"Frequently, in flashes of momentary perception (the conditions more than the object being significant), we feel that certain isolated scenes and arrangements—a feathery landscape, a woman’s dress along the curve of a road by afternoon, or the solidity of a century-defying tree against the pale morning sky—hold something precious, some golden virtue that we must grasp. And yet when such a scene or arrangement is viewed later, or from another point, we find that it has lost its value and meaning for us. Perhaps this is because the thing we see does not hold that elusive quality, but only suggests to the mind some very different thing which remains unremembered."
