What is the role of poet according to emerson with reference to essay, ''poet", discuss.what are the functions of a true poet addvocated by emerson?

The poet, according to Emerson, has to be just about
everything. 

He has to be a seer into the soul of man, he
must be an interpreter and a
prophet.

 I
know not how it is that we need an interpreter; but the great majority of men seem to be
minors, who have not yet come into possession of their own, or mutes, who cannot report
the conversation they have had with
nature. 

Mankind may see
things about them in their world, but so very few ever put into words a great expression
that impacts, that influences, that makes value of the every day mundane to all other
men. This is the power of a poet that interprets.

The poet
must be a foreteller, a
prophet:

The sign and credentials of the poet are, that he
announces that which no man foretold. He is the true and only doctor; he knows and
tells; he is the only teller of news, for he was present and privy to the appearance
which he describes.

The poet
must have the ability to color and accompany life. This is
the difference between watching television in black and white or on an HD LCD screen in
living color. This is the difference between a tinny cheap radio and a live
orchestra.

We
hear, through all the varied music, the ground-tone of conventional life. Our poets are
men of talents who
sing.

Poets must have
imagination, and they must have energy.
