Psychoanalysis began with Freud; it is his brain-child. But thankfully it has not remained static. Its ideas have developed and its focus has changed; or rather new foci were brought into the ambit of its ideas. This was due in part to the change in the cultural environment within which psychoanalysis was practised and its ideas developed, and also partly because the patients who came to analysis and the problems they brought to it changed. Still throughout this development it maintained a continuity in its loyalty to some of Freud's most basic ideas.
