As the group whose good esteem is to be secured in this way grows larger, more patent means are required to indicate the imputation of merit for the leisure performed, and to this end uniforms, badges, and liveries come into vogue.

The wearing of uniforms or liveries implies a considerable degree of dependence, and may even be said to be a mark of servitude, real or ostensible.

The wearers of uniforms and liveries may be roughly divided into two classes-the free and the servile, or the noble and the ignoble.

The services performed by them are likewise divisible into noble and ignoble.

Of course the distinction is not observed with strict consistency in practice; the less debasing of the base services and the less honorific of the noble functions are not infrequently merged in the same person.
