 Just as all events must “take place” somewhere, all beings must be situated in some place. Beings always exist in relation to other beings, and any relation requires a third term, namely, the place or medium wherein they are related. In other words, for A and B to be related, there must be some place, C, in which their relation is situated. To begin with, we can understand this C as the spatial “context” in which objects are situated in relation to one another. But the context in which things are defined is more than spatial; a thing is not only here as opposed to there. Things are determined according to a number of criteria, each of which operates within its own field of judgment. Hence, the place C can be further understood as a “category” of judgment, such as the quality “color.” Red and blue are revealed, and contrasted with one another, as colors within the same color field.
