Thomas Aquinas

“ 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. ”

“ It is better for us not to know low and vile things, because by them we are impeded in our knowledge of what is better and higher; for we cannot understand many things simultaneously; because the thought of evil sometimes perverts the will towards evil. This does not hold with God, Who sees everything simultaneously at one glance, and whose will cannot turn in the direction of evil.
Art. 4 - Whether providence imposes any necessity on things foreseen? ”

“ 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. ”

“ We must say, however, that all things are subject to divine providence, not only in general, but even in their own individual selves. This is mad evident thus. For since every agent acts for an end, the ordering of effects towards that end extends as far as the causality of the first agent extends. Whence it happens that in the effects of an agent something takes place which has no reference towards the end, because the effect comes from a cause other than, and outside the intention of the agent. ”

“ 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. ”

“ It seems that divine providence imposes necessity upon things foreseen. For every effect that has a "per se" cause, either present or past, which it necessarily follows, happens from necessity; as the Philosopher proves (Metaph. vi, 7) . But the providence of God, since it is eternal, pre-exists; and the effect flows from it of necessity, for divine providence cannot be frustrated. Therefore divine providence imposes a necessity upon things foreseen.
Objection 2: Further, every provider makes his work as stable as he can, lest it should fail. But God is most powerful. ”

“ 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. ”

“ But the causality of God, Who is the first agent, extends to all being, not only as to constituent principles of species, but also as to the individualizing principles; not only of things incorruptible, but also of things corruptible. Hence all things that exist in whatsoever manner are necessarily directed by God towards some end ”

“ Further, whatever happens of necessity does not require providence or prudence. Hence, according to the Philosopher (Ethic. vi, 5,9, 10,11) : "Prudence is the right reason of things contingent concerning which there is counsel and choice." Since, then, many things happen from necessity, everything cannot be subject to providence.
Objection 4: Further, whatsoever is left to itself cannot be subject to the providence of a governor. But men are left to themselves by God in accordance with the words: "God made man from the beginning, and left him in the hand of his own counsel" (Ecclus. 15:14) . ”

“ 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 ”

“ 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 ”

“ 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 ”

“ 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. ”

“ Rabbi Moses, however, excluded men from the generality of things corruptible, on account of the excellence of the intellect which they possess, but in reference to all else that suffers corruption he adhered to the opinion of the others. ”
