Of Peace

Of Peace — St. Thomas Aquinas asks: Whether peace is the same as concord?; Whether all things desire peace?; Whether peace is the proper effect of charity?; Whether peace is a virtue?.

We must now consider Peace, under which head there are four points of inquiry:

Article 1: Whether peace is the same as concord?

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.

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.

Article 2: Whether all things desire peace?

Augustine says (De Civ. Dei xix, 12,14) that "all things desire peace": and Dionysius says the same (Div. Nom. xi).

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."

Article 3: Whether peace is the proper effect of charity?

It is written (Ps. 118:165): "Much peace have they that love Thy Law."

Peace implies a twofold union, as stated above (). The first is the result of one's own appetites being directed to one object; while the other results from one's own appetite being united with the appetite of another: and each of these unions is effected by charity---the first, in so far as man loves God with his whole heart, by referring all things to Him, so that all his desires tend to one object---the second, in so far as we love our neighbor as ourselves, the result being that we wish to fulfil our neighbor's will as though it were ours: hence it is reckoned a sign of friendship if people "make choice of the same things" (Ethic. ix, 4), and Tully says (De Amicitia) that friends "like and dislike the same things" (Sallust, Catilin.)

Article 4: Whether peace is a virtue?

Virtue is not the last end, but the way thereto. But peace is the last end, in a sense, as Augustine says (De Civ. Dei xix, 11). Therefore peace is not a virtue.

As stated above (), when a number of acts all proceeding uniformly from an agent, follow one from the other, they all arise from the same virtue, nor do they each have a virtue from which they proceed, as may be seen in corporeal things. For, though fire by heating, both liquefies and rarefies, there are not two powers in fire, one of liquefaction, the other of rarefaction: and fire produces all such actions by its own power of calefaction.

Since then charity causes peace precisely because it is love of God and of our neighbor, as shown above (), there is no other virtue except charity whose proper act is peace, as we have also said in reference to joy ().
