There are objects made up of two sense elements, one visual, the other auditory—the colour of a sunrise and the distant call of a bird. Other objects are made up of many elements—the sun, the water against the swimmer's chest, the vague quivering pink which one sees when the eyes are closed, the feeling of being swept away by a river or by sleep. These second degree objects can be combined with others; using certain abbreviations, the process is practically an infinite one. There are famous poems made up of one enormous word, a word which in truth forms a poetic object, the creation of the writer. The fact that no one believes that nouns refer to an actual reality means, paradoxically enough, that there is no limit to the numbers of them.
