Essential correlation is the specific and completely universal phase in which things appear. Everything that exists stands in correlation, and this correlation is the veritable nature of every existence. The existent thing in this way has no being of its own, but only in something else: in this other however it is self-relation; and correlation is the unity of the self-relation and relation-to-others. The relation of the whole and the parts is untrue to this extent, that the notion and the reality of the relation are not in harmony. The notion of the whole is to contain parts: but if the whole is taken and made what its notion implies, _i.e._ if it is divided, it at once ceases to be a whole. Things there are, no doubt, which correspond to this relation: but for that very reason they are low and untrue existences. We must remember however what 'untrue' signifies. When it occurs in a philosophical discussion, the term 'untrue' does not signify that the thing to which it is applied is non-existent. A bad state or a sickly body may exist all the same; but these things are untrue, because their notion and their reality are out of harmony. The relation of whole and parts, being the immediate relation, comes easy to reflective understanding; and for that reason it often satisfies when the question really turns on profounder ties. The limbs and organs, for instance, of an organic body are not merely parts of it: it is only in their unity that they are what they are, and they are unquestionably affected by that unity, as they also in turn affect it. These limbs and organs become mere parts, only when they pass under the hands of the anatomist, whose occupation, be it remembered, is not with the living body but with the corpse. Not that such analysis is illegitimate: we only mean that the external and mechanical relation of whole and parts is not sufficient for us, if we want to study organic life in its truth. And if this be so in organic life, it is the case to a much greater extent when we apply this relation to the mind and the formations of the spiritual world. Psychologists may not expressly speak of parts of the soul or mind, but the mode in which this subject is treated by the analytic understanding is largely founded on the analogy of this finite relation. At least that is so, when the different forms of mental activity are enumerated and described merely in their isolation one after another, as so-called special powers and faculties.
