"I am by the law of my nature a reasoner. A person who should suppose I meant by that word, an arguer, would not only not understand me, but would understand the contrary of my meaning. I can take no interest whatever in hearing or saying any thing merely as a fact — merely as having happened. It must refer to something within me before I can regard it with any curiosity or care. My mind is always energic — I don't mean energetic; I require in every thing what, for lack of another word, I may call propriety, — that is, a reason why the thing is at all, and why it is there or then rather than elsewhere or at another time."

“Kean is original; but he copies from himself. His rapid descents from the hyper-tragic to the infra-colloquial, though sometimes productive of great effect, are often unreasonable.

“That passage is what I call the sublime dashed to pieces by cutting too close with the fiery four-in-hand round the corner of nonsense.”

“Intense study of the Bible will keep any writer from being vulgar, in point of style.”

“The principle of the Gothic architecture is infinity made imaginable. It is no doubt a sublimer effort of genius than the Greek style; but then it depends much more on execution for its effect.”

“I shall attack Chemistry, like a Shark.”
