[284] Goethe, in the poem “Der Gott und die Bajadere,” has very beautifully described the ennoblement of gross love by means of ideal love.

[285] Henry Murger, in his “Vie de Bohème,” also alludes to the “incomprehensible” fact that “persons of standing who sometimes possess spirit, a name, and a coat cut according to the fashion, out of their love for the common will go so far as to raise to the level of an object of fashion a creature whom their very servant would not have chosen as a mistress.”
