Page:A study of Shakespeare (IA cu31924013158393).pdf/28

 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 can only be traced by ear and not by finger. I have busied myself with no baseless speculations as to the possible or probable date of the first appearance of this play or of that on the stage; and it is not unlikely that the order of succession here adopted or suggested may not always coincide with the chronological order of production; nor will the principle or theory by which I have undertaken to class the successive plays of each period be affected or impaired though it should chance that a play ranked by me as belonging to a later stage of work should actually have been produced earlier than others which in my lists are assigned to a subsequent date. It is not, so to speak, the literal but the spiritual order which I have studied to observe and to indicate: the periods which I seek to define belong not to chronology but to art.
