To Charles Augustus Strong
Hotel Bristol
Rome. December 23, 1936
I have now finished your book, except the French article which I remember pretty well and won’t re-read for the present. The total impression left on me is that you are to be congratulated on having turned out a compact volume, so well expressed, and that evidently satisfies you by the finality of its doctrine, and the conviction that the world, sooner or later, will have to accept it.
The book, however, is not easy reading, or very appealing to the imagination. You ought not to be disappointed if it is not widely read at first. You may exercise your influence perhaps indirectly through a few students who will adopt or adapt your doctrines and diffuse them in more popular forms.
You know that I am not inclined to discuss these matters any more. It would be useless, for both of us, and merely irritating. I agree with you in the view that there is a biological level beneath the psychological, and that all the dirty work is done below stairs, as it should be in any well-ordered household. But I see only confusion in using psychological terms for biological processes: except indeed when we do so, like Freud, with avowed figurative and mythological licence, because the biological detail is little understood, and it is only the large moral effects that interest us. My own thoughts, at present, are turned so decidedly in another direction that detailed psychological theory cannot hold my attention.
