“I have a feeling it is more or less the same part of my brain which does both [math and music]… they speak to the same place, the same aesthetic…”

Songs of the Soul (1971)
Context: Now what should be the relation between science and spirituality? It should be a relation of mutual acceptance and true understanding. It is an act of folly on our part to expect the same truth, the same knowledge and the same power from both science and spirituality. We must not do that. Neither must we set up the same goal for science and spirituality.

Some Reasons Why (1881)
Context: Suppose then, that I do read this Bible honestly, fairly, and when I get through I am compelled to say, “The book is not true.” If this is the honest result, then you are compelled to say, either that God has made no revelation to me, or that the revelation that it is not true, is the revelation made to me, and by which I am bound. If the book and my brain are both the work of the same Infinite God, whose fault is it that the book and the brain do not agree? Either God should have written a book to fit my brain, or should have made my brain to fit his book.

Peter Quince at the Clavier (1915)
Context: Just as my fingers on these keys Make music, so the self-same sounds On my spirit make a music, too. Music is feeling, then, not sound;
And thus it is that what I feel,
Here in this room, desiring you,
Thinking of your blue-shadowed silk,
Is music.

Quoted in Bryant American Pictures And Their Painters (1917), p. 302
