it struck me what quality went to form a Man of Achievement, especially in Literature, and which Shakespeare possessed so enormously - I mean Negative Capability, that is, when a man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason.
John KeatsOr thou might'st better listen to the wind, Whose language is to thee a barren noise, Though it blows legend-laden through the trees.
John KeatsThe 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.
