Discourses: Book 1 14 : 1

Now when someone asked him how a man could be convinced that each thing which he does is under the eye of God, Do you not think, he answered, that all things are united in one?—I do, said the other.—Very well, do you not think that what is on earth feels the influence of that which is in heaven?—I do, he replied.—For how else comes it that so regularly, as if from God's command, when He bids the plants flower, they flower, when He bids them put forth shoots, they put them forth, when He bids them bear their fruit, they bear it, when to ripen, they ripen; when again He bids them drop their fruit and let fall their leaves and gather themselves together and remain quiet and take their rest, they remain quiet and take their rest? And how else comes it that at the waxing and waning of the moon and at the approach and recession of the sun we see among the things that are on earth so great an alteration and change to the opposite? But are the plants and our own bodies so closely bound up with the universe, and do they so intimately share its affections, and is not the same much more true of our own souls? But if our souls are so bound up with God and joined together with Him, as being parts and portions of His being, does not God perceive their every motion as being a motion of that which is His own and of one body with Himself? And yet you have power to think about the divine dispensation and about each several item among things divine, and at the same time also about human affairs, and you have the faculty of being moved by myriads of matters at the same time both in your senses and in your intelligence, and at the same time you assent to some, while you dissent from others, or suspend judgement about them; and you guard in your own soul so many impressions derived from so many and various matters, and, on being moved by these impressions, your mind falls upon notions corresponding to the impressions first made, and so from myriads of matters you derive and retain arts, one after the other, and memories. All this you do, and is God not able to oversee all things and to be present with all and to have a certain communication from them all? Yet the sun is capable of illuminating so large a portion of the universe, and of leaving unilluminated only the small space which is no larger than can be covered by the shadow that the earth casts; and is He who has created the sun, which is but a small portion of Himself in comparison with the whole, and causes it to revolve, is He not able to perceive all things?
