more generic recepts afterwards experienced involves any demand upon the conceptual faculty, or implies that the child could only extend this name from a house-dog to a terrier by first performing an act of introspective thought—which, indeed, as we shall see later on, it is demonstrably impossible that a child of this age can be able to do. Nevertheless, it is evident that already the child has done more than the parrot. For a parrot will never extend its denotative name of a particular dog to the picture, or even to the image of a dog. The utmost that a parrot will do is to extend the denotative name from one particular dog to another particular dog, which, however, may differ considerably from the former as to size, colour, and general appearance. Still, I presume, no one will maintain that thus far there is the faintest evidence of a difference of kind between the connotative faculty of the bird and that of the child. All that these facts can be held to show is that—in the words already quoted from M. Taine while narrating these facts—“analogies which do not strike animals strike men.” Or, in my own phraseology, the receptual faculties of a parrot do not go further than the receptual faculties of a very young child: consequently, the denotative name in the case of the parrot only undergoes the first step in the process of receptual extension—namely, from a house-dog to a terrier, a setter, a mastiff, a Newfoundland, &c. But in the case of the child, _after having reached this stage_, the process of extension continues, so as to embrace images, and eventually pictures of dogs. This difference, however, only shows an advance in the merely receptual faculties: does not suggest that in order to carry the extension of the name through these second and third stages, demand has yet been made on the distinctively human powers of conceptual thought—any more than such powers were required to carry it through the first stage in the case of the parrot.
