From the essay 'Joseph Conrad' in Autumn Leaves by Andre Gide (as read in the Oyster App):
He admired Flaubert and Maupassant, whose praises he gladly sang ... (but) the very name of Dostoyevsky made him pale.
Gide's summation is worth quoting as well: 'No one had lived more brutally than Conrad; no one, afterwards, had submitted life to so patient, conscientious and learned a transmutation of art.'
