“The works of Lavoisier and his associates operated upon many of us at that time like the Sun's rising after a night of moonshine: but Chemistry is now betrothed to the Mathematics, and is in consequence grown somewhat shy of her former admirers.”— Johann Goethe (c.1816), “Correspondence with Luke Howard”, Continental Journey (Ѻ)
“The world admires wealth and velocity—these are the things for which everyone strives. Railroads, the post, steamboats, and all possible modes of communication are the means by which the world overeducates itself and freezes itself in mediocrity. We will be, with a few others, the last of an epoch that does not promise to return any time soon.”— Johann Goethe (1825), “Letter to Carl Zelter” (Ѻ)
“Mathematics has the completely false reputation of yielding infallible conclusions. Its infallibility is nothing but identity. Two times two is four, but it is just two times two, and that is what we call four for short. But four is nothing new at all. And thus it goes on and on in its conclusions, except that in the higher formulas the identities fades out of sight.”— Johann Goethe (c.1820); see: Goethe and mathematics (Ѻ)
“Every day we should hear at least one little song, read one good poem, see one exquisite picture, and, if possible, speak a few sensible words.”— Johann Goethe (c.1820), Wilhelm Meister's Lehrjahre (Apprenticeship) (1786-1830), Book V, Ch. 1 (Ѻ)
“Only a person who has himself experienced the impact of a fertile idea will understand what passionate activity is stirred in our minds, what enthusiasm we feel, when we glimpse in advance and in its totality something which is later to emerge in greater and greater detail in the manner suggested by its early development. Thus, the reader must surely agree, having been captured and driven by such an idea, I was bound to be occupied with it, if not exclusively, nevertheless during the rest of my life.”— Johann Goethe (1831), reflection of his 1786-87 visit to a public garden in Palermo, Sicily (Ѻ)
“Of all discoveries and opinions, none may have exerted a greater effect on the human spirit than the doctrine of Copernicus. The world had scarcely become known as round and complete in itself when it was asked to waive the tremendous privilege of being the center of the universe. Never, perhaps, was a greater demand made on mankind for by this admission so many things vanished in mist and smoke! What became of our Eden, our world of innocence, piety and poetry; the testimony of the senses; the conviction of a poetic religious faith? No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown, indeed not even dreamed of.”— Johann Goethe (c.1820) (Ѻ)

Praise | Tribute
The following are quotes on or about Goethe:
“Goethe was raised to the rank of Shakespeare.”— Henry Adams (1907), The Education of Henry Adams
“Words like 'great' and 'genius' could aptly be used for but a select number of artists—for Michelangelo or say Shakespeare. In the United States, the works of these great artists have been incorporated into popular culture as the epitome of visual and linguistic beauty. By contrast, on these shores, Goethe's works remain largely unread and rarely discussed except among college students, most of whom develop a healthy dose of amnesia shortly after graduation.”— Daniel Spiro (2005), “Remember to Live! The Philosophy of Johann Wolfgang von Goethe”
