Let an illustration make this plainer. I open the first book I take up, and read the first sentence that meets my eye: 'Newton saw the handiwork of God in the heavens as plainly as Paley in the animal kingdom.' I immediately look back and try to analyze the subjective state in which I rapidly apprehended this sentence as I read it. In the first place there was an obvious feeling that the sentence was intelligible and rational and related to the world of realities. There was also a sense of agreement or harmony between 'Newton,' 'Paley,' and 'God.' There was no apparent image connected with the words 'heavens,' or 'handiwork,' or 'God'; they were words merely. With 'animal kingdom' I think there was the faintest consciousness (it may possibly have been an image of the steps) of the Museum of Zoology in the town of Cambridge where I write. With 'Paley' there was an equally faint consciousness of a small dark leather book; and with 'Newton' a pretty distinct vision of the right-hand lower corner of curling periwig. This is all the mind-stuff I can discover in my first consciousness of the meaning of this sentence, and I am afraid that even not all of this would have been present had I come upon the sentence in a genuine reading of the book, and not picked it out for an experiment. And yet my consciousness was truly cognitive. The sentence is 'about realities' which my psychological critic--for we must not forget him--acknowledges to be such, even as he acknowledges my distinct feeling that they ARE realities, and my acquiescence in the general rightness of what I read of them, to be true knowledge on my part. Now what justifies my critic in being as lenient as this? This singularly inadequate consciousness of mine, made up of symbols that neither resemble nor affect the realities they stand for,--how can he be sure it is cognizant of the very realities he has himself in mind?
