The method of studying poetry which I have followed in this book was
sketched some years ago in my chapter on "Poetry" in Counsel Upon the
Reading of Books. My confidence that the genetic meth¬od is the natural
way of approaching the subject has been shared by many lovers of poetry.
I hope, however, that I have not allowed my insistence upon the
threefold process of "impression, transforming imagination, and
expression" to harden into a set formula. Formulas have a certain
dangerous usefulness for critics and teachers, but they are a very small
part of one's training in the appreciation of poetry. I have allotted
little or no space to the specific discussion of epic and drama, as
these types are adequately treated in many books. Our own generation is
peculiarly attracted by various forms of the lyric, and in Part Two I
have devoted especial attention to that field.
