If, by the term noumenon, we understand a thing so far as it is not an object of our sensuous intuition, thus making abstraction of our mode of intuiting it, this is a noumenon in the negative sense of the word.
What, therefore, we call noumenon must be understood by us as such in a negative sense.
The noumenon is a bit difficult to locate; it can be apprehended only be a process of reasoning -- which is a phenomenon.
Behind the phenomena of human history, the noumenon is the Human
And we cannot call a noumenon an object of pure thought; for the representation thereof is but the problematical conception of an object for a perfectly different intuition and a perfectly different understanding from ours, both of which are consequently themselves problematical.
Some hold that the universal nature of things of any kind is an Idea existing (apart from the things) in the intelligible world, invisible to mortal eye and only accessible to thought; whence the Idea is called a noumenon: that only the Idea is truly real, and that the things (say, trees, bedsteads and cities) which appear to us in sense-perception, and which therefore are called phenomena, only exist by participating in, or imitating, the Idea of each kind of them.
Now the 'phænomenon' is in time, and an effect: but the 'noumenon' is not in time any more than it is in space.
Pure action, that is, the will, is a 'noumenon', and irreferable to time.
