Language, in the proper sense of the term, is peculiar to man; so that, without a miraculous assumption of human powers, none but human beings can make words the vehicle of thought. An imitation of some of the articulate sounds employed in speech may be exhibited by parrots, and sometimes by domesticated ravens, and we know that almost all brute animals have their peculiar natural voices, by which they indicate their feelings, whether pleasing or painful. But language is an attribute of reason, and differs essentially not only from all brute voices, but even from all the chattering, jabbering, and babbling of our own species, in which there is not an intelligible meaning, with division of thought, and distinction of words.
