"The ignorant creature knows nothing of the wise doctrines of Malthus, but spawns forth as many children of all sorts as ever she can, without the least prudential restraint. She has consequently far more than she can properly feed and rear; so that a large part perishes in infancy (and we are told that none of these except the human sucklings will rise to another life; poor bereaved monkey and donkey mothers, for instance, being altogether without the precious consolations of immortality); a considerable part is eaten up by mankind and other hungry animals, and the remainder can seldom get food enough."
