At the close of a paper read in Oxford by a very successful psycho-therapeutist, experienced largely in shell-shock cases, a critic exclaimed : “So what we must all do is to go to Harley Street and buy a new soul!” The doctor laughed, but half agreed. Afterwards, a Church of England dignitary said to me : “We shall all have to set up confessionals, else everyone will be going to these doctors !” The doctor had, in fact, alluded with envy to the Catholic Confessional, as responsible for happiness else unattainable, and as saving thousands from fear of, or indeed actual, madness. Psycho-analysis is indeed the fashion; almost a fad. Freudian plays are written ; Punch makes limericks on Jung. Hence it will be useful to disengage a few principles. I deliberately eliminate all I can, without, I hope, sacrificing anything essential. Especially I cannot print, without adaptation, the anecdotes I should wish to ; save in a technical paper, I could not well relate what would be most illustrative, at all.
