An example of an analogy for a scientific notion,
"…the fact that subhuman animals learn to reason with sometimes startling effectiveness, without learning to speak, does not prove that men can do so, any more than the fact that a rat can copulate without the mediation of imitative learning or practice proves that a chimpanzee can do so"
