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. _______________________
FIFTH ARTICLE [I, Q. 89, Art. 5]
Whether the Habit of Knowledge Here Acquired Remains in the Separated
Soul?
Objection 1: It would seem that the habit of knowledge acquired in this life does not remain in the soul separated from the body: for the Apostle says: "Knowledge shall be destroyed" (1 Cor. 13:8).
Obj. 2: Further, some in this world who are less good enjoy knowledge denied to others who are better. If, therefore, the habit of knowledge remained in the soul after death, it would follow that some who are less good would, even in the future life, excel some who are better; which seems unreasonable.
Obj. 3: Further, separated souls will possess knowledge by influence of the Divine light. Supposing, therefore, that knowledge here acquired remained in the separated soul, it would follow that two forms of the same species would co-exist in the same subject which cannot be.
Obj. 4: Further, the Philosopher says (Praedic. vi, 4, 5), that "a habit is a quality hard to remove: yet sometimes knowledge is destroyed by sickness or the like." But in this life there is no change so thorough as death. Therefore it seems that the habit of knowledge is destroyed by death.
On the contrary, Jerome says (Ep. liii, ad Paulinum), "Let us learn on earth that kind of knowledge which will remain with us in heaven."
I answer that, Some say that the habit of knowledge resides not in the intellect itself, but in the sensitive powers, namely, the imaginative, cogitative, and memorative, and that the intelligible species are not kept in the passive intellect. If this were true, it would follow that when the body is destroyed by death, knowledge here acquired would also be entirely destroyed.
But, since knowledge resides in the intellect, which is "the abode of species," as the Philosopher says (De Anima iii, 4), the habit of knowledge here acquired must be partly in the aforesaid sensitive powers and partly in the intellect. This can be seen by considering the very actions from which knowledge arises. For "habits are like the actions whereby they are acquired" (Ethic. ii, 1). Now the actions of the intellect, by which knowledge is here acquired, are performed by the mind turning to the phantasms in the aforesaid sensitive powers. Hence through such acts the passive intellect acquires a certain facility in considering the species received: and the aforesaid sensitive powers acquire a certain aptitude in seconding the action of the intellect when it turns to them to consider the intelligible object. But as the intellectual act resides chiefly and formally in the intellect itself, whilst it resides materially and dispositively in the inferior powers, the same distinction is to be applied to habit.
