Oh, where have you gone, you blissful dreams of future happiness - 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.

The magic of music is so strong, getting stronger, it should break any shackle of another art.

It may even be that, as you look more closely, to recognize the hidden seed which, born of a secret union, grows into a luxuriant plant and spreads forth into a thousand tendrils, until a single blossom, swelling to maturity, absorbs all the life-sap and kills the seed itself. [...] I came to feel that what we call simply dream and imagination might represent the secret thread that runs through our lives and links its varied facets; and that the man who thinks that, because he has perceived this, he has acquired the power to break the thread and challenge that mysterious force which rules us, is to be given up as lost.
