Bion, W. R. (ed. F. Bion) 1994. Karnac.
Cogitations is a collection of writings representing Bion’s attempts to clarify and evaluate both his own ideas and those of others. Covering a period between 1958 and 1979, this book touches on a range of areas: psychoanalysis and science, mathematics and logic, literature and semantics. Some of the writings contextualise Bion’s theoretical development, showing the doubts and arguments involved in the formation of his ideas; some focus on the more abstract points in his thinking; and others explore topics intended for books that were never written.
