Goethe, Italian Journey
, tr. W.H. Auden and Elizabeth Mayer (1962; rpt. London: Penguin Books, 1970), p. 10 (from the translators' Introduction):
To Goethe, a man who looks at a beautiful cloud without knowing, or wishing to know, any meteorology, at a landscape without knowing any geology, at a plant without studying its structure and way of growth, at the human body without studying anatomy, is imprisoning himself in that aesthetic subjectivity which he deplored as the besetting sin of the writers of his time.
