He was writing in the 1940s, although his works were only published in 1956 after his death. I agree, but think that his views are not the end of the story.
I would argue similarly that the workings of the mind and consciousness are so immeasurably more complicated even than the physical workings of the brain, that it is not wise to think they are governed by the same laws as govern the brain. When you consider the mind or consciousness, you must enter a world of relationships if you mean to keep in touch with ordinary experience; and in this world I doubt if objective truth has any meaning, unless one person is trying to communicate it to another. It may exist, but it has no meaning. Just as when two lovers fall out and go their separate ways, their relationship still exists in the sense that they do not revert to their position before they fell in love; but the relationship has no meaning now, because they are out of love. Truth, relative or absolute, only comes alive in the world of relationships; and that means it only comes alive in an attitude of mind, which may well be flawed. Hence the well known view that the only knowledge which does not depend on experience is the theory of numbers, and possibly of kindred subjects! This was the thesis of Bertrand Russell and Whitehead’s book, Principles of Mathematics.
All this is implicit in my book, Man’s Relationship with God; but much of it is not explicit. This is the very basis of my theory of consciousness; and on this basis I develop the theory by showing that conduct moulds consciousness, and consciousness moulds conduct, until there is formed an equilibrium system in the mind and spirit of each person, which carries that person through the everyday world of conventional habit and fashion. I attempt to show how membership of a team, or of a community which is a loosely knit team, affects the workings of the individual mind, and in particular the individual’s confidence, because nobody wants to outrage other members of the community in which he lives gratuitously. So his conduct is inhibited or moulded by his relationship with the rest of the team. To break out of this system you need either a carefully thought out decision, or the interpenetration of two minds or spirits which introduces a new dimension into the world of human relationships. In fact it opens up the world of human and divine love; but the sad truth of my experience is that it is in the Army that you most readily find two minds thinking as one. And from my reading, it is only in War that you find the brotherhood of man truly practised. Would that it were different; but it looks as if it were true. My adventure ended in failure, not success.
In my book I begin first of all with religious beliefs, because I know about them, and they are easiest to analyse; but because orthodox beliefs are dead though they ought to be alive, I quickly move on to the Law. And I try to open up the world of relationships within the drama of Court proceedings, because only a hack tries to conduct his cases in a detached stereotyped way, and this approach is more likely to appeal to the reader. And the study of relationships, whether in the Law or any other discipline, culminates in the idea of the interpenetration of two minds, which means the instinctive understanding between two people, who can read each others’ thoughts without difficulty. And if the reader thinks this is a romantic idea, which ought to be confined to lovers, he is wrong. The German General Staff have believed in this for a long time, and considered such a marriage of minds to be necessary for the proper and effective conduct of War; and they knew about War, if anyone did! And I think you found the same thing in our own Army, when we started winning. It is not something you find readily in the Law, as we are much too much individualists; and this shows itself when cooperation is forced on us by the circumstances of a particular case. This world of interpenetrating minds is unbelievably more complicated than the world of relationships, which itself is unbelievably more complicated than the mere workings of the brain. It is a world beyond that of everyday experience; and for all I know, there are worlds beyond worlds beyond this; for example in the experiences Jesus must have had before he took his disciples up the mountain for the Transfiguration. But my knowledge largely ends with the world of relationships.
