" I appear to be embarked on the turbid waters of poetry and scholarship. And a career in poetry and knowledge is as hard to guide as Plato's horses. On the one hand I must range about discovering the fundamentals of knowledge, dipping into science, politics and other arcana, forever seeking an education that is both profound and practical; on the other, I must keep spiritually alive and brilliantly alive, for poetry is, as the moral Milton conceded in practice and precept, a sensuous, passionate, brutal thing. I put in the last adjective because I am modern and angry and puritanical. ...The relevance of such schedule to poetry is obvious. I cannot think it a pedantry that a man desiring to speak (or sing) something important should also desire to speak with certainty. Also if he lack scope, such as an acquaintance with science and an acquaintance with other languages, he will be romantic and an anachronism. "
