OF PEACE (FOUR ARTICLES)
We must now consider Peace, under which head there are four points of inquiry:
(1) Whether peace is the same as concord?
(2) Whether all things desire peace?
(3) Whether peace is an effect of charity?
(4) Whether peace is a virtue?
Whether peace is the same as concord?
Objection 1: It would seem that peace is the same as concord. For Augustine says (De Civ. Dei xix, 13): "Peace among men is well ordered concord." Now we are speaking here of no other peace than that of men. Therefore peace is the same as concord.
Objection 2: Further, concord is union of wills. Now the nature of peace consists in such like union, for Dionysius says (Div. Nom. xi) that peace unites all, and makes them of one mind. Therefore peace is the same as concord.
Objection 3: Further, things whose opposites are identical are themselves identical. Now the one same thing is opposed to concord and peace, viz. dissension; hence it is written ( 1 Cor. 16:33 ): "God is not the God of dissension but of peace." Therefore peace is the same as concord.
On the contrary, There can be concord in evil between wicked men. But "there is no peace to the wicked" ( Is. 48:22 ). Therefore peace is not the same as concord.
I answer that, Peace includes concord and adds something thereto. Hence wherever peace is, there is concord, but there is not peace, wherever there is concord, if we give peace its proper meaning.
For concord, properly speaking, is between one man and another, in so far as the wills of various hearts agree together in consenting to the same thing. Now the heart of one man may happen to tend to diverse things, and this in two ways. First, in respect of the diverse appetitive powers: thus the sensitive appetite tends sometimes to that which is opposed to the rational appetite, according to Gal. 5:17 : "The flesh lusteth against the spirit." Secondly, in so far as one and the same appetitive power tends to diverse objects of appetite, which it cannot obtain all at the same time: so that there must needs be a clashing of the movements of the appetite. Now the union of such movements is essential to peace, because man's heart is not at peace, so long as he has not what he wants, or if, having what he wants, there still remains something for him to want, and which he cannot have at the same time. On the other hand this union is not essential to concord: wherefore concord denotes union of appetites among various persons, while peace denotes, in addition to this union, the union of the appetites even in one man.
Reply to Objection 1: Augustine is speaking there of that peace which is between one man and another, and he says that this peace is concord, not indeed any kind of concord, but that which is well ordered, through one man agreeing with another in respect of something befitting to both of them . For if one man concord with another, not of his own accord, but through being forced, as it were, by the fear of some evil that besets him, such concord is not really peace, because the order of each concordant is not observed, but is disturbed by some fear-inspiring cause. For this reason he premises that "peace is tranquillity of order," which tranquillity consists in all the appetitive movements in one man being set at rest together.
Reply to Objection 2: If one man consent to the same thing together with another man, his consent is nevertheless not perfectly united to himself, unless at the same time all his appetitive movements be in agreement.
Reply to Objection 3: A twofold dissension is opposed to peace, namely dissension between a man and himself, and dissension between one man and another. The latter alone is opposed to concord.
Whether all things desire peace?
Objection 1: It would seem that not all things desire peace. For, according to Dionysius (Div. Nom. xi), peace "unites consent." But there cannot be unity of consent in things which are devoid of knowledge. Therefore such things cannot desire peace.
Objection 2: Further, the appetite does not tend to opposite things at the same time. Now many desire war and dissension. Therefore all men do not desire peace.
Objection 3: Further, good alone is an object of appetite. But a certain peace is, seemingly, evil, else Our Lord would not have said ( Mat. 10:34 ): "I came not to send peace." Therefore all things do not desire peace.
Objection 4: Further, that which all desire is, seemingly, the sovereign good which is the last end. But this is not true of peace, since it is attainable even by a wayfarer; else Our Lord would vainly command ( Mk. 9:49 ): "Have peace among you." Therefore all things do not desire peace.
On the contrary, Augustine says (De Civ. Dei xix, 12,14) that "all things desire peace": and Dionysius says the same (Div. Nom. xi).
I answer that, From the very fact that a man desires a certain thing it follows that he desires to obtain what he desires, and, in consequence, to remove whatever may be an obstacle to his obtaining it. Now a man may be hindered from obtaining the good he desires, by a contrary desire either of his own or of some other, and both are removed by peace, as stated above. Hence it follows of necessity that whoever desires anything desires peace, in so far as he who desires anything, desires to attain, with tranquillity and without hindrance, to that which he desires: and this is what is meant by peace which Augustine defines (De Civ. Dei xix, 13) "the tranquillity of order."
Reply to Objection 1: Peace denotes union not only of the intellective or rational appetite, or of the animal appetite, in both of which consent may be found, but also of the natural appetite. Hence Dionysius says that "peace is the cause of consent and of connaturalness," where "consent" denotes the union of appetites proceeding from knowledge, and "connaturalness," the union of natural appetites.
Reply to Objection 2: Even those who seek war and dissension, desire nothing but peace, which they deem themselves not to have. For as we stated above, there is no peace when a man concords with another man counter to what he would prefer. Consequently men seek by means of war to break this concord, because it is a defective peace, in order that they may obtain peace, where nothing is contrary to their will. Hence all wars are waged that men may find a more perfect peace than that which they had heretofore.
