ABSTRACT
From 1950, Wilfred Bion began publishing papers on the language and thinking of schizophrenics in which were the seeds of the ideas he developed later on, in another seven papers, which gave birth to a psychoanalytical theory of the function of thinking and its disturbances. In his work, he uses in a very free way the ideas of different philosophers, which he transformed through his experience as a psychoanalyst. For pedagogical reasons, but also to show the evolution and the changes that Bion introduced. His ideas are contained in four books: Learning from Experience, Elements of Psycho-analysis, Transformations, whose subtitle is Change from Learning to Growth, and Attention and Interpretation. These four books contain developments and changes at a conceptual level and an innovative contribution to the theory of psychoanalytical technique. They are a contribution to understanding both the earlier and later parts of his work.
