category of being. For according to the science of logic it is certain that if an intrinsic quality is observed in a single individual, the existence of that quality may be assumed in all individuals. Because it is intrinsic. If it is intrinsic, it will be present in each individual. Whereas the indications based on not one but on innumerable observations beyond calculation and count, and the signs pointing to the immortality of spirits are so definite, that like for us there is a place called the New World, that is, America, and that human beings are found there, we can in no way doubt the existence of those people. In the same way, it is unacceptable to doubt that the spirits of those who have died are now present in great numbers in the World of the Inner Dimension of Things and in the Spirit World, and that they have relations with us. Our immaterial gifts go to them, and their luminous emanations come to us.

Moreover, with certain intuition, one may perceive with one’s conscience that a fundamental aspect of man continues after his death. And that fundamental aspect is spirit. As for spirit, it is not subject to destruction and dissolution. This is because it is simple and uncompounded, it has unity. As for destruction, dissolution, and decomposition, they are the function of complex and compound substances. As we explained above, life ensures a form of unity within multiplicity; it causes a sort of permanence. That is to say, unity and permanence are fundamental to spirit, from which they spread to multiplicity.
