1. Among those who believe in Prophecy, and even among our coreligionists, there are some ignorant people who think as follows: God selects any person He pleases, inspires him with the spirit of Prophecy, and entrusts him with a mission. It makes no difference whether that person be wise or stupid, old or young; provided he be, to some extent, morally good. For these people have not yet gone so far as to maintain that God might also inspire a wicked person with His spirit. They admit that this is impossible, unless God has previously caused him to improve his ways. 2. The philosophers hold that prophecy is a certain faculty of man in a state of perfection, which can only be obtained by study. Although the faculty is common to the whole race, yet it is not fully developed in each individual, either on account of the individual’s defective constitution, or on account of some other external cause. This is the case with every faculty common to a class. It is only brought to a state of perfection in some individuals, and not in all; but it is impossible that it should not be perfect in some individual of the class; and if the perfection is of such a nature that it can only be produced by an agent, such an agent must exist. Accordingly, it is impossible that an ignorant person should be a prophet; or that a person being no prophet in the evening, should, unexpectedly on the following morning, find himself a prophet, as if prophecy were a thing that could be found unintentionally. But if a person, perfect in his intellectual and moral faculties, and also perfect, as far as possible, in his imaginative faculty, prepares himself in the manner which will be described, he must become a prophet; for prophecy is a natural faculty of man. It is impossible that a man who has the capacity for prophecy should prepare himself for it without attaining it, just as it is impossible that a person with a healthy constitution should be fed well, and yet not properly assimilate his food; and the like.
