[Within the animal kingdom, relations are often established by the characteristic and conventional sounds made by different species. In man these slowly assumed the form of words, at first only a few, then increasingly more and more numerous as required to describe what had happened and was happening to the senses or was elaborated by the brain. Communication thus was strictly limited by the range of perception of those sounds: by increasing the volume this range could be enlarged, but by very little and never, in the best of hypotheses, beyond the brief visual horizon. Recourse to sound instruments that could produce louder sounds soon began to be used, from the simplest to the most sophisticated: the common guiding principle was that they be able to vibrate the air or to produce noise and sounds that were more intense than those made by human beings.]
