ANTICIPATION OF PERCEPTION

[A167/B209] (Associated by Kant with the categories of reality, negation, and limitation.) "All knowledge by means of which I am enabled to know and determine a priori what belongs to empirical knowledge may be entitled an anticipation". Sensation, as having essentially an intensive magnitude, cannot be so determined a priori; however, an anticipation of perception is possible because from the analysis of space and time as forms of intuitions we can make "pure determinations...in respect of shape as well as [extensive] magnitude".
