We have not reproduced the above schedule because it is exhaustive, or because its brief characterizations are entirely just, or because we propose to discuss these or like schemes in detail. Our immediate purpose in citing these propositions is merely to illustrate the multiplicity and variety, and more than all the futility, of attempts to classify societies up to date. We thus have a background for the remainder of the argument.
Before we proceed, another series of general propositions may be useful in binding together the divisions of our discus- sion.
