Multiplicity and constant transformation in the forms which the state assumes are as comprehensible upon the hypothesis proposed as is the numerical diversity of independent states. The consequences of conjoint behavior differ in kind and in range with changes in “material culture,” especially those involved in exchange of raw materials, finished products and above all in technology, in tools, weapons and utensils. These in turn are immediately affected by inventions in means of transit, transportation and intercommunication. A people that lives by tending flocks of sheep and cattle adapts itself to very different conditions than those of a people which ranges freely, mounted on horses. One form of nomadism is usually peaceful; the other warlike. Roughly speaking, tools and implements determine occupations, and occupations determine the consequences of associated activity. In determining consequences, they institute publics with different interests, which exact different types of political behavior to care for them. In spite of the fact that diversity of political forms rather than uniformity is the rule, belief in _the_ state as an archetypal entity persists in political philosophy and science. Much dialectical ingenuity has been expended in construction of an essence or intrinsic nature in virtue of which any particular association is entitled to have applied to it the concept of statehood. Equal ingenuity has been expended in explaining away all divergencies from this morphological type, and (the favored device) in ranking states in a hierarchical order of value as they approach the defining essence. The idea that there is a model pattern which makes a state a _good_ or true state has affected practice as well as theory. It, more than anything else, is responsible for the effort to form constitutions offhand and impose them ready-made on peoples. Unfortunately, when the falsity of this view was perceived, it was replaced by the idea that states “grow” or develop instead of being made. This “growth” did not mean simply that states alter. Growth signified an evolution through regular stages to a predetermined end because of some intrinsic nisus or principle. This theory discouraged recourse to the only method by which alterations of political forms might be directed: namely, the use of intelligence to judge consequences. Equally with the theory which it displaced, it presumed the existence of a single standard form which defines _the_ state as the essential and true article. After a false analogy with physical science, it was asserted that only the assumption of such a uniformity of process renders a “scientific” treatment of society possible. Incidentally, the theory flattered the conceit of those nations which, being politically “advanced,” assumed that they were so near the apex of evolution as to wear the crown of statehood.
