““The same trend is noticeable in the scientific realm: research here is for its own sake far more than for the partial and fragmentary results it achieves; here we see an ever more rapid succession of unfounded theories and hypotheses, no sooner set up than crumbling to give way to others that will have an even shorter life - a veritable chaos amid which one would search in vain for anything definitive, unless it be a monstrous accumulation of facts and details incapable of proving or signifying anything. We refer here of course to speculative science, insofar as this still exists; in applied science there are on the contrary undeniable results, and this is easily understandable since these results bear directly on the domain of matter.””
