Draw a distinction.
Call it the first distinction.
Call the space in which it is drawn the space severed or cloven by the distinction.
Nothing, in fact, is far away from anything; things are not remote: there is, no doubt, the aloofness of difference and of mingled natures as against the unmingled; but selfhood has nothing to do with spatial position, and in unity itself there may still be distinction.
We find from time to time that the wisdom found in one field of study is applicable to another. George Spencer-Brown was writing about the space of logical and mathematical construction; Plotinus was speaking of unity on the most fundamental level, that of all things in the One. Taking these together, we see that every distinction between things is simultaneously a line of contact between them. That which we cleave apart, conceptually speaking, we necessarily and in the very same instance cleave together. Every separation is thus a connection. Such a line, of boundary as well as contact, not only cleaves a given space but is a space in itself, an interval or betweenness which has been called metaxy.
