Note 130 — Chapter V · EVOLUTION OF THE PRINCIPAL CONCEPTS. (continued 2)

Since our subject is the tracing out of the concept of law in its different degrees, starting from the generic image, we have no need to study the nature of the laws proper to each science (logic, mathematics, mechanics, physico-chemistry, biology, etc.), nor to discuss their value. For this point, see Boutroux, L’idée de loi naturelle dans la science et la philosophie contemporaine. Paris, 1895.
