Dr. Forel is on safe ground when he claims that a rational psycho-therapy will select a treatment most appropriate to any given case of illness; not of course that the same practitioner may have equal skill in all forms of treatment. But if his therapeutic eclecticism is good, not the same commendation is to be made of his eclecticism in pathology. It sounds very broadminded to select all that is best in the pathologies of Adler, Freud, Janet, Jung and others and to weave them all together, but in the result one is inclined to echo Portia's complaint of Falconbridge. What would be said of a pathologist who agreed that malaria was sometimes due to parasitic infection from the mosquito and sometimes to inhaling bad air? The pathologies of Freud and Janet are as distinctive as this: if Janet's views are sound Freud's psycho-pathology cannot be upheld; it is no use repeating 'there is a lot in it'—we are dealing with scientific data, not political opinions.
