LINE, LIGHT, MAGNETISM. 124. While the point expands, it is active; this active expansion is a simple repetition of the point, and this is a _Line_, which in the sphere, however, is a _Radius_. With time originates not merely a series of numbers, but together with it also the line. The line and time are of one kind, repeated positions of the nothing, of the point. It is consequently clear, how that time were a repeated positing of the Eternal itself: for the line is only a repeated self-positing of the point, of the nothing. God fluctuating in his eternity, and the point, are one in kind; but God acting is a line, being or existing a sphere, i. e. the point in the act of being. 125. The line is nothing new in creation, but time itself, when regarded more closely. God creates the line as little as he does time; but this originates unto him, while he moves, while he thinks. It is impossible to think without producing a line. The line is therefore from eternity, is a series of numbers. 126. The essence of the line does not consist in its two extremities being continued with equal significance into the Infinite; but in its _radiality_, i. e. that one extremity turned towards the centre has become central, converging, absolute; but the other turned towards the periphery has become divergent, finite, multiplicity. The primary line is a line produced with two antagonized characters. The central extremity is 0, the peripheral is the bisected zero = ±. This radial line gives us the antetype of a new polarity. The two extremities are not related as + and-towards each other, but as 0 and +-. At the instant, when a line originates in the universe, it is not a line merely, or an indefinite line that originates; but one that is definite at both extremities, polar, indeed, but after a determinate fashion. Nothing, not even a finite thing, exists in an indefinite manner. 127. There is no mathematically straight line in the world: all real lines are polar; they are all rooted in God by one extremity, by the other in finitude. The primary act becomes in its first operation not merely a posited nothing, a numerical series; not merely time, not merely an aoristic line, but a _Linea determinata_; in short, God can step forth into time only as radius. The _Monas determinata_ is a _Monas radialis_, or a centroperipheric monas. 128. The essence of the primary antagonism is a centroperipheric antagonism. As centre is related to periphery, so is here one pole related to the other. Polar existence and central or peripheral existence are one. Primary polarity is centroperiphery. The primary line is constantly in a state of polar action, which is called _tension_; for it is always converging and diverging, at once central and peripheric. Every line originates, therefore, only by tension, and is only by it, yea, every line is nothing else than this tension.
