THE UNITY OF THE PRINCIPLE OF SEVERAL SOULS NEED NOT IMPLY THEIR BEING IDENTICAL.
2. In the first place, if the souls of myself and of another man form but one soul, this does not necessarily imply their being identical with their principle. Granting the existence of different beings, the same principle need not experience in each the same affections. Thus, humanity may equally reside in me, who am in motion, as in you, who may be at rest, although in me it moves, and it rests in you. Nevertheless, it is neither absurd nor paradoxical to insist that the same principle is both in you and in me; and this does not necessarily make us feel the identical affections. Consider a single body: it is not the left hand which feels what the right one does, but the soul which is present in the whole body. To make you feel the same as I do, our two bodies would have to constitute but a single one; then, being thus united, our souls would perceive the same affections. Consider also that the All remains deaf to a multitude of impressions experienced by the parts of a single and same organism, and that so much the more as the body is larger. This is the state of affairs, for instance, with the large whales which do not feel the impression received in some one part of their body, because of the smallness of the movement.
SYMPATHY DOES NOT FORCE IDENTITY OF SENSATION.
It is therefore by no means necessary that when one member of the universe experiences an affection, the latter be clearly felt by the All. The existence of sympathy is natural enough, and it could not be denied; but this does not imply identity of sensation. Nor is it absurd that our souls, while forming a single one should be virtuous and vicious, just as it would be possible that the same essence be at motion in me, but at rest in you. Indeed, the unity that we attribute to the universal (Soul) does not exclude all multiplicity, such a unity as befits intelligence. We may however say that (the soul) is simultaneously unity and plurality, because she participates not only in divisible essence in the bodies, but also in the indivisible, which consequently is one. Now, just as the impression perceived by one of my parts is not necessarily felt all over my body, while that which happens to the principal organ is felt by all the other parts, likewise, the impressions that the universe communicates to the individual are clearer, because usually the parts perceive the same affections as the All, while it is not evident that the particular affections that we feel would be also experienced by the Whole.
