a question is of less importance than the principle accepted by either student as the groundwork of his theory, the mainstay of his opinion.  It is no part of my project or my hope to establish the actual date of any among the various plays, or to determine point by point the lineal order of their succession.  I have examined no table or catalogue of recent or of earlier date, from the time of Malone onwards, with a view to confute by my reasoning the conclusions of another, or by the assistance of his theories to corroborate my own.  It is impossible to fix or decide by inner or outer evidence the precise order of production, much less of composition, which critics of the present or the past may have set their wits to verify in vain; but it is quite possible to show that the work of Shakespeare is naturally divisible into classes which may serve us to distinguish and determine as by landmarks the several stages or periods of his mind and art.

Of these the three chief periods or stages are so unmistakably indicated by the mere text itself, and so easily recognisable by the veriest tiro in the school of Shakespeare, that even were I as certain of being the first to point them out as I am conscious of having long since discovered and verified them without assistance or suggestion from any but Shakespeare himself, I should be disposed to claim but little credit for a discovery which must in all likelihood have been forestalled by the common insight of some hundred or more students in time past.  The difficulty begins with the really debatable question of subdivisions.  There are certain plays which may be said to hang on the borderland between one period and the next, with one foot lingering and one advanced; and these must be classed according to the dominant note of their style, the greater or lesser proportion of qualities proper to the earlier or the later stage of thought and writing.  At one time I was inclined to think the whole catalogue more accurately divisible into four classes; but the line of demarcation between the third and fourth would have been so much fainter than those which mark off the first period from the second, and the second from the third, that it seemed on the whole a more correct and adequate arrangement to assume that the last period might be subdivided if necessary into a first and second stage.  This somewhat precise and pedantic scheme of study I have adopted from no love of rigid or formal system, but simply to make the method of my critical process as clear as the design.  That design is to examine by internal evidence alone the growth and the expression of spirit and of speech, the ebb and flow of thought and style, discernible in the successive periods of Shakespeare’s work; to study the phases of mind, the changes of tone, the passage or progress from an old manner to a new, the reversion or relapse from a later to an earlier habit, which may assuredly be traced in the modulations of his varying verse, but
