Source digest

The preface’s account of petites perceptions: the roar of the sea is heard only because the noise of each wave is perceived a little, “puisque cent mille riens ne sauroient faire quelque chose”; noticeable perceptions come by degrees from ones too small to be noticed. The same pages restate the law of continuity, first published in the Nouvelles de la République des Lettres (1687): nature makes no leaps, and a motion never arises from rest or returns to it except through a smaller motion. Insensible variations make two individuals never perfectly alike. For this project it supplies the graded, additive reading of discernibility used in the continuity note.
