Example text

This is how he narrates this experience: In those groups I discussed with the nurses the various cases that we had, in order to give them a general view of psychiatry. The nurses’ learning was astonishing. They had a vast accumulated experience, since most of them had worked for years in the Asylum. Their difficulty was that they could not conceptualize; therefore, that experience was of no use to them. When they began to understand the dynamics of mental illness and its origins in depression, they acquired a much greater lucidity and, consequently, their treatment of the patients improved.

Its characteristics are similar to those attributed by Freud to the Ego. This facet of mental activity in a group I have called the Work Group. The term embraces only mental activity of a particular kind, not the people who indulge it. R. Bion 1952, p. 442) Bion (1948–51, 1952) suggested that there were two levels of mental activity in the group: the ‘basic assumption group’ and the ‘work group’. This was clearly an application of Freud’s (1900) concepts of the ‘primary process’ and the ‘secondary process’.

This is clearly related to William James’ (1907) pragmatism, even though Pichon-Rivière never mentions this precedent. But pragmatism is, of course, implicit in some of his most cherished sources, such as Kurt Lewin (1948, 1951) and George Herbert Mead (1934), as their underlying philosophy. Therefore, for Pichon-Rivière, theories are not valid in themselves, but should always be evaluated in their relation with concrete human beings and their constant interchange with their environment. They are instruments for action and research, and their validity is derived from their effectiveness.
