Cogitations

'Cogitations', the last of the posthumous publications, is a collection of occasional writings representing Bion's attempts to clarify and evaluate both his own ideas and those of others by casting them in written form and frequently addressing them to an imaginary audience.

Covering a period between February 1958 and April 1979, it delves into a wide range of material - psychoanalysis and science, mathematics and logic, literature and semantics.
