To this the answer would be: “Theoretically, so long as one confronts the problem from the mechanistic standpoint, that is, from the standpoint that deals only with reactions, it is attuned in places innumerable.” In exactly the same way a drop of water, as it trickles downward, theoretically can have innumerable points as its resting-place; practically, however, it will have one single resting-place, and this latter will prove itself the resting-place and the one single resting-place among countless possibilities simply and solely by the fact that the drop comes to a halt just at this spot. Actuality is simple as singly determined. It only becomes complex in the mechanistic mode of apprehending it; that is, where reactions alone are dealt with. Again, it may be asked: “Could not two Kammas attune themselves to one and the same body of material?” But this question has just as much meaning as if one asked, “Could not two men appropriate to themselves, assimilate, and be nourished by, the same loaf of bread?” So long as one treats of “bread” in purely theoretical fashion, eats concepts, well and good! But if one eats in actuality, the absurdity becomes obvious. Again: “Might it not happen for once that the ovum should conduct the lightning without the assistance of the sperm-cell?” So far as mankind is concerned, the only reply is that here both factors are required. It simply is so! Why are certain reactions brought about only when certain catalytic agents or ferments are introduced? How weighty the above objection has always been to the mind of mankind is shown by the important rôle which “immaculate conception” has played from the earliest times. That in itself it is not impossible the animal kingdom sufficiently attests. With man, however, the conditions are so disposed that both, ovum- and sperm-cell, are required in order to conduct the Kamma and cause it to take hold.
