The genius of poetry must work out its own salvation in a man; it cannot be matured by law and precept, but by sensation and watchfulness in itself. That which is creative must create itself - In Endymion, I leaped headlong into the sea, and thereby have become better acquainted with the soundings, the quicksands, and the rocks, than if I had stayed upon the green shore, and piped a silly pipe, and took tea and comfortable sdvice.
John KeatsHow sad it is when a luxurious imagination is obliged in self defense to deaden its delicacy in vulgarity, and riot in things attainable that it may not have leisure to go mad after things that are not.
John KeatsPoetry should be great and unobtrusive, a thing which enters into one's soul, and does not startle it or amaze it with itself, but with its subject.
