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 KeatsThis living hand, now warm and capable Of earnest grasping, would, if it were cold And in the icy silence of the tomb, So haunt thy days and chill thy dreaming nights That thou would wish thine own heart dry of blood, So in my veins red life might stream again, And thou be conscience-calm'd. See, here it is-- I hold it towards you.
John Keats
