The development of psycho-analysis can be considered as a reaction against an exaggeration of the synthetic point of view in suggestive psychotherapy and moral education. If the result should be that the synthetic point of view is considered unscientific in theory and arbitrary and bad technique in practice, this would mean another exaggeration. Even in psycho-analytic circles the problem of synthesis has arisen in relation with child-analysis and with influencing the super-ego.
