'the misfortune of poetry'

[Captain Benwick] was evidently a young man of considerable taste in reading, though principally in poetry . . . though shy, he did not seem reserved; it had rather the appearance of feelings glad to burst their usual restraints; and having talked of poetry, the richness of the present age, and gone through a brief comparison of opinion as to the first-rate poets . . . he shewed himself so intimately acquainted with all the tenderest songs of one poet, and all the impassioned descriptions of hopeless agony of the other; he repeated, with such tremulous feeling, the various lines which imaged a broken heart, or a mind destroyed by wretchedness, and looked so entirely as if he meant to be understood, that she ventured to hope he did not always read only poetry; and to say, that she thought it was the misfortune of poetry, to be seldom safely enjoyed by those who enjoyed it completely; and that the strong feelings which alone could estimate it truly, were the very feelings which ought to taste it but sparingly.

—Jane Austen, Persuasion (1817)
