The poet writes under one restriction only, namely, the necessity of giving immediate pleasure to a human being possessed of that information which may be expected from him, not as a lawyer, physician, a mariner, an astronomer, or a natural philosopher, but as a Man. 

Exp. These lines have been extracted from Preface to Lyrical Ballads by William Wordsworth. Here Wordsworth says that the poet writes poems to gives immediate pleasure to the reader.

 

According to Wordsworth, poets write poems to give immediate pleasure to his readers. A poet must give pleasure to his readers by his poems. In order to enjoy the pleasure of poetry, a reader does not need the knowledge of a specialist. The reader is not expected to possess the kind of knowledge which a lawyer or a physician or a sailor or an astronomer or a natural philosopher possesses. A human being, possessing ordinary knowledge which any man is expected to have is capable to enjoying poetry because the poet does not write for specialists. In other words, a reader need not possess any specialist knowledge in order to derive pleasure from poetry. Thus, the poet writes under one restriction only, that is, the necessity of giving immediate pleasure to his readers without possessing specialised knowledge. Poetry should give immediate pleasure to the readers and it is, according to Wordsworth, not a digression of the poet's art. In fact it is an acknowledgement of the beauty of the universe and of the worth and dignity of man.
