I.6. From everything which is or happens in the world, it is easy to praise Providence, if a man possesses these two qualities, the faculty of seeing what belongs and happens to all persons and things, and a grateful disposition. If he does not possess these two qualities, one man will not see the use of things which are and which happen; another will not be thankful for them, even if he does know them. If God had made colours, but had not made the faculty of seeing them, what would have been their use? None at all. On the other hand, if He had made the faculty of vision, but had not made objects such as to fall under the faculty, what in that case also would have been the use of it? None at all. Well, suppose that He had made both, but had not made light? In that case, also, they would have been of no use. Who is it, then, who has fitted this to that and that to this? And who is it that has fitted the knife to the case and the case to the knife? Is it no one? And, indeed, from the very structure of things which have attained their completion, we are accustomed to show that the work is certainly the act of some artificer, and that it has not been constructed without a purpose. Does then each of these things demonstrate the workman, and do not visible things and the faculty of seeing and light demonstrate Him? And the existence of male and female, and the desire of each for conjunction, and the power of using the parts which are constructed, do not even these declare the workman? If they do not, let us consider the constitution of our understanding according to which, when we meet with sensible objects, we simply receive impressions from them, but we also select something from them, and subtract something, and add, and compound by means of them these things or those, and, in fact, pass from some to other things which, in a manner, resemble them: is not even this sufficient to move some men, and to induce them not to forget the workman? If not so, let them explain to us what it is that makes each several thing, or how it is possible that things so wonderful and like the contrivances of art should exist by chance and from their own proper motion? 

What, then, are these things done in us only. Many, indeed, in us only, of which the rational animal had peculiar need; but you will find many common to us with irrational animals. Do they them understand what is done? By no means. For use is one thing, and understanding is another: God had need of irrational animals to make use of appearances, but of us to understand the use of appearances. It is therefore enough for them to eat and to drink, and to sleep and to copulate, and to do all the other things which they severally do. But for us, to whom He has given also the faculty, these things are not sufficient; for unless we act in a proper and orderly manner, and conformably to the nature and constitution of each thing, we shall never attain our true end. For where the constitutions of living beings are different, there also the acts and the ends are different. In those animals, then, whose constitution is adapted only to use, use alone is enough: but in an animal which has also the power of understanding the use, unless there be the due exercise of the understanding, he will never attain his proper end. Well then God constitutes every animal, one to be eaten, another to serve for agriculture, another to supply cheese, and another for some like use; for which purposes what need is there to understand appearances and to be able to distinguish them? But God has introduced man to be a spectator of God and of His works; and not only a spectator of them, but an interpreter. For this reason it is shameful for man to begin and to end where irrational animals do, but rather he ought to begin where they begin, and to end where nature ends in us; and nature ends in contemplation and understanding, in a way of life conformable to nature. Take care then not to die without having been spectators of these things. . . .

I.14. When a person asked [Epictetus] how a man could be convinced that all his actions are under the inspection of God, he answered, Do you not think that all things are united in one? "I do," the person replied. Well, do you not think that earthly things have a natural agreement and union with heavenly things? "I do." And how else so regularly as if by God's command, when He bids the plants to flower, do they flower? when He bids them to send forth shoots, do they shoot? when He bids them to produce fruit, how else do they produce fruit? when He bids the fruit to ripen, does it ripen? when again He bids them to cast down the fruits, how else do they cast them down? and when to shed the leaves, do they shed the leaves? and when He bids them to fold themselves up and to remain quiet and rest, how else do they remain quiet and rest? And how else at the growth and the wane of the moon, and at the approach and recession of the sun, are so great an alteration and change to the contrary seen in earthly things? But are plants and our bodies so bound up and united with the whole, and are not our souls much more? and our souls so bound up and in contact with God as parts of Him and portions of Him; and does not God perceive every motion of these parts as being His own motion connate with Himself? Now are you able to think of the divine administration, and about all things divine, and at the same time also about human affairs, and to be moved by ten thousand things at the same time in your senses and in your understanding, and to assent to some, and to dissent from others, and again as to some things to suspend your judgment; and do you retain in your soul so many impressions from so many and various things, and being moved by them, do you fall upon notions similar to those first impressed, and do you retain numerous arts and the memories of ten thousand things; and is not God able to oversee all things, and to be present with all, and to receive from all a certain communication? And is the sun able to illuminate so large a part of the All, and to leave so little not illuminated, that part only which is occupied by the earth's shadow; and He who made the sun itself and makes it go round, being a small part of Himself compared with the whole, cannot He perceive all things? 

“But I cannot," the man may reply, "comprehend all these things at once." But who tells you that you have equal power with Zeus? Nevertheless he has placed by every man a guardian, every man's daimon, to whom he has committed the care of the man, a guardian who never sleeps, is never deceived. For to what better and more careful guardian could He have entrusted each of us? When, then, you have shut the doors and made darkness within, remember never to say that you are alone, for you are not; but God is within, and your daimon is within, and what need have they of light to see what you are doing? To this God you ought to swear an oath just as the soldiers do to Caesar. But they who are hired for pay swear to regard the safety of Caesar before all things; and you who have received so many and such great favours, will you not swear, or when you have sworn, will you not abide by your oath? And what shall you swear? Never to be disobedient, never to make any charges, never to find fault with anything that he has given, and never unwillingly to do or to suffer anything, that is necessary. Is this oath like the soldier's oath? The soldiers swear not to prefer any man to Caesar: in this oath men swear to honour themselves before all.

IV.7.   . . . .Then through madness is it possible for a man to be so disposed towards these things, and the Galilaeans through habit,¹ and is it possible that no man can learn from reason and from demonstration that God has made all the things in the universe and the universe itself completely free from hindrance and perfect, and the parts of it for the use of the whole? All other animals indeed are incapable of comprehending the administration of it; but the rational animal man has faculties for the consideration of all these things, and for understanding that it is a part, and what kind of a part it is, and that it is right for the parts to be subordinate to the whole. And besides this being naturally noble, magnanimous and free, man sees that of the things which surround him some are free from hindrance and in his power, and the other things are subject to hindrance and in the power of others; that the things which are free from hindrance are in the power of the will; and those which are subject to hindrance are the things which are not in the power of the will. And for this reason if he thinks that his good and his interest be in these things only which are free from hindrance and in his own power, he will be free, prosperous, happy, free from harm, magnanimous, pious, thankful to God² for all things; in no matter finding fault with any of the things which have not been put in his power, nor blaming any of them.³ But if he thinks that his good and his interest are in externals and in things which are not in the power of his will, he must of necessity be hindered, be impeded, be a slave to those who have the power over the things which he admires (desires) and fears; and he must of necessity be impious because he thinks that he is harmed by God, and he must be unjust because he always claims more than belongs to him; and he must of necessity be abject and mean. . . .
