The relation of reason to fact, or eternity to time, like that of reﬂection to the unreﬂective, of thought to language or of thought to perception is this two way relationship that phenomenology has called Fundierung: the founding term, or originator time, the unreﬂective, the fact, language, perception is primary in the sense that the originated is presented as a determinate or explicit form of the originator, which prevents the latter from reabsorbing the former, and yet the originator is not primary in the empiricist sense and the originated is not simply derived from it, since it is through the originated that the originator is made manifest.
