Editorial note — Page 368 CHAPTER XIV

[Footnote 1: Poincaré notes also the opposite tendency, for science to grow more complex. As he says: "And Newton's law itself? Its simplicity, so long undetected, is perhaps only apparent. Who knows whether it is not due to some complicated mechanism, to the impact of some subtile matter animated by irregular movements, and whether it has not become simple only through the action of averages and of great numbers? In any case it is difficult not to suppose that the true law contains complementary terms, which would become sensible at small distances." (Foundations of Science, p. 132.)]
