For the charge of Optimism there is even less ground than for that of Fatalism. The latter was, to a certain extent, connected with the rise of the Positive spirit; but Optimism is simply a result of Theology; and its influence has always been decreasing with the growth of Positivism. Astronomical laws, it is true, suggest the idea of perfection as naturally as that of necessity. On the other hand, their great simplicity places the defects of the Order of Nature in so clear a light, that optimists would never have sought their arguments in astronomy, were it not that the first elements of the science had to be worked out under the influence of Monotheism, a system which involved the hypothesis of absolute wisdom. But by the theory of development on which the Positive synthesis is here made to rest, Optimism is discarded as well as Fatalism, in the direct proportion of the intricacy of the phenomena. It is in the most intricate that the defects of Nature, as well as the power of modifying them, become most manifest. With regard, therefore, to social phenomena, the most complex of all, both charges are utterly misplaced. Any optimistic tendencies that writers on social subjects may display, must be due to the fact that their education has not been such as to teach them the nature and conditions of the true scientific spirit. For want of sound logical training, great misuse has been made in our own time of a property peculiar to social phenomena. It is that we find in them a greater amount of spontaneous wisdom than might have been expected from their complexity. It would be a mistake, however, to suppose this wisdom perfect. The phenomena in question are those of intelligent beings who are always occupied in amending the defects of their economy. It is obvious, therefore, that they will show less imperfection than if, in a case equally complicated, the agents could have been blind. The standard by which to judge of action is always to be taken relatively to the social state in which the action takes place. Therefore all historical positions and changes must have at least some grounds of justification; otherwise they would be totally incomprehensible, because inconsistent with the nature of the agents and of the actions performed by them. Now this naturally fosters a dangerous tendency to Optimism in all thinkers, who, whatever their powers may be, have not passed through any strict scientific training, and have consequently never cast off metaphysical and theological modes of thought in the higher subjects. Because every government shows a certain adaptation to the civilization of its time, they make the loose assertion that the adaptation is perfect; a conception which is of course chimerical. But it is unjust to charge Positivism with errors which are evidently contrary to its true spirit, and merely due to the want of logical and scientific training in those who have hitherto engaged in the study of social questions.
