Wordsworth's Preface to Lyrical Ballad

Do you agree with Wordsworth's poetic creed? 
First of all for give the answer of this question we have to clear about Wordsworth's poetic creed...
Wordsworth's poetic creed initiated the Romantic era by emphasizing feeling, instinct and pleasure above formality. Wordsworth gave expression to inchoate human emotions. In the Preface to Lyrical Ballad his main ideas of a new theory of poetry, subject matter of poetry and language of poetry. Wordsworth explained his poetic concept, "The majority of the following poems are to be considered as experiments they were written chiefly with view of ascertain how far the Language of conversation in the middle and lower classes of society is adopted to the purpose of poetic pleasure. The experiment with vernacular language was not enough of a departure from the norm, the focus on simple, uneducated country people as the subject of poetry. True to traditional ballad from the poems depict realistic characters in realistic situations.
Thus,  Wordsworth chiefly talk about the object and language in his poetic creed and I'm agree with him that...  The principle object,in these poems was to choose incidents and situation from common life and to relate and describe them, throughout as far as possible in selection of language really used by men, and certain colouring of  Imagination.defined by Wordsworth's as.. "Poetry is the spontaneous overflow of powerful feelings :it takes its origin from emotion recollected in tranquility.

What is Poet?
A poet is a man speaking to men, endowed with more lively sensibility. And further he says that,who has a greater knowledge of human nature and more comprehensive soul,  who rejoice more than other man in the spirit of life. Thus, we can say that poet deals with human's emotions in more creative way.

Do you think poems are better written with simple language ? Do common men Peasants from labourers poor people make better subject for poem than landlords , rich people? is poet genius  as Coleridge thinks or S/he common man speaking to common men as Wordsworth  thinks?  
Imagination of One's mind and her/his spontaneous overflow of views is the poetry, no matter what kind of words used, and what is subject matter. Words of someone's feelings can be simple as well as4 complicated too, it doesn't matter but how deeply one can create himself's feelings into words. By reading it if someone feel like it is his own feelings than may be poet is succeed in his work. Thus,  I don't think that poems are better written in simple language it can be loafty also.

In the advertisement to the 1798 edition of lyrical Ballad , Wordsworth and Coleridge start that the poems in the collection were intended as a deliberate experiment in style and subject matter. Therefore both the poet start writing poem In his own way in real language of common man,  rather than in the lofty. And they believed that the first principle of Poetry should be pleasure.

Humble and rustic life, common men peasants from labourers poor people was generally chosen, because in that condition of life elementary feelings Co exist in a state of greater simplicity and consequently. But it doesn't mean that these only subject matter make better poetry than landlords and rich people.
