George Santayana, in a May 1933 letter to Iris Cutting Origo (no idea why this tab was open):
Not that we can, or ever do at heart, renounce our affections. Never that. We cannot exercise our full nature all at once in every direction; but the parts that are relatively in abeyance, their centre lying perhaps in the past or the future, belong to us inalienably. We should not be ourselves if we cancelled them. I don’t know how literally you may believe in another world, or whether the idea means very much to you. As you know, I am not myself a believer in the ordinary sense, yet my feeling on this subject is like that of believers, and not at all like that of my fellow-materialists. The reason is that I disagree utterly with that modern philosophy which regards experience as fundamental. Experience is a mere whiff or rumble, produced by enormously complex and ill-deciphered causes of experience; and in the other direction, experience is a mere peephole through which glimpses come down to us of eternal things. These are the only things that, in so far as we are spiritual beings, we can find or can love at all. All our affections, when clear and pure and not claims to possession, transport us to another world; and the loss of contact, here or there, with those eternal beings is merely like closing a book which we keep at hand for another occasion. We know that book by heart. Its verses give life to life.
I don’t mean that these abstract considerations ought to console us. Why wish to be consoled? On the contrary, I wish to mourn perpetually the absence of what I love or might love. Isn’t that what religious people call the love of God?
