To Charles Augustus Strong
Hotel Bristol
Rome. April 8, 1931
I am glad you have put your theory of perception into its final shape, and shall be interested in seeing—and hearing—the terms in which you now express it. As to Relativity, I may not be able to follow your arguments and am, in a sense, less personally interested, because I have come to a quietus of my own on the subject. When you are here, if you still want to work, I can give you a book of Maritain’s in which Einstein is treated intelligibly and intelligently, though of course from a far distant point of view. I am, in my old age, acquiring the faculty which Leibniz said he had of agreeing with Everybody. I agree with Maritain, but I agree with Einstein also: it is only a question of the place which one assigns to certain sorts of science or speculation. Maritain thinks what I call “specious” absolute: and it is, for the moralist or the poet: it is the spiritual reality. But the test of material Existence is practical: so that the tables are turned when you approach cosmology. The cosmology of Maritain is pure myth, as that of Einstein is sheer mathematics.
