The coat which is perceived--in this sense of the word 'coat'-- is what I call a perceptual object.

We have to investigate the general character of these perceptual objects.
It is a law of nature that in general the situation of a sense-object is not only the situation of that sense-object for one definite percipient event, but is the situation of a variety of sense-objects for a variety of percipient events.

For example, for any one percipient event, the situation of a sense-object of sight is apt also to be the situations of sense-objects of sight, of touch, of smell, and of sound.

Furthermore this concurrence in the situations of sense-objects has led to the body--_i.e._ the percipient event--so adapting itself that the perception of one sense-object in a certain situation leads to a subconscious sense-awareness of other sense-objects in the same situation.

This interplay is especially the case between touch and sight.
