REPUBLIC, n. A nation in which, the thing governing and the thing governed being the same, there is only a permitted authority to enforce an optional obedience.
BRAIN, n. An apparatus with which we think that we think. That which distinguishes the man who is content to be something from the man who wishes to do something. A man of great wealth, or one who has been pitchforked into high station, has commonly such a headful of brain that his neighbors cannot keep their hats on. In our civilization, and under our republican form of government, brain is so highly honored that it is rewarded by exemption from the cares of office.
CENTAUR, n. One of a race of persons who lived before the division of labor had been carried to such a pitch of differentiation, and who followed the primitive economic maxim, "Every man his own horse."
NOUMENON, n. That which exists, as distinguished from that which merely seems to exist, the latter being a phenomenon. The noumenon is a bit difficult to locate; it can be apprehended only by a process of reasoning - which is a phenomenon.
