II
At[21] last I see, what it was that you begged me not to publish. However, as it forms the chief foundation of everything in the treatise[22] which I intend to bring out, I should like briefly to explain here, in what sense I assert that a fatal necessity presides over all things and actions.
God I in no wise subject to fate: I conceive that all things follow with inevitable necessity from the nature of God, in the same way as every one conceives that it follows from God's nature that God understands Himself. This latter consequence all admit to follow necessarily from the divine nature, yet no one conceives that God is under the compulsion of any fate, but that He understands Himself quite freely, though necessarily.
Further, this inevitable necessity in things does away neither with divine nor human laws. The principles of morality, whether they receive from God Himself the form of laws or institutions, or whether they do not, are still divine and salutary; whether we receive the good, which flows from virtue and the divine love, as from God in the capacity of a judge, or as from the necessity of the divine nature, it will in either case be equally desirable; on the other hand, the evils following from wicked actions and passions are not less to be feared because they are necessary consequences.[23] Lastly, in our actions, whether they be necessary or contingent, we are led by hope and fear.
Men are only without excuse before God, because they are in God's power, as clay is in the hands of the potter, who from the same lump makes vessels, some to honor, some to dishonor.... [24] When I said in my former letter that we are inexcusable, because we are in the power of God, like clay in the hands of the potter, I meant to be understood in the sense that no one can bring a complaint against God for having given him a weak nature, or infirm spirit. A circle might as well complain to God for not being endowed with the properties of a sphere, or a child who is tortured, say, with stone, for not being given a healthy body, as a man of feeble spirit, because God has denied to him fortitude, and the true knowledge and love of the Deity, or because he is endowed with so weak a nature that he cannot check or moderate his desires. For the nature of each thing is only competent to do that which follows necessarily from its given cause.
That every man cannot be brave, and that we can no more command for ourselves a healthy body than a healthy mind, nobody can deny, without giving the lie to experience, as well as to reason. "But," you urge, "if men sin by nature, they are excusable"; but you do not state the conclusion you draw, whether that God cannot be angry with them, or that they are worthy of blessedness—that is, of the knowledge and love of God. If you say the former, I fully admit that God cannot be angry, and that all things are done in accordance with His will; but I deny that all men ought, therefore, to be blessed—men may be excusable, and nevertheless, be without blessedness and afflicted in many ways.[25] A horse is excusable for being a horse and not a man; but, nevertheless, he must needs be a horse and not a man. He who goes mad from the bite of a dog is excusable, yet he is rightly suffocated. Lastly, he who cannot govern his desires, and keep them in check with the fear of the laws, though his weakness may be excusable, yet he cannot enjoy with contentment, the knowledge and love of God, but necessarily perishes.
FOOTNOTES:
[19] ... I say that a thing is free, which exists and acts solely by the necessity of its own nature. Thus also God understands Himself and all things freely, because it follows solely from the necessity of His nature that He should understand all things. You see I do not place freedom in free decision, but in free necessity. However, let us descend to created things, which are all determined by external causes to exist and operate in a given determinate manner. In order that this may be clearly understood, let us conceive a very simple thing. For instance, a stone receives from the impulsion of an external cause a certain quantity of motion, by virtue of which it continues to move after the impulsion given by the external cause has ceased. The permanence of the stone's motion is constrained, not necessary because it must be defined by the impulsion of an external cause. What is true of the stone is true of an individual, however complicated its nature, or varied its functions, inasmuch as every individual thing is necessarily determined by some external cause to exist and operate in a fixed and determinate manner.
Further conceive, I beg, that a stone, while continuing in motion, should be capable of thinking and knowing, that it is endeavoring, as far as it can, to continue to move. Such a stone, being conscious merely of its own endeavor and not at all indifferent, would believe itself to be completely free, and would think that it continued in motion solely because of its own wish. This is that human freedom, which all boast that they possess, and which consists solely in the fact, that men are conscious of their own desire, but are ignorant of the causes whereby that desire has been determined.[20] ...
