He observed closely and pondered deeply over what he observed.

At the age of eight he began to converse more freely, and it was in that year that he startled his mother with the question, "Mamma, are you not sometimes overpowered by the sense of your own identity ?" Lady Chillingly,--I was about to say rushed, but Lady Chillingly never rushed,--Lady Chillingly glided less sedately than her wont to Sir Peter, and repeating her son's question, said, "The boy is growing troublesome, too wise for any woman: he must go to school." Sir Peter was of the same opinion.

But where on earth did the child get hold of so long a word as "identity," and how did so extraordinary and puzzling a metaphysical question come into his head?
Sir Peter summoned Kenelm, and ascertained that the boy, having free access to the library, had fastened upon Locke on the Human Understanding, and was prepared to dispute with that philosopher upon the doctrine of innate ideas.

Quoth Kenelm, gravely, "A want is an idea; and if, as soon as I was born, I felt the want of food and knew at once where to turn for it, without being taught, surely I came into the world with an 'innate idea.'" Sir Peter, though he dabbled in metaphysics, was posed, and scratched his head without getting out a proper answer as to the distinction between ideas and instincts.
