I will now take another and more complex case of construction, which will bring out some other facts about what I have termed "constructs." I hear in the street a piercing howl, which suggests a dog in pain. Rising from my seat and going to the window, I see a white terrier with a black patch over the left eye limping down the road on three legs. Now, what was the nature of the construct framed at the bidding of the piercing howl? A dog in pain. But what dog? The nature of the howl suggested a small dog; but there was nothing further to particularize him. The construct was, therefore, exceedingly vague and ill defined, and was not rendered definite and particular till I went to the window, and saw that it was a white terrier with a black patch over the eye. The howl, moreover, suggested certain activities of the dog. The construct was not merely a passive, inanimate object, like the orange, but an object capable of performing, and actually performing, certain actions. Here, again, we can only say that it is through experience that special activities are associated with certain objects. Just as the construct orange is capable of exciting sensations of taste, so the construct dog is capable of doing certain things and performing certain actions, that is, of affecting us in certain further ways. But, further, the howl suggested a dog in pain. No amount of sensations entering into any manner of relations could give me that element of the construct. I can neither see, touch, taste, smell, nor hear pain in another being. Pain is entirely subjective and known only to the sufferer. But I have been a sufferer. I have experienced pain and pleasure. And just as my experiences, individual and ancestral, lead me to project into inanimate objects certain qualities, the products of my sensations, so do my experiences, individual and ancestral, lead me to project into certain animals feelings analogous to those I have myself experienced. This is sometimes described as an inference. But if we call this an inference, then we must, I think, call the taste, smell, and feel of the orange I see before me inferences. In both cases the inference, if we so call it, enters at once into the immediate construct. And when I went to the window and saw the dog limping down the street, I saw also a small boy, with arm drawn back, in the act of throwing a stone. In other words, I saw the objects in the scene before me standing in certain relations to each other. I concluded that the boy had thrown a stone at the dog and was about to throw another. In other words, I saw the scene before me as part of a sequence of events.
