The concept of noumenon i.e., of a thing that is not to be thought at all as an object of the senses but is to be thought...as a thing in itself...[is] only a boundary concept serving to limit the pretension of sensibility [the senses].
Immanuel Kant (1787)

Blumenau’s useful summary introduction appeared in Philosophy Now March/April 2001 p.18. The older Kemp Smith translation of the Kant passage runs: “The concept of a noumenon–that is, of a thing which is not to be thought as object of the senses but as a thing in itself...[is]...a merely limiting concept, the function of which is to curb the pretensions of the sensibility;”
