Answer
This objection, oft-repeated since Lucretius, is sufficiently refuted by the gift of sensation in animals, and by the gift of intelligence in man. How should combinations "which chance has produced," produce this sensation and this intelligence (as has just been said in the preceding paragraph)? Without any doubt the limbs of animals are made for their needs with incomprehensible art, and you are not so bold as to deny it. You say no more about it. You feel that you have nothing to answer to this great argument which nature brings against you. The disposition of a fly's wing, a snail's organs suffices to bring you to the ground.
Modern natural philosophers have but expanded these so-called arguments, often they have pushed them to trifling and indecency. They have found God in the folds of the skin of the rhinoceros: one could, with equal reason, deny His existence because of the tortoise's shell.
Answer
What reasoning! The tortoise and the rhinoceros, and all the different species, are proof equally in their infinite variety of the same cause, the same design, the same aim, which are preservation, generation and death.
There is unity in this infinite variety; the shell and the skin bear witness equally. What! deny God because shell does not resemble leather! And journalists have been prodigal of eulogies about these ineptitudes, eulogies they have not given to Newton and Locke, both worshippers of the Deity who spoke with full knowledge.
Maupertuis' Objection
Of what use are beauty and proportion in the construction of the snake? They may have uses, some say, of which we are ignorant. At least let us be silent then; let us not admire an animal which we know only by the harm it does.
