“I have already said that a thing which 'exists in a person's head' and nowhere else is alternatively called an imaginary thing. The actual making of the tune is therefore alternatively called the making of an imaginary tune. This is a case of creation, just as much as the making of a plan or a disturbance, and for the same reasons, which it would be tedious to repeat. Hence the making of a tune is an instance of imaginative creation. The same applies to the making of a poem, or a picture, or any other work of art.”

Context: Life is what we make it, and the world is what we make it. The eyes of the cheerful and of the melancholy man are fixed upon the same creation; but very different are the aspects which it bears to them. To the one, it is all beauty and gladness; the waves of ocean roll in light, and the mountains are covered with day. Life, to him, flashes, rejoicing, upon every flower and every tree that trembles in the breeze. There is more to him, everywhere, than the eye sees; a presence of profound joy, on hill and valley, and bright, dancing water. The other idly or mournfully gazes at the same scene, and everything wears a dull, dim, and sickly aspect. The murmuring of the brooks is a discord to him, the great roar of the sea has an angry and threatening emphasis, the solemn music of the pines sings the requiem of his departed happiness, the cheerful light shines garishly upon his eyes and offends him. The great train of the seasons passes before him like a funeral procession; and he sighs, and turns impatiently away. The eye makes that which it looks upon; the ear makes its own melodies and discords: the world without reflects the world within.
