41. The prayer is answered by the mere fact that part and other part are wrought to one tone like a musical string which, plucked at one end, vibrates at the other also. Often, too, the sounding of one string awakens what might pass for a perception in another, the result of their being in harmony and tuned to one musical scale; now, if the vibration in a lyre affects another by virtue of the sympathy existing between them, then certainly in the All — even though it is constituted in contraries — there must be one melodic system; for it contains its unisons as well, and its entire content, even to those contraries, is a kinship.
Thus, too, whatever is hurtful to man — the passionate spirit, for example, drawn by the medium of the gall into the principle seated in the liver — comes with no intention of hurt; it is simply as one transferring fire to another might innocently burn him: no doubt, since he actually set the other on fire he is a cause, but only as the attacking fire itself is a cause, that is by the merely accidental fact that the person to whom the fire was being brought blundered in taking it.
