33. This all accommodated to the end of speech.
This is adjusted to the true end of speech, which is to be the
easiest and shortest way of communicating our notions. For thus he that would discourse of things, as they agreed
in the complex idea of extension and solidity, needed but use the word body to denote all such. He that to these
would join others, signified by the words life, sense, and spontaneous motion, needed but use the word animal to
signify all which partaked of those ideas, and he that had made a complex idea of a body, with life, sense, and
motion, with the faculty of reasoning, and a certain shape joined to it, needed but use the short monosyllable man,
to express all particulars that correspond to that complex idea. This is the proper business of genus and species:
and this men do without any consideration of real essences, or substantial forms; which come not within the reach
of our knowledge when we think of those things, nor within the signification of our words when we discourse
with others.
