The imagination belongs as much to philosophers as to poets. "We make ourselves pictures of the facts," said Wittgenstein; it is an act upon which "so much depends," Williams might add. "The imagination is the power of the mind over the possibilities of things," Stevens proposed, speaking, I suppose, as a poet. Would he grant, I wonder, that it operates, as it were, between the mind and the heart, and would therefore appear, to the philosopher, as the knowledge we carry in our hearts of the needs of others?
