 As objects of knowledge, appearances are continuous extensive magnitudes, but as objects of sensation or perception they are, according to Kant, intensive magnitudes. By an intensive magnitude Kant means a magnitude possessing a degree and so capable of being apprehended by the senses: for example brightness or temperature. Intensive magnitudes are entirely free of the intuitions of space or time, and “can only be presented as unities”. But, like extensive magnitudes, they are continuous. Moreover, appearances are always presented to the senses as intensive magnitudes.
