However much these two types may seem to exclude each other in their conception, and actually do so when translated into the jargon of party, in reality they are by no means mutually exclusive. Those forms of human society which we see both in the present and the past are by no means pure types, but show the most varied gradation and interpenetration of both types; according as the need for common defence or for individual interests comes to the fore, the military type, that rules and regulates everything, or the industrial, that aims at free union, will preponderate. The vast majority of all forms of society, including the modern Great Powers, are still of the military type, for obvious reasons. The "idea of the State" is powerful within them, but only some of the most advanced, which from their peculiar circumstances are less threatened by the danger of war, and therefore devote themselves more largely to industry and commerce, such as England and America, are now inclining more to the industrial type. Which of the two forms deserves the preference cannot, of course, be determined _a priori_. Spencer gives it evidently to the industrial type, as being a higher form of development, and he thinks that, in the more or less distant future, this will acquire the supremacy (_Principles_, iii., Sec. 577). But he recognises also, as was only to be expected, that it has only rarely been possible to dispense with the military and compulsory organisation, whether in the present or the past, and that even in the future it will still in many cases be necessary for social development according to local conditions; and that accordingly a universal acceptance of co-operative work by convention, on the Anarchist's plan, cannot be imagined as possible, because, in social organisms as well as in individual organisms, the development of higher forms by no means implies the extirpation of lower forms. If we miss already, at this point, one of the most essential traits of Anarchist doctrine, viz., its absolute character, Spencer's so-called Anarchism shrinks still more into nothingness, when we approach the industrial type as he describes it in its complete state.
