranoid-schizoid and depressive positions
; manic defenses; basic assumptions; "proto-mental" and "pre-monitory" emot
ions; instinctive drives L, H, and K (plus or minus); beta elements; and al
pha functioning. With these ideas, the author was able to work through aspe
cts of a group experience in which, as leader, he unknowingly found himself
at an opposite affective pole from the members.
