And so neither is political economy a science yet, nor, so far, are economists men of science. Originally being nearly all barristers or men of letters, they were strangers to the idea of scientific observation, to the precise notion of a natural law, and finally to the sense of what constitutes a demonstration. If we make an exception of Adam Smith and of a few others, how could they apply the positive method which they did not know to the most difficult cases of analysis? Destutt de Tracy placed political economy between logic and ethics. And this was not without reason: for it is nearer to metaphysics than to positive science. In it, work preserves its personal character, schools contend with each other, the discussions as to the elementary notions of value, of utility, etc., savour of scholasticism. The very idea of studying economical phenomena separately is not scientific, since the various “social series” are interdependent, and since in sociology more particular laws depend upon more general laws.[340] There is no scientific study of economical facts unless we first look at them from the sociological point of view. We can no more isolate the laws which regulate the material existence of societies than we can describe man as an essentially calculating being, only actuated by the motive of personal interest. The same objections naturally hold good against the adversaries of the economists, since, in general, socialists and communists have confined themselves to an analogous conception of their science. However, while criticising them, Comte recognises the fact that they have established some truths. Everything they say is not false. Thus, they justly claim the right for the government to intervene in economical relations. And, if it be absurd to wish to abolish private property, as certain sects demanded, it is very true that property is of a social nature, and that it is necessary to regulate it.[341] To endow it with an absolute character is, says Comte, an “anti-social” theory. No property can be created, nor even transmitted, by its mere possessor without the concurrence of society. Thus always and everywhere the community has intervened in the exercise of the right of property. The tax makes the public a partner in every private fortune.
