One of the surest tests of the superiority or inferiority of a poet is the way in which a poet borrows. Immature poets imitate mature poets steal bad poets deface what they take and good poets make it into something better or at least something different. The good poet welds his theft into a whole of feeling which is unique utterly different than that from which it is torn the bad poet throws it into something which has no cohesion. A good poet will usually borrow from authors remote in time or alien in language or diverse in interest.

What are the roots that clutch, what branches grow
Out of this stony rubbish? Son of man,
You cannot say, or guess, for you know only
A heap of broken images, where the sun beats,
And the dead tree gives no shelter, the cricket no relief,
And the dry stone no sound of water. Only
There is shadow under this red rock,
(Come in under the shadow of this red rock),
And I will show you something different from either
Your shadow at morning striding behind you
Or your shadow at evening rising to meet you;
I will show you fear in a handful of dust.

Fishing, with the arid plain behind me
Shall I at least set my lands in order?

London Bridge is falling down falling down falling down

Poi s'ascose nel foco che gli affina
Quando fiam ceu chelidon — O swallow swallow
