Since art is the expression of beauty and beauty can be understood only in the form of the material elements of the true idea it contains, art has become almost uniquely feminine. Beauty is woman, and also art is woman.
(Rémy De Gourmont (1858-1915), French critic, novelist. repr. In Selected Writings, ed. and trans. by Glen S. Burne (1966). "The Dissociation of Ideas," (1899).)
The grand style arises when beauty wins a victory over the monstrous.
(Friedrich Nietzsche (1844-1900), German philosopher, classical scholar, critic of culture. Friedrich Nietzsche, Sämtliche Werke: Kritische Studienausgabe, vol. 2, p. 596, eds. Giorgio Colli and Mazzino Montinari, Berlin, de Gruyter (1980). The Wanderer and His Shadow, aphorism 96 (1880).)
Beauty is that which is simultaneously attractive and sublime.
(Friedrich Von Schlegel (1772-1829), German philosopher. Aphorism 108 in Selected Aphorisms from the Athenaeum (1798), translated by Ernst Behler and Roman Struc, Dialogue on Poetry and Literary Aphorisms, Pennsylvania University Press (1968).)
Beauty, whether moral or natural, is felt, more properly than perceived.
(David Hume (1711-1776), Scottish philosopher. Enquiries Concerning the Human Understanding and Concerning the Principles of Morals, sect. 12 ("Of the Academical or Sceptical Philosophy"), part 3, p. 165, ed. L. Selby-Bigge, M.A., 2nd edition, London, Oxford University Press (1902).
