How might the Scientist derive a law from a fact1

   2If it is true that Philosophy proposes above all that we take consciousness of our deepest inclinations, if it is true that by applying itself to the diverse workings and operations of the intellect it is able to go back to their origin and appreciate their value, the task of the scientist himself comes back in some way to the domain of philosophy. It cannot be a question here of the results of scientific research into the subject of such knowledge, since in the eyes of a philosophy of the intellect metaphysics has nothing to expect from science as it has nothing to do with it and because knowledge of the laws of relationship cannot in any way modify a speculation that has as its object the absolute. But the very principles of science, the laws that the intellect obeys unknowingly through scientific research, the internal necessity which governs its course in scientific testing, the nature of its reasonings and the value of its conclusions, here we have the true domain of philosophy, here we have scientific formalism the critique of which will be truly philosophical because in a certain measure it will be the same critique of the laws of the intellect.
   "The laws of our rational faculty", as Stuart Mill said, "like those of every other natural agency, are only learned by seeing the agent at work. The earlier achievements of science were made without the conscious observance of any scientific Method; and we should never have known by what process truth is to be ascertained, if we had not previously ascertained many truths. But it was only the easier problems which could be thus resolved: natural sagacity, when it tried its strength against the more difficult ones, failed altogether. ... We learn to do a thing in difficult circumstances, by attending to the manner in which we have spontaneously done the same thing in easier ones." But it is only onto the outside, the framework of their reasoning, that scientists bring this reflective intellect of which Stuart Mill speaks here. The essence, the law, the value escapes them. Also do we not see them multiply experiences, bring precision to the conditions for the production of a phenomenon with care and infinite meticulousness? But once the cause is isolated, once the connection is affirmed, immediately and without hesitation, with all his might, never doubting the enormous leap that he has made the idea perform, without examination, without placing in doubt for a moment the firm foundation of his conclusion, the scientist endows with inevitability, with universality the connection thus established, which he passes from fact to law.  The connection that he has taken so much trouble to state exactly, he conceives it as if he has not taken one step further and had not consequently any precautions to be taken into account nor to proceed with caution, by connecting together the two phenomena inevitably, indissolubly, upon all points in space, in every minute in time, throughout every human intelligence, and outside of themselves. Because this universal and inevitable connection is not for him a law of his intellect. It is a law of nature. The philosopher coming upon such reasoning might be astonished that the mind of the scientist applies so much authority, so much value, so much inevitability to the simple statement of an isolated connection between two facts. But the scientist does not relate the universal and inevitable character of the law that he has extracted to himself. For him it is of the same character as the laws of nature. What drives on his reasoning at that moment, is the idea at the back of the mind that has directed him without his knowing, the idea that there are in fact laws in nature, that the course of these laws is uniform, that the relationships between  cause and effect remain identical because they are universal and inevitable. Likewise does the scientist believe not that he is establishing laws between phenomena but that he is discovering them? Hardly has he stated a relationship between two phenomena than he thinks he has simply rediscovered it. He thinks that he has diminished by the same proportion his ignorance of the laws of nature, an ignorance that furnishes him with the same idea by the certainty that he has of the objective existence of these unknown laws. It is this certainty that philosophies can never explain which, under various names deny the identity or accordance of laws of nature with the laws of Thought. By assimilating to the laws of association the principle of scientific inference they disregard that crucial observation that instead of being certain as he always is at the first decisive experience, the scientist must, by virtue of their theory, believe in the probabilities that are multiplied mechanically by the number of experiences. By relaxing the strictness of this doctrine in order to adapt it more exactly to the reality of things, evolutionism merely demonstrates a stronger sense of the difficulties of phenomenism without removing them or doing anything other than recede into a very ancient past. But they do not seem to vanish into that past other than through a mirage of perspective and to subsist there entirely. That we add to the experience of the scientist the experience of the whole line of his predecessors, added upon through heredity, the difference between the probability of the experience and the certainty of the conclusion remain irreducible. A billion probabilities do not make a certainty. On the billion and first occasion when the effect might not follow the cause or occur without being preceded by it, such an association being totally subjective and unable to connect phenomena in nature, after a certain period of time it connects them in our minds. It must therefore be concluded that the inference of the scientist which goes beyond experience, may not be derived from it and is not a transformation of it. We must look at the Principle of Causality and the Principle of Laws that is derived from it and affirms only the permanence and the identity of causal relationships of the first Principle of the Intellect, not in the sense that they explain the most profound aspect of things, but in this other sense, that they form part of the intellect, are anterior to experience, and are certainly empty if it does not come to fill them, giving to it alone by applying to it its form, its value and its meaning. "One theory alone", argues M. Rabier, "is able to confer perfect certainty upon the principles of Reason, namely: absolute idealism... but it is non-demonstrable... who can deduce from any sort of category of reason the flavour of the truffle, which in any case man, the animal of reason, is not alone in appreciating... How to explain that the idea becomes the phenomenon, category the sensation. " Without attempting here the defense of absolute idealism, it might be said that scientific certainty is in no way dependent upon the identity of the phenomenon and the idea, but upon the identity of laws that govern phenomena and the laws of the intellect. "Besides", Monsieur Rabier adds, "where can we find the proof of this absolute certainty that is claimed for the principle of inference? Is it in Kant's theory? it postulates agreement between reason and phenomena. A singular exigency in truth that disdains proof drawn from the teachings of clearly understood experience and which, in order to confer greater certainty to principles of alleged reason, what? a postulate! - We should not however let go of the prey for the shadow." For us who need Science to have all the certainty that the intellect of the scientist attributes to it, we should not be surprised that it remains, in the final analysis, dependent upon a postulate. Which comes back quite simply to saying that all philosophy is one and that Kant could not have created his logic of Understanding without attaching it, which is to say making it dependent upon, his Metaphysics.

The teacher Alphonse Darlu (professor of philosophy at the Lycée Condorcet) has written on the paper: "4/20 Extremely vague and superficial. Hardly one idea expressed in a very complex subject! - Some progress in composition."
