FIRST ARTICLE [II-II, Q. 29, Art. 1]
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.
Obj. 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.
Obj. 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" (Isa. 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.
