"Lamarck, according to Cuvier, was a fantasist. Like the 'enchanted palaces of our old romances,' his theories were built on 'imaginary foundations,' so that while they might 'amuse the imagination of a poet,' they could not 'for a moment bear the examination of anyone who has dissected a hand, a viscus, or even a feather.'"
