De Principiis

⁵ Seeing, then, that these positions are thus established by a sort of natural evidence, is it not superfluous to throw back the causes of our actions on those things which happen to us from without, and thus transfer the blame from ourselves, on whom it wholly lies? For this is to say that we are like pieces of wood, or stones, which have no motion in themselves, but receive the causes of their motion from without. Now such an assertion is neither true nor becoming, and is invented only that the freedom of the will may be denied; unless, indeed, we are to suppose that the freedom of the will consists in this, that nothing which happens to us from without can incite us to good or evil. And if any one were to refer the causes of our faults to the natural disorder of the body, such a theory is proved to be contrary to the reason of all teaching. For, as we see in very many individuals, that after living unchastely and intemperately, and after being the captives of luxury and lust, if they should happen to be aroused by the word of teaching and instruction to enter upon a better course of life, there takes place so great a change, that from being luxurious and wicked men, they are converted into those who are sober, and most chaste and gentle; so, again, we see in the case of those who are quiet and honest, that after associating with restless and shameless individuals, their good morals are corrupted by evil conversation, and they become like those whose wickedness is complete. And this is the case sometimes with men of mature age, so that such have lived more chastely in youth than when more advanced years have enabled them to indulge in a freer mode of life. The result of our reasoning, therefore, is to show that those things which happen to us from without are not in our own power; but that to make a good or bad use of those things which do so happen, by help of that reason which is within us, and which distinguishes and determines how these things ought to be used, is within our power.

6. And now, to confirm the deductions of reason by the authority of Scripture— viz., that it is our own doing whether we live rightly or not, and that we are not compelled, either by those causes which come to us from without, or, as some think, by the presence of fate— we adduce the testimony of the prophet Micah, in these words: “If it has been announced to you, O man, what is good, or what the Lord requires of you, except that you should do justice, and love mercy, and be ready to walk with the Lord your God.” Moses also speaks as follows: “I have placed before your face the way of life and the way of death: choose what is good, and walk in it.” Isaiah, moreover, makes this declaration: “If you are willing, and hear me, you shall eat the good of the land. But if you be unwilling, and will not hear me, the sword shall consume you; for the mouth of the Lord has spoken this.” In the Psalm, too, it is written: “If My people had heard Me, if Israel had walked in My ways, I would have humbled her enemies to nothing;” by which he shows that it was in the power of the people to hear, and to walk in the ways of God. The Saviour also saying, “I say unto you, Resist not evil;” and, “Whoever shall be angry with his brother, shall be in danger of the judgment;” and, “Whosoever shall look upon a woman to lust after her, has already committed adultery with her in his heart;” and in issuing certain other commands—conveys no other meaning than this, that it is in our own power to observe what is commanded. And therefore we are rightly rendered liable to condemnation if we transgress those commandments which we are able to keep. And hence He Himself also declares: “Every one who hears my words, and does them, I will show to whom he is like: he is like a wise man who built his house upon a rock,” etc. So also the declaration: “Whoever hears these things, and does them not, is like a foolish man, who built his house upon the sand,” etc. Even the words addressed to those who are on His right hand, “Come unto Me, all you blessed of My Father,” etc.; “for I was an hungered, and you gave Me to eat; I was thirsty, and you gave Me drink,” manifestly show that it depended upon themselves, that either these should be deserving of praise for doing what was commanded and receiving what was promised, or those deserving of censure who either heard or received the contrary, and to whom it was said, “Depart, you cursed, into everlasting fire.” Let us observe also, that the Apostle Paul addresses us as having power over our own will, and as possessing in ourselves the causes either of our salvation or of our ruin: “Do you despise the riches of His goodness, and of His patience, and of His long-suffering, not knowing that the goodness of God leads you to repentance? But, according to your hardness and impenitent heart, you are treasuring up for yourself wrath on the day of judgment and of the revelation of the just judgment of God, who will render to every one according to his work: to those who by patient continuance in well-doing seek for glory and immortality, eternal life; while to those who are contentious, and believe not the truth, but who believe iniquity, anger, indignation, tribulation, and distress, on every soul of man that works evil, on the Jew first, and (afterwards) on the Greek; but glory, and honour, and peace to every one that does good, to the Jew first, and (afterwards) to the Greek.” You will find also innumerable other passages in holy Scripture, which manifestly show that we possess freedom of will. Otherwise there would be a contrariety in commandments being given us, by observing which we may be saved, or by transgressing which we may be condemned, if the power of keeping them were not implanted in us.
