[The critic] serves up his erudition in strong doses; he pours out all the knowledge he got up the day before in some library or other, and treats in heathenish fashion people at whose feet he ought to sit, and the most ignorant of whom could give points to much wiser men than he. Authors bear this sort of thing with a magnanimity and a patience that are really incomprehensible. For, after all, who are those critics, who with their trenchant tone, their dicta, might be supposed sons of the gods? They are simply fellows who were at college with us, and who have turned their studies to less account, since they have not produced anything, and can do no more than soil and spoil the works of others, like true stymphalid vampires.
