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. UNITY OF ALL BEINGS IMPLIED BY SYMPATHY, LOVE, AND MAGIC ENCHANTMENT. 3. On the other hand, observation teaches us that we sympathize with each other, that we cannot see the suffering of another man without sharing it, that we are naturally inclined to confide in each other, and to love; for love is a fact whose origin is connected with the question that occupies us. Further, if enchantments and magic charms mutually attract individuals, leading distant persons to sympathize, these effects can only be explained by the unity of soul. (It is well known that) words pronounced in a low tone of voice (telepathically?) affect a distant person, and make him hear what is going on at a great distance. Hence appears the unity of all beings, which demands the unity of the Soul. WHAT OF THE DIFFERENCES OF RATIONALITY, IF THE SOUL BE ONE? If, however, the Soul be one, why is some one soul reasonable, another irrational, or some other one merely vegetative? The indivisible part of the soul consists in reason, which is not divided in the bodies, while the part of the divisible soul in the bodies (which, though being one in herself, nevertheless divides herself in the bodies, because she sheds sentiment everywhere), must be regarded as another power of the soul (the sensitive power); likewise, the part which fashions and produces the bodies is still another power (the vegetative power); nevertheless, this plurality of powers does not destroy the unity of the soul. For instance, in a grain of seed there are also several powers; nevertheless this grain of seed is one, and from this unity is born a multiplicity which forms a unity. THE POWERS OF THE SOUL ARE NOT EXERCISED EVERYWHERE BECAUSE THEY DIFFER.
