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.
