The truth is that the declarations which involve problems are converted very easily into vulgar paradoxes in the heads of those who are not accustomed to triumph over the difficulties of thought by the methodical use of appropriate means. I shall speak here, in general terms, of these problems, but, as it were, by aphorisms; and certainly I do not propose to write an encyclopedia in this short essay. And first of all, ethics. I do not mean systems and catechisms, religious or philosophic. Both of these have been and are above the ordinary and profane course of human events in most cases, as Utopias are above things. Neither do I speak of those formal analyses of ethical relations, which have been elaborated from the Sophists down to Herbart. This is science and not life. And it is formal science, like logic, geometry and grammar. The one who latest and with so much profundity defined these ethical relations (Herbart), knew well that ideas, that is to say, the formal points of view of the moral judgment, are in themselves powerless. Therefore he put into the circumstances of life and into the pedagogic formation of character the reality of ethics. He might have been taken for Owen if he had not been a retrograde. I am speaking of that ethics which exists prosaically and in an empirical and current fashion, in the inclinations, the habits, the customs, the counsels, the judgments and the appreciations of ordinary mortals. I am speaking of that ethics which as suggestion, as impulse and as bridle, appears in different degrees of development, and more or less unmistakably, although in a fragmentary fashion, among all men; by the very fact of association because each occupies a definite position in the association, they naturally and necessarily reflect upon their own works and the works of others, and they conceive obligations and appreciations and all the first elements of general precepts. There is the _factum_; and what is most important is that this _factum_ appears to us varied and multiple in the different conditions of life, and variable through history. This _factum_ is the _datum_ of research. Facts are neither true nor false, as Aristotle already knew. Systems, on the contrary, theologic or rational, may be true or false because they aim to comprehend, explain and complete the fact, by bringing that fact to another fact, or integrating it with another. Some points of preliminary theory are henceforth settled, in all that concerns the interpretation of this _factum_. The will does not choose of itself, as was supposed by the inventors of _free will_, that product of the impotency of the psychological analysis not yet arrived at maturity. Volitions, in so far as they are facts of consciousness, are particular expressions of the psychic mechanism. They are a result, first of necessities, and then, of all that precedes them up to the very elementary organic impulse.
