The principal aim Wordsworth proposed to himself in writing poems was to select situations and incidents from ordinary life as subject for them, and then to describe the facts with a language used by common men, maybe making them the more interesting.
The kind of life by which this events are chosen is rural life, because according to Wordsworth in that condition the passions of human heart can find a better soil where grow up; they become durable as they come from elementary feelings and they can incorporate themselves with the beautiful and everlasting forms of Nature.
   Secondly Wordsworth speaks about the kind of language that has to be used in Romantic poems: it should be familiar, basic, and it should be lacking in the typical expressions of social vanity. A language that comes from common situations and ordinary events is more appropriate to communicate with everybody's heart.
   The Romantic poet is a man speaking to men, so he has to posses sensibility, tenderness, enthusiasm, and above all a great knowledge of human nature. He has to listen at his passions and volitions, that can helps him in understanding and comprehending all the feelings he wants to speak about in his poems. Beyond this things the poet should have a disposition to be affected more than other men by absent things as if they were present and he should have acquired a greater readiness and power in expressing what he thinks and feels.
   Lastly Wordsworth describes poetry as a spontaneous overflow of powerful feelings, which means it has origin when the poet looks back to an experience he has lived and that has marked him so indelibly he felt in must to hand down that feelings to all the mankind.
