The central topic of the Congress was the influence of existential philosophy on psychotherapy. For the psychoanalyst unfamiliar with existentialism, Alexander's report will serve as an excellent introduction. Those familiar with the subject will find the vignettes of the leading personalities in the existential hierarchy most interesting. A brief but lucid critique of existential philosophy from the standpoint of psychoanalysis is provided, which demonstrates among other things how little the existential 'analysts' realize that Freud fifty years ago had defined most of their basic concepts in much clearer terms than they now use.
