From a 1977 Philosophy and Literature interview with Jorge Luis Borges:

No, what I mean to say is that I have no personal system of philosophy. I never attempt to do that. I am merely a man of letters. In the same way, for example that — well, of course, I shouldn’t perhaps choose this as an example — in the same way that Dante used theology for the purpose of poetry, or Milton used theology for the purposes of his poetry, why shouldn’t I use philosophy, especially idealistic philosophy — philosophy to which I was attracted — for the purposes of writing a tale, of writing a story? I suppose that is allowable, no?
