When a rainbow spans the sky the eye may rest with simple rapture on the arch of colours, or the mind may interpret it as an interplay between raindrops and light. This perceptibly separates the aesthetic relish of the colours from the scientific understanding of the bow. Archbishop Temple distinguished the restfulness of art from the restlessness of science. This applies to the wider aesthetic which includes natural products, such as snow-scenes or daffodils or rainbows, with the pictures, statues, buildings, poems, and other products of man-made art. The rainbow clearly separates the understanding sought by science from the immediate contemplative aesthetic satisfaction with the colours.
