The poet thinks and feels in the spirit of human passions.

But Poets do not write for poets alone, but for men, unless therefore we are advocates for that admiration which subsists upon ignorance, and that pleasure which arises from hearing what we do not understand, the poet must descend from this supposed height, and, in order to excite rational sympathy, he must express himself as other men express themselves.

Or,

 

Among the qualities there enumerated as principally conducing to from a Poet, is implied nothing differing in kind from other men, but only in degree.

 

Exp. These lines belong to Preface to Lyrical Ballads by William Wordsworth. Here Wordsworth asserts that the poet's language is not materially different from that of other men.

 Wordsworth emphasizes the point that the poet does not differ from other human beings in kind, but that's poet differs from other people only in degree. Wordsworth meant to say that the poet is a speaking to men. The poet experiences the same feelings, the same sentiments, and the same passions which other human being experience. The poet thinks and feels in the spirit of human passion. Therefore, the poet's language cannot differ in any material degree from the language of all other men, But the poet experiences these feelings and passions more deeply. The poet's capacity for both thinking and feeling is much greater than that of other people. He also has a greater power to express his thoughts and feelings. The poet belongs to the same species as other human beings, but his faculties and capacities are far more productive and fertile than those of other human beings. The poet writes not for his own benefit only: he does not write only for himself or for his fellow-poets. He writes chiefly for the ordinary people. Hence the poet is to express himself as other men express themselves. It is, on this ground, among others, that Wordsworth tries to defend his view that poetry should be written in the real language of men.
