To place social physics on a scientific basis is a task of great difficulty, since social theories are still perverted by theological and metaphysical doctrines. All I can hope to do is to point out general principles which may serve to correct the intellectual anarchy which is the cause of the moral and political anarchy of the present day. I propose to state first how the institution of a science of social physics bears upon the principal needs and grievances of society, so that men worthy of the name of statesmen may realise that such labours are of real utility. So far, positive philosophy has worked timidly and tentatively, and has not been bold and broad and general enough to cope with intellectual anarchy in social questions; but it is necessary now that it play a more dominant part in life, and lead society out of the turmoil in which it has tossed for three centuries.
At present, society is distracted by two conflicting influences, which may be called the theological polity and the metaphysical polity.
The theological polity at one time exercised a beneficent influence on society; but for three centuries past its influence has been essentially retrograde, and has gradually, but radically, decayed. The causes of its decline are various; but the chief present-day antagonist to the theological polity is the scientific spirit, and the scientific spirit can now never be repressed.
The metaphysical polity is progressive, but progressive mainly in a negative way. So far, it has made for progress; but it has made for progress chiefly by removing impediments to progress, by destroying the theological conceptions which retarded the development of human intelligence and human society. Though dangerous and revolutionary, it has been necessary; for much required to be demolished to permit permanent reconstruction.
The metaphysical polity was required to combat the theological; but now it has served its destructive purpose, and tends to become obstructive, for, having destroyed the old, it will not permit the new. Its chief dogma has always been liberty of conscience with the liberty of press and speech which that implies; but liberty of conscience really means little more than absence of intellectual regulation; and even as liberty of conscience is out of the question in astronomy and chemistry, so it is out of the question in social physics. Liberty of conscience and inquiry can only be temporary and transitional, and must be followed by positive decision on the part of those qualified to decide. It cannot be held that every man is competent to form opinions in social and political questions; it cannot be maintained that intellects of weak capacity can judge obscure and complex questions, and that all opinions are equally valuable. All society is based on faith in the opinion of others and in reciprocal confidence. Continual discussion of the foundations of society must render it impossible to lay sure foundations firm, and the disorder produced by free opinions on all points by all people is seen in the fierce and feeble sectarianism of Protestantism. What are the limits of free inquiry we shall see later; meantime, we may note that fine motto of the Catholic Church: "In necessary things, unity; in doubtful things, liberty; and in all things, charity."
The second dogma of the metaphysical polity is equality, and, like the other dogma, it must be considered the temporary expression of a temporary need. It is indeed a corollary of the dogma of liberty of conscience; for to assume liberty of conscience without equality of intelligence would be to stultify the assumption. Having achieved its purpose, it also became an obstacle in the path of progress. Equality sufficient to permit a man to use his faculties aright is allowed by all; but men cannot be made equal physically, and much less can they be made equal intellectually and morally.
The dogma of liberty of conscience and equality resulted naturally in a third dogma, the sovereignty of the people. This also was provisionally useful, in that it permitted a series of political experiments; but it is in essence revolutionary, condemning the superior to be ruled by the inferior. A fourth dogma, the dogma of national independence, has also been serviceable in separating the nations in preparation for a new union.
The metaphysical polity fails utterly in constructive capacity. During the first French revolution it successfully destroyed the old social system; but its attempts to reorganise society were retrogressive. Instead of Catholicism it proposed polytheism; and in the name of virtue and simplicity it condemned industry and art. Even science was condemned as aristocracy of knowledge. Nor can these blunders be considered accidental; they were inherent in the polity. It is evident that a polity that admits on the one hand the need for a theological foundation, and on the other hand destroys the foundations of theology must end in intellectual anarchy.
Satisfied with neither the theological nor the metaphysical polities, society has wavered between them, and the one tendency has served chiefly to counteract the other. Out of these oscillations a third school of political opinion, which we may call the "stationary school," has arisen.
