Under the name of progress Comte understands a “social advance towards a definite although never attained termination, by a series of necessarily determined stages.” This idea was never clearly defined in antiquity.[262] The men of ancient times were more inclined to represent social movements as oscillatory or circular. Upon special points, for instance in morals, they had a foreshadowing of the idea of progress.[263] They conceived an effort towards improvement. But the scientific idea of social progress in its entirety remained foreign to them. For this idea is only formed by observation and by the analysis of history. Their historical outlook was yet too narrow for such a suggestion.
The idea of progress appears with the philosophy of history taught by Christianity; for, this religion gives a rational explanation of universal history considered as a whole. It proclaims the superiority of the Christian world over the pagan world, and of the new law over the old.[264] But, scarcely has the idea of progress thus come into existence when it becomes clouded over and tends to fade away. Catholicism clearly sees progress in the series of events which caused it to succeed a former state, but it denies the progress which continues from that moment. It considers itself as final. It “limits onward progress to the advent of Christianity.” It claims to fix an invariable dogma which contains immutable and absolute truth. This is the very negation of the positive idea of progress. In order to find this idea clearly conceived and scientifically formulated, we must come to Condorcet, and even to the XIX. century, that is to say, to the foundation of social science by Comte. He was especially led to it, he says, by the historical study of the development of the sciences. For, of all the social series, this is the one whose evolution is most advanced. No other suggests so clearly the idea of a “progression” whose terms succeed each other by virtue of a necessary filiation. Pascal already gave a very fine formula of it, in his Préface du Traité du Vide. Is it not remarkable that, in his sketch of the positive idea of progress, he should have been led at once to the essential hypothesis of social dynamics, that is to say, to consider the whole succession of generations as a single man, always living, continually learning?[265]
Nevertheless, the idea of progress, so well applied to the evolution of the sciences in the XVII. century, could not then be extended to all social facts. It had met with an insurmountable obstacle in the Middle Ages. Men considered that period as one of retrogression and barbarism, although, as a matter of fact, it was “characterised by the universal perfecting of human sociability.” The idea of progress therefore remained a special one. Thus originated the quarrel of the Ancients and the Moderns[266] whose importance has not been sufficiently understood. The “eminent” Fontenelle and the “judicious” Perrault have very clearly shown in respect to intellectual activity generally considered, what Pascal had already established for science properly so-called.[267]
The XVIII. century was full of the idea of progress. But, failing to follow a positive method, it gave a false direction to this idea. It believed in the indefinite perfectibility of man and of society. Now, this notion does not coincide with that of progress. It is even fundamentally opposed to it. Progress signifies “development subject to fixed conditions, and operating in virtue of necessary laws, which determine its advance and its limitations.” It is precisely the ignorance of these conditions and of these laws which gives rise to the idea of indefinite perfectibility. If Helvetius and Condorcet had had a positive knowledge of human nature, they would not have entertained so many illusions and unreasonable hopes. Biology, that is to say, scientific psychology, would have taught them that human nature is invariable in its basis, that the preponderance of the selfish over the altruistic instincts is essential to this nature, and that, if progress favours the development of the altruistic feelings, it cannot, however, overturn the natural equilibrium of our inclinations. In a word, indefinite perfectibility is a metaphysical idea. Imagination plays a greater part in it than observation. The philosophers who conceived it did not realise the relations which bind the intellectual and the moral life of man to the structure of his organism.
In order that the idea of progress should reach its final form it was necessary, in the first place, that positive psychology should have put an end to the dreams of indefinite perfectibility. It was also necessary that the French Revolution should come to render the course of the history of humanity intelligible. Indeed, according to Comte, a “progression” cannot be understood, so long as we do not know at least three of its terms. Two terms do not suffice to define it. Now, up to the time of the French Revolution, several “progressions” or social series undoubtedly offered the required number of terms to scientific reflection; for instance, the evolution of such and such a science or of such and such an art. But, in sociology, the knowledge of secondary laws is subordinated to that of primary laws, and the advance of such and such a social series can only be understood if the development of society in general is known in its fundamental law. To discover this law then, we must possess at least, three terms of the general “progression.” Now, before the French Revolution two terms only were given: the régime of the societies of antiquity, and the Christian régime (that is to say, the one which attained its highest degree of perfection in the Catholic organisation of the Middle Ages.) The French Revolution came to furnish the third term. It brought the idea of a new régime. As Kant had said, in terms which were certainly unknown to Comte, it gave men the idea of a social organisation founded upon principles different from those of the existing societies. Henceforth the idea of progress could apply itself to the whole of the historical development of humanity. “It is to this salutary disturbance,” says Comte, “that we owe the strength and the audacity to conceive a notion upon which rests the whole of social science, and consequently the whole of positive philosophy, of which this final science alone could constitute the unity.”[268]
This social science remained to be constructed. It will be the special work of Auguste Comte. According to him, the French Revolution only brought an imperfect idea of social progress. It helped to bring about the conception of the idea of a different régime, but without actually founding it. The functions of the new philosophy will be to realise the positive idea of social progress. In a word, the revolutionary impulse made this philosophy possible. It has not done away with its utility.[269]

Sociology being an abstract and speculative science in the same way as the other fundamental sciences, progress in it is not understood in a utilitarian or moral sense. From 1826 Comte exerted himself to prevent any equivocation on this point. The insufficiency of language, he says, obliges him to make use of the words “improvement” and “development,” of which the former and even the latter, although clearer, recalls ideas of absolute good and of indefinite amelioration, which Comte has no intention of expressing. These words for him have the simple scientific object of indicating, in social physics, a certain succession of states of the human species, “being effected according to determined laws: a usage exactly analogous to the one which physiologists make of them in the study of the individual organism, to indicate a succession of transformations with which no idea of continuous amelioration or deterioration is connected.”[270] It would be easy to treat of the whole of social physics without once using the word improvement, and always replacing it by the scientific term development. For the question is not to appreciate the respective value of successive states referred to an ideal state, but simply to establish the laws of their succession. “The present is full of the past and big with the future.” Liebnitz’s formula thus expresses the general idea of progress. Comte only makes it positive by discovering the general laws of this progress, and by showing that they are correlated to the laws of social statics.
As a matter of fact, does the development of humanity lead to improvement or progress, in the moral and practical sense of the word? Social science has not to answer this question. However, Comte thinks that this improvement takes place, and that progress, so understood, can be shown at once in our condition and in our nature.[271] As proofs of this, in the first place, he gives the increase in the population, at least in that portion of humanity which he nearly always considers alone, the white race; then he mentions the law—according to which exercise perfects the organs. This progress is fixed by heredity. Comte thus admits this principle laid down by Lamarck, with this reservation, that evolution never transforms “natural dispositions.”
