Discuss Wordsworth’s theory of poetry as propounded by him in the Preface to Lyrical Ballads.

Much of Wordsworth's philosophy of poetry is outlined in
his Preface.  The idea that poetry should focus on commonplace subjects is something
that Wordsworth clung to in his body of poetry.  Wordsworth sought to bring out the
powerfully universal qualities in subjects that are very ordinary.  A woman in the
field, a set of daffodils, or the conversation between two people in love are ordinary
subjects, but ones that allowed Wordsworth to evoke some of the most powerful of
images.  In his language and context, the words and choice of words are ones that
reflect "language used by men."  Wordsworth wrote in a style that was approachable by
common people and in this, Wordsworth sought to democratize poetry and its
appreciation.  Finally, in "presenting the usual in an unusual way," Wordsworth was able
to bring out the universal from the specific, the objective from the subjective, and in
the process, allow his poetry to "see into the life of things" and create a new venue
where poetry allows the individual to open new doors of
perception.
