FUNCTION

[A68/B93] Contrasted by Kant to affections, connected with our ability to employ concepts; "whereas all intuitions, as sensible, rest on affectations, concepts rest on functions. By `function' I mean the unity of the act of bringing various representations under one common representation." Kant adds in explanation "concepts are based on spontaneity of thought, sensible intuitions on the receptivity of impressions", suggesting for Kant a function is any use of our power of spontaneity.
