Mock on, mock on,Voltaire Rousseau; Mock on, mock on,'tis all in vain! You throw the sand against the wind, And the wind blows it back again.

Where do you get your taste in authorsöThat damned library of yours! (He indicates the small bookcase at rear.) Voltaire, Rousseau, Schopenhauer, Nietzsche, Ibsen! Atheists, fools, and madmen! And your poets! This Dowson, and this Baudelaire, and Swinburne and O'Neill Oscar Wilde, and Whitman and Poe! Whoremongers and degenerates! Pah! When I've three good sets of Shakespeare there (he nods at the large bookcase) you could read.
