"For, in fact, I say the degree of vision that dwells in a man is a correct measure of the man. If called to define Shakespeare's faculty, I should say superiority of Intellect, and think I had included all under that. What indeed are faculties? We talk of faculties as if they were distinct, things separable; as if a man had intellect, imagination fancy, &c., as he has hands, feet, arms. That is a capital error. Then again, we hear of a man's "intellectual nature," and of his "moral nature," as if these again were divisible, and existed apart. Necessities of language do perhaps prescribe such forms of utterance; we must speak, I am aware, in that way, if we are to speak at all. But words ought not to harden into things for us. It seems to me, our apprehension of this matter is, for most part radically falsified thereby. We ought to know withal, and to keep forever in mind, that these divisions are at bottom but names; that man's spiritual nature, the vital Force which dwells in him, is essentially one and indivisible; that what we call imagination fancy, understanding, and so forth, are but different figures of the same Power of Insight, all indissolubly connected with each other, physiognomically related; that if we knew one of them, we might know all of them. ... You may see how a man would fight, by the way in which he sings; his courage, or want of courage, is visible in the word he utters, in the opinion he has formed, no less than in the stroke he strikes. He is one; and preaches the same Self abroad in all these ways."
"But there is more in Shakespeare's intellect than we have yet seen. It is what I call an unconscious intellect; there is more virtue in it than he himself is aware of. ... How much in Shakespeare lies hid; his sorrows, his silent struggles known to himself; much that was not known at all, not speakable at all: like roots, like sap and forces working underground! Speech is great but Silence is greater. "
