LOOK round the room in which you are seated and draw up a list of the things you can see in their natural state-just as they are found before they have been tampered with by man. There is coal on the fire, water in the glass, and possibly Howers in the vase. There seems to be little else. Among all this collection of things-chairs, cutlery, books, wall-paper, clothing, curtains, electric switches, carpet, pictures, nails-what is there true to nature? Even the water might be soda water, the fire an electric one, and the flowers imitation.
