### Question. 43 - OF THE CAUSE OF FEAR (TWO ARTICLES)

We must now consider the cause of fear: under which head there are two points of inquiry:
(1) Whether love is the cause of fear?
(2) Whether defect is the cause of fear?

#### Art. 1 - Whether love is the cause of fear?

Objection 1: It would seem that love is not the cause of fear. For that which leads to a thing is its cause. But "fear leads to the love of charity" as Augustine says on the canonical epistle of John (Tract. ix). Therefore fear is the cause of love, and not conversely.
Objection 2: Further, the Philosopher says (Rhet. ii, 5) that "those are feared most from whom we dread the advent of some evil." But the dread of evil being caused by someone, makes us hate rather than love him. Therefore fear is caused by hate rather than by love.
Objection 3: Further, it has been stated above (Q[42], A[3]) that those things which occur by our own doing are not fearful. But that which we do from love, is done from our inmost heart. Therefore fear is not caused by love.
On the contrary, Augustine says (QQ. 83, qu. 33): "There can be no doubt that there is no cause for fear save the loss of what we love, when we possess it, or the failure to obtain what we hope for." Therefore all fear is caused by our loving something: and consequently love is the cause of fear.
I answer that, The objects of the soul's passions stand in relation thereto as the forms to things natural or artificial: because the passions of the soul take their species from their objects, as the aforesaid things do from their forms. Therefore, just as whatever is a cause of the form, is a cause of the thing constituted by that form, so whatever is a cause, in any way whatever, of the object, is a cause of the passion. Now a thing may be a cause of the object, either by way of efficient cause, or by way of material disposition. Thus the object of pleasure is good apprehended as suitable and conjoined: and its efficient cause is that which causes the conjunction, or the suitableness, or goodness, or apprehension of that good thing; while its cause by way of material disposition, is a habit or any sort of disposition by reason of which this conjoined good becomes suitable or is apprehended as such.
Accordingly, as to the matter in question, the object of fear is something reckoned as an evil to come, near at hand and difficult to avoid. Therefore that which can inflict such an evil, is the efficient cause of the object of fear, and, consequently, of fear itself. While that which renders a man so disposed that thing is such an evil to him, is a cause of fear and of its object, by way of material disposition. And thus it is that love causes fear: since it is through his loving a certain good, that whatever deprives a man of that good is an evil to him, and that consequently he fears it as an evil.
Reply to Objection 1: As stated above (Q[42], A[1]), fear, of itself and in the first place, regards the evil from which it recoils as being contrary to some loved good: and thus fear, of itself, is born of love. But, in the second place, it regards the cause from which that evil ensues: so that sometimes, accidentally, fear gives rise to love; in so far as, for instance, through fear of God's punishments, man keeps His commandments, and thus begins to hope, while hope leads to love, as stated above (Q[40] , A[7]).
Reply to Objection 2: He, from whom evil is expected, is indeed hated at first; but afterwards, when once we begin to hope for good from him, we begin to love him. But the good, the contrary evil of which is feared, was loved from the beginning.
Reply to Objection 3: This argument is true of that which is the efficient cause of the evil to be feared: whereas love causes fear by way of material disposition, as stated above.

#### Art. 2 - Whether defect is the cause of fear?

Objection 1: It would seem that defect is not a cause of fear. Because those who are in power are very much feared. But defect is contrary to power. Therefore defect is not a cause of fear.
Objection 2: Further, the defect of those who are already being executed is extreme. But such like do not fear as stated in Rhet. ii, 5. Therefore defect is not a cause of fear.
Objection 3: Further, contests arise from strength not from defect. But "those who contend fear those who contend with them" (Rhet. ii, 5). Therefore defect is not a cause of fear.
On the contrary, Contraries ensue from contrary causes. But "wealth, strength, a multitude of friends, and power drive fear away" (Rhet. ii, 5). Therefore fear is caused by lack of these.
I answer that, As stated above (A[1]), fear may be set down to a twofold cause: one is by way of a material disposition, on the part of him that fears; the other is by way of efficient cause, on the part of the person feared. As to the first then, some defect is, of itself, the cause of fear: for it is owing to some lack of power that one is unable easily to repulse a threatening evil. And yet, in order to cause fear, this defect must be according to a measure. For the defect which causes fear of a future evil, is less than the defect caused by evil present, which is the object of sorrow. And still greater would be the defect, if perception of the evil, or love of the good whose contrary is feared, were entirely absent.
But as to the second, power and strength are, of themselves, the cause of fear: because it is owing to the fact that the cause apprehended as harmful is powerful, that its effect cannot be repulsed. It may happen, however, in this respect, that some defect causes fear accidentally, in so far as owing to some defect someone wishes to hurt another; for instance, by reason of injustice, either because that other has already done him a harm, or because he fears to be harmed by him.
Reply to Objection 1: This argument is true of the cause of fear, on the part of the efficient cause.
Reply to Objection 2: Those who are already being executed, are actually suffering from a present evil; wherefore their defect exceeds the measure of fear.
Reply to Objection 3: Those who contend with one another are afraid, not on account of the power which enables them to contend: but on account of the lack of power, owing to which they are not confident of victory.
