ABSTRACT
At a psychological level, (according to Jean Paul Sartre’s philosophical analysis), midlife does not exist as a “thing-in-itself”. “Acting out” does not exist as a “thing-in-itself”. It is a definition used by psychoanalysts to describe certain behaviours. The same would apply for midlife concept: it is something defined by the analyst in his field of work. It is not something that exists on its own; it is a very interesting concept, but it should not be formulated in the abstract.
