Is consciousness then the momentary, the presencing, the immediate, the solitary? Only in that it is also a relation to the enduring, the absent, the distant, the general. It is open-ended relation to what it is not, it is positive and negative. It is truly the given in that it is a law unto itself or it is free from all law. If it arises in a way, in a mode, that it never shown before it is no less itself and requires no justification. If you think you know its boundaries then you don't know it at all.
