But how to evolve Shakespeare from his works, how to compel this Proteus into his proper and native form, is still the question. It is a problem of the highest difficulty. Something, indeed, of the poet's personal character and views we cannot help gathering as we read his dramas. Passages again and again occur of which, from their peculiar effect upon ourselves, from their conceivable reference to what we know of the poet's circumstances, or from their evident superfluousness and warmth, we do not hesitate to aver "There speaks the poet's own heart." But to show generally how much of the man has passed into the poet, and how it is that his personal bent and peculiarities are to be surely detected inhering in writings whose essential character it is to be arbitrary and universal, is a task from which a critic might well shrink, were he left merely to the ordinary resources of critical ingenuity without any positive and ascertained clue. In this case, however, all the world ought to know, there is a positive and ascertained clue. Shakespeare has left to us not merely a collection of dramas, the exercises of his creative phantasy in a world of ideal matter, but also certain poems which are assuredly and expressly autobiographic. Criticism seems now pretty conclusively to have determined, what it ought to have determined long ago, that the _Sonnets_ of Shakespeare are, and can possibly be, nothing else than a poetical record of his own feelings and experience--a connected series of entries, as it were, in his own diary--during a certain period of his London life. This, we say, is conclusively determined and agreed upon; and whoever does not, to some extent, hold this view knows nothing about the subject. Ulrici, who is a genuine investigator, as well as a profound critic, is, of course, right on this point. So, also, in the main, is M. Guizot, although he mars the worth of the conclusion by adducing the foolish theory of _Euphuism_--that is, of the adoption of an affected style of expression in vogue in Shakespeare's age--in order to explain away that which is precisely the most important thing about the Sonnets, and the very thing _not_ to be explained away: namely, the depth and strangeness of their pervading sentiment, and the curious hyperbolism of their style. In truth, it is the very closeness of the contact into which the right view of the Sonnets brings us with Shakespeare, the very value of the information respecting him to which it opens the way, that operates against it. Where we have so eager a desire to know, there we fear to believe, lest what we have once cherished on so great a subject we should be obliged again to give up, or lest, if our imaginations should dare to figure aught too exact and familiar regarding the traits and motions of so royal a spirit, the question should be put to us, what _we_ can know of the halls of a palace, or the mantled tread of a king? Still the fact is as it is.
