For thoughts on things unseen, which stagnate and obstruct

The system, therefore; mind, sound in a body sane,

Keeps thoughts apart from facts, and to one flowing vein

Confines its sense of that which is not, but might be,

And leaves the rest alone. What ghosts do poets see?

What demons fear? what man or thing misapprehend?

Unchecked, the channel 's flush, the fancy 's free to spend

Its special self aright in manner, time and place.

Never believe that who create the busy race

O' the brain, bring poetry to birth, such act performed,
