However, in his report on psychoanalysis in 1913, Janet argued that many of the novel terms of psychoanalysis were only old concepts renamed, even down to the way in which his own "psychological analysis" preceded Freud's "psychoanalysis". This provoked angry attacks from Freud's followers, and thereafter Freud's own attitude towards Janet cooled. In his lectures of 1915-16, Freud said that "for a long time I was prepared to give Janet very great credit for throwing light on neurotic symptoms, because he regarded them as expressions of "idées inconscientes" which dominated the patients". However, after what Freud saw as his backpedalling in 1913, he said, "I think he has unnecessarily forfeited much credit".
