FOURTH ARTICLE [I, Q. 89, Art. 4]

Whether the Separated Soul Knows Singulars?

Objection 1: It would seem that the separated soul does not know

singulars. For no cognitive power besides the intellect remains in

the separated soul, as is clear from what has been said above (Q. 77,

A. 8). But the intellect cannot know singulars, as we have shown (Q.

86, A. 1). Therefore the separated soul cannot know singulars.

Obj. 2: Further, the knowledge of the singular is more determinate

than knowledge of the universal. But the separated soul has no

determinate knowledge of the species of natural things, therefore

much less can it know singulars.

Obj. 3: Further, if it knew the singulars, yet not by sense, for the

same reason it would know all singulars. But it does not know all

singulars. Therefore it knows none.

_On the contrary,_ The rich man in hell said: "I have five brethren"

(Luke 16:28).

_I answer that,_ Separated souls know some singulars, but not all,

not even all present singulars. To understand this, we must consider

that there is a twofold way of knowing things, one by means of

abstraction from phantasms, and in this way singulars cannot be

directly known by the intellect, but only indirectly, as stated above

(Q. 86, A. 1). The other way of understanding is by the infusion of

species by God, and in that way it is possible for the intellect to

know singulars. For as God knows all things, universal and singular,

by His Essence, as the cause of universal and individual principles

(Q. 14, A. 2), so likewise separate substances can know singulars by

species which are a kind of participated similitude of the Divine

Essence. There is a difference, however, between angels and separated

souls in the fact that through these species the angels have a

perfect and proper knowledge of things; whereas separated souls have

only a confused knowledge. Hence the angels, by reason of their

perfect intellect, through these species, know not only the specific

natures of things, but also the singulars contained in those species;

whereas separated souls by these species know only those singulars to

which they are determined by former knowledge in this life, or by

some affection, or by natural aptitude, or by the disposition of the

Divine order; because whatever is received into anything is

conditioned according to the mode of the recipient.

Reply Obj. 1: The intellect does not know the singular by way of

abstraction; neither does the separated soul know it thus; but as

explained above.

Reply Obj. 2: The knowledge of the separated soul is confined to

those species or individuals to which the soul has some kind of

determinate relation, as we have said.

Reply Obj. 3: The separated soul has not the same relation to all

singulars, but one relation to some, and another to others. Therefore

there is not the same reason why it should know all singulars.
