to Objection 1: There is a difference between universal and particular causes. A thing can escape the order of a particular cause; but not the order of a universal cause. For nothing escapes the order of a particular cause, except through the intervention and hindrance of some other particular cause; as, for instance, wood may be prevented from burning, by the action of water. Since then, all particular causes are included under the universal cause, it could not be that any effect should take place outside the range of that universal cause. So far then as an effect escapes the order of a particular cause, it is said to be casual or fortuitous in respect to that cause; but if we regard the universal cause, outside whose range no effect can happen, it is said to be foreseen. Thus, for instance, the meeting of two servants, although to them it appears a chance circumstance, has been fully foreseen by their master, who has purposely sent to meet at the one place, in such a way that the one knows not about the other.
Reply to Objection 2: It is otherwise with one who has care of a particular thing, and one whose providence is universal, because a particular provider excludes all defects from what is subject to his care as far as he can; whereas, one who provides universally allows some little defect to remain, lest the good of the whole should be hindered. Hence, corruption and defects in natural things are said to be contrary to some particular nature; yet they are in keeping with the plan of universal nature; inasmuch as the defect in one thing yields to the good of another, or even to the universal good: for the corruption of one is the generation of another, and through this it is that a species is kept in existence. Since God, then, provides universally for all being, it belongs to His providence to permit certain defects in particular effects, that the perfect good of the universe may not be hindered, for if all evil were prevented, much good would be absent from the universe. A lion would cease to live, if there were no slaying of animals; and there would be no patience of martyrs if there were no tyrannical persecution. Thus Augustine says (Enchiridion 2): "Almighty God would in no wise permit evil to exist in His works, unless He were so almighty and so good as to produce good even from evil." It would appear that it was on account of these two arguments to which we have just replied, that some were persuaded to consider corruptible things---e.g. casual and evil things---as removed from the care of divine providence.
Reply to Objection 3: Man is not the author of nature; but he uses natural things in applying art and virtue to his own use. Hence human providence does not reach to that which takes place in nature from necessity; but divine providence extends thus far, since God is the author of nature. Apparently it was this argument that moved those who withdrew the course of nature from the care of divine providence, attributing it rather to the necessity of matter, as Democritus, and others of the ancients.
Reply to Objection 4: When it is said that God left man to himself, this does not mean that man is exempt from divine providence; but merely that he has not a prefixed operating force determined to only the one effect; as in the case of natural things, which are only acted upon as though directed by another towards an end; and do not act of themselves, as if they directed themselves towards an end, like rational creatures, through the possession of free will, by which these are able to take counsel and make a choice. Hence it is significantly said: "In the hand of his own counsel." But since the very act of free will is traced to God as to a cause, it necessarily follows that everything happening from the exercise of free will must be subject to divine providence. For human providence is included under the providence of God, as a particular under a universal cause. God, however, extends His providence over the just in a certain more excellent way than over the wicked; inasmuch as He prevents anything happening which would impede their final salvation. For "to them that love God, all things work together unto good" (Rm. 8:28). But from the fact that He does not restrain the wicked from the evil of sin, He is said to abandon them: not that He altogether withdraws His providence from them; otherwise they would return to nothing, if they were not preserved in existence by His providence. This was the reason that had weight with Tully, who withdrew from the care of divine providence human affairs concerning which we take counsel.
Reply to Objection 5: Since a rational creature has, through its free will, control over its actions, as was said above ( Question [19], Article [10]), it is subject to divine providence in an especial manner, so that something is imputed to it as a fault, or as a merit; and there is given it accordingly something by way of punishment or reward. In this way, the Apostle withdraws oxen from the care of God: not, however, that individual irrational creatures escape the care of divine providence; as was the opinion of the Rabbi Moses.
Whether God has immediate providence over everything?
Objection 1: It seems that God has not immediate providence over all things. For whatever is contained in the notion of dignity, must be attributed to God. But it belongs to the dignity of a king, that he should have ministers; through whose mediation he provides for his subjects. Therefore much less has God Himself immediate providence over all things.
Objection 2: Further, it belongs to providence to order all things to an end. Now the end of everything is its perfection and its good. But it appertains to every cause to direct its effect to good; wherefore every active cause is a cause of the effect of providence. If therefore God were to have immediate providence over all things, all secondary causes would be withdrawn.
Objection 3: Further, Augustine says (Enchiridion 17) that, "It is better to be ignorant of some things than to know them, for example, vile things": and the Philosopher says the same (Metaph. xii, 51). But whatever is better must be assigned to God. Therefore He has not immediate providence over bad and vile things.
On the contrary, It is said (Job 34:13): "What other hath He appointed over the earth? or whom hath He set over the world which He made?" On which passage Gregory says (Moral. xxiv, 20): "Himself He ruleth the world which He Himself hath made."
I answer that, Two things belong to providence---namely, the type of the order of things foreordained towards an end; and the execution of this order, which is called government. As regards the first of these, God has immediate providence over everything, because He has in His intellect the types of everything, even the smallest; and whatsoever causes He assigns to certain effects, He gives them the power to produce those effects. Whence it must be that He has beforehand the type of those effects in His mind. As to the second, there are certain intermediaries of God's providence; for He governs things inferior by superior, not on account of any defect in His power, but by reason of the abundance of His goodness; so that the dignity of causality is imparted even to creatures. Thus Plato's opinion, as narrated by Gregory of Nyssa (De Provid. viii, 3), is exploded. He taught a threefold providence. First, one which belongs to the supreme Deity, Who first and foremost has provision over spiritual things, and thus over the whole world as regards genus, species, and universal causes. The second providence, which is over the individuals of all that can be generated and corrupted, he attributed to the divinities who circulate in the heavens; that is, certain separate substances, which move corporeal things in a circular direction. The third providence, over human affairs, he assigned to demons, whom the Platonic philosophers placed between us and the gods, as Augustine tells us (De Civ. Dei, 1, 2: viii, 14).
Reply to Objection 1: It pertains to a king's dignity to have ministers who execute his providence. But the fact that he has not the plan of those things which are done by them arises from a deficiency in himself. For every operative science is the more perfect, the more it considers the particular things with which its action is concerned.
Reply to Objection 2: God's immediate provision over everything does not exclude the action of secondary causes; which are the executors of His order, as was said above
