 Tillyard agrees with Lewis that we shouldn’t mix biography and criticism by allowing our knowledge of the author's life to take shortcuts and make hasty conclusions because we think we know the author.But Lewis is too concerned about things (37), writes Tillyard, and too little concerned with people.Another thing that Tillyard begins to do in this chapter is to suggest that the poet is a cut above the average person, for example, by writing about “the superior penetration of poetic genius” (38); later he will call Wordsworth “a superior person” (68) and Milton one “who is truly virtuous.” He will say that Milton “has inhabited heavens and hells unbearable by the ordinary man” (74) and that Shakespeare “reached a sanity richer than the normal” (75).
