Q: SECOND ARTICLE [II-II, Q. 173, Art. 2]

A: On the contrary,
It is written (Osee 12:10): "I have multiplied" their "visions, and I have used similitudes, by the ministry of the prophets." Now multiplicity of visions results, not from a diversity of intellectual light, which is common to every prophetic vision, but from a diversity of species, whence similitudes also result. Therefore it seems that in prophetic revelation new species of things are impressed, and not merely an intellectual light.

I answer that,
As Augustine says (Gen. ad lit. xii, 9), "prophetic knowledge pertains most of all to the intellect." Now two things have to be considered in connection with the knowledge possessed by the human mind, namely the acceptance or representation of things, and the judgment of the things represented. Now things are represented to the human mind under the form of species: and according to the order of nature, they must be represented first to the senses, secondly to the imagination, thirdly to the passive intellect, and these are changed by the species derived from the phantasms, which change results from the enlightening action of the active intellect. Now in the imagination there are the forms of sensible things not only as received from the senses, but also transformed in various ways, either on account of some bodily transformation (as in the case of people who are asleep or out of their senses), or through the coordination of the phantasms, at the command of reason, for the purpose of understanding something. For just as the various arrangements of the letters of the alphabet convey various ideas to the understanding, so the various coordinations of the phantasms produce various intelligible species of the intellect.

As to the judgment formed by the human mind, it depends on the power of the intellectual light.

Now the gift of prophecy confers on the human mind something which surpasses the natural faculty in both these respects, namely as to the judgment which depends on the inflow of intellectual light, and as to the acceptance or representation of things, which is effected by means of certain species. Human teaching may be likened to prophetic revelation in the second of these respects, but not in the first. For a man represents certain things to his disciple by signs of speech, but he cannot enlighten him inwardly as God does.

But it is the first of these two that holds the chief place in prophecy, since judgment is the complement of knowledge. Wherefore if certain things are divinely represented to any man by means of imaginary likenesses, as happened to Pharaoh (Gen. 41:1-7) and to Nabuchodonosor (Dan. 4:1-2), or even by bodily likenesses, as happened to Balthasar (Dan. 5:5), such a man is not to be considered a prophet, unless his mind be enlightened for the purpose of judgment; and such an apparition is something imperfect in the genus of prophecy. Wherefore some [*Rabbi Moyses, Doct. Perplex. II, xxxvi] have called this "prophetic ecstasy," and such is divination by dreams. And yet a man will be a prophet, if his intellect be enlightened merely for the purpose of judging of things seen in imagination by others, as in the case of Joseph who interpreted Pharaoh's dream. But, as Augustine says (Gen. ad lit. xii, 9), "especially is he a prophet who excels in both respects, so," to wit, "as to see in spirit likenesses significant of things corporeal, and understand them by the quickness of his intellect."

Now sensible forms are divinely presented to the prophet's mind, sometimes externally by means of the senses--thus Daniel saw the writing on the wall (Dan. 5:25)--sometimes by means of imaginary forms, either of exclusively Divine origin and not received through the senses (for instance, if images of colors were imprinted on the imagination of one blind from birth), or divinely coordinated from those derived from the senses--thus Jeremiah saw the "boiling caldron . . . from the face of the north" (Jer. 1:13)--or by the direct impression of intelligible species on the mind, as in the case of those who receive infused scientific knowledge or wisdom, such as Solomon or the apostles.

But intellectual light is divinely imprinted on the human mind--sometimes for the purpose of judging of things seen by others, as in the case of Joseph, quoted above, and of the apostles whose understanding our Lord opened "that they might understand the scriptures" (Luke 24:45); and to this pertains the "interpretation of speeches"--sometimes for the purpose of judging according to Divine truth, of the things which a man apprehends in the ordinary course of nature--sometimes for the purpose of discerning truthfully and efficaciously what is to be done, according to Isa. 63:14, "The Spirit of the Lord was their leader."

Hence it is evident that prophetic revelation is conveyed sometimes by the mere infusion of light, sometimes by imprinting species anew, or by a new coordination of species.

Reply Obj. 1: As stated above, sometimes in prophetic revelation imaginary species previously derived from the senses are divinely coordinated so as to accord with the truth to be revealed, and then previous experience is operative in the production of the images, but not when they are impressed on the mind wholly from without.

Reply Obj. 2: Intellectual vision is not effected by means of bodily and individual images, but by an intelligible image. Hence Augustine says (De Trin. ix, 11) that "the soul possesses a certain likeness of the species known to it." Sometimes this intelligible image is, in prophetic revelation, imprinted immediately by God, sometimes it results from pictures in the imagination, by the aid of the prophetic light, since a deeper truth is gathered from these pictures in the imagination by means of the enlightenment of the higher light.

Reply Obj. 3: It is true that man is able by his natural powers to form all kinds of pictures in the imagination, by simply considering these pictures, but not so that they be directed to the representation of intelligible truths that surpass his intellect, since for this purpose he needs the assistance of a supernatural light.
