Note 30 — Chapter II · System of all Principles of the Pure Understanding
J. M. D. (John Miller Dow) Meiklejohn translation
Kant’s meaning is: The two principles enunciated under the heads of “Axioms of Intuition,” and “Anticipations of Perception,” authorize the application to phenomena of determinations of size and number, that is of mathematic. For example, I may compute the light of the sun, and say that its quantity is a certain number of times greater than that of the moon. In the same way, heat is measured by the comparison of its different effects on water, &c., and on mercury in a thermometer.—Tr
