EARLY GREEK PHILOSOPHY

to separate the elements, nothing could ever arise from it. Empedokles accordingly assumed the existence of such a substance, and he gave it the name of Strife. But the effect of this would be to separate all the elements in the Sphere completely, and then nothing more could possibly happen; something else was needed to bring the elements together again. This Empedokles found in Love, which he regarded as the same impulse to union that is implanted in human bodies (fr. 17, 22 sqq.). He looks at it, in fact, from a physiological point of view, as was natural for the founder of a medical school. No mortal had yet marked, he says, that the very same Love men know in their bodies had a place among the elements.

The Love and Strife of Empedokies are no incorporeal forces. They are active, indeed, but they are still corporeal. At the time, this was inevitable; nothing incorporeal had yet been dreamt of. Naturally, Aristotle is puzzled by this characteristic of what he regarded as efficient causes. "The Love of Empedokles," he says,[1] "is both an efficient cause, for it brings things together, and a material cause, for it is apart of the mixture." And Theophrastos expressed the same idea by saying[2] that Empedokles sometimes gave an efficient power to Love and Strife, and sometimes put them on a level with the other four. The fragments leave no room for doubt that they were thought of as spatial and corporeal. All the six are called "equal." Love is said to be "equal in length and breadth" to the others, and Strife is described as equal to each of them in weight (fr.17).

The function of Love is to produce union; that of Strife, to break it up again. Aristotle, however, rightly points out that in another sense it is Love that divides and Strife that unites. When the Sphere is broken up by Strife, the result is that all the Fire, for instance, which was contained in it comes together and becomes one; and again, when the
