"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 from that 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." -TS Eliot
It's important to state that when I utilize this in any of my writing, it's supposed to be blatant. That is to say, if the reader doesn't notice the "Rip," they can't attribute it to plagiarism. If the reader DOES notice, it's going to be obvious, as is the intention.
Just as an offhand reference, including the words "full of sound and fury" will elicit no reaction from the uninitiated. For those who get the reference it should be fully understood that I'm not trying to "steal" words from the pen of The Bard. They'll know intuitively that I'm trying to incorporate his intentions into the mix. Whether from that particular line or from the entirety of the "Scottish Play."
