It should be remarked that all these forms, or at least the first two, admit of degree, and even of very wide differences; for democracy may include the whole people, or may be restricted to half. Aristocracy, in its turn, may be restricted indefinitely from half the people down to the smallest possible number. Even royalty is susceptible of a measure of distribution. Sparta always had two kings, as its constitution provided; and the Roman Empire saw as many as eight emperors at once, without it being possible to say that the Empire was split up. Thus there is a point at which each form of government passes into the next, and it becomes clear that, under three comprehensive denominations, government is really susceptible of as many diverse forms as the State has citizens.

There are even more: for, as the government may also, in certain aspects, be subdivided into other parts, one administered in one fashion and one in another, the combination of the three forms may result in a multitude of mixed forms, each of which admits of multiplication by all the simple forms.
