E.T.A. Hoffmann

“Why should not a writer be permitted to make use of the levers of fear, terror and horror because some feeble soul here and there finds it more than it can bear? Shall there be no strong meat at table because there happen to be some guests there whose stomachs are weak, or who have spoiled their own digestions?”
― E.T.A. Hoffmann

“There are... otherwise quite decent people who are so dull of nature that they believe that they must attribute the swift flight of fancy to some illness of the psyche, and thus it happens that this or that writer is said to create not other than while imbibing intoxicating drink or that his fantasies are the result of overexcited nerves and resulting fever. But who can fail to know that, while a state of psychical excitement caused by the one or other stimulant may indeed generate some lucky and brilliant ideas, it can never produce a well-founded, substantial work of art that requires the utmost presence of mind.”
― E.T.A. Hoffmann, Die Serapions Brüder: Gesammelte Erzählungen Und Märchen In Vier Bänden
