The Stromata, or Miscellanies

And mutual and reciprocal causes are predicated, some of the same things, as the merchant and the retailer are causes of gain; and sometimes one of one thing and others of another, as the sword and the flesh; for the one is the cause to the flesh of being cut, and the flesh to the sword of cutting. [It is well said,] “An eye for an eye, life for life.” For he who has wounded another mortally, is the cause to him of death, or of the occurrence of death. But on being mortally wounded by him in turn, he has had him as a cause in turn, not in respect of being a cause to him, but in another respect. For he becomes the cause of death to him, not that it was death returned the mortal stroke, but the wounded man himself. So that he was the cause of one thing, and had another cause. And he who has done wrong becomes the cause to another, to him who has been wronged. But the law which enjoins punishment to be inflicted is the cause not of injury, but to the one of retribution, to the other of discipline. So that the things which are causes, are not causes to each other as causes.

It is still asked, if many things in conjunction become many causes of one thing. For the men who pull together are the causes of the ship being drawn down; but along with others, unless what is a joint cause be a cause.

Others say, if there are many causes, each by itself becomes the cause of one thing. For instance, the virtues, which are many, are causes of happiness, which is one; and of warmth and pain, similarly, the causes are many. Are not, then, the many virtues one in power, and the sources of warmth and of pain so, also? And does not the multitude of the virtues, being one in kind, become the cause of the one result, happiness?

But, in truth, Procatarctic causes are more than one both generically and specifically; as, for example, cold, weakness, fatigue, dyspepsia, drunkenness, generically, of any disease; and specifically, of fever. But Synectic causes are so, generically alone, and not also specifically.

For of pleasant odour, which is one thing genetically, there are many specific causes, as frankincense, rose, crocus, styrax, myrrh, ointment. For the rose has not the same kind of sweet fragrance as myrrh.

And the same thing becomes the cause of contrary effects; sometimes through the magnitude of the cause and its power, and sometimes in consequence of the susceptibility of that on which it acts. According to the nature of the force, the same string, according to its tension or relaxation, gives a shrill or deep sound. And honey is sweet to those who are well, and bitter to those who are in fever, according to the state of susceptibility of those who are affected. And one and the same wine inclines some to rage, and others to merriment. And the same sun melts wax and hardens clay.

Further, of causes, some are apparent; others are grasped by a process of reasoning; others are occult; others are inferred analogically.

And of causes that are occult, some are occult temporarily, being hidden at one time, and at another again seen clearly; and some are occult by nature, and capable of becoming at no time visible. And of those who are so by nature, some are capable of being apprehended; and these some would not call occult, being apprehended by analogy, through the medium of signs, as, for example, the symmetry of the passages of the senses, which are contemplated by reason. And some are not capable of being apprehended; which cannot in any mode fall under apprehension; which are by their very definition occult.

Now some are Procatarctic, some Synectic, some Joint-causes, some Co-operating causes. And there are some according to nature, some beyond nature. And there are some of disease and by accident, some of sensations, some of the greatness of these, some of times and of seasons.

Procatarctic causes being removed, the effect remains. But a Synectic cause is that, which being present, the effect remains, and being removed, the effect is removed.

The Synectic is also called by the synonymous expression “perfect in itself.” Since it is of itself sufficient to produce the effect.

And if the cause manifests an operation sufficient in itself, the co-operating cause indicates assistance and service along with the other. If, accordingly, it effects nothing, it will not be called even a co-operating cause; and if it does effect something, it is wholly the cause of this, that is, of what is produced by it. That is, then, a co-operating cause, which being present, the effect was produced— the visible visibly, and the occult invisibly.

The Joint-cause belongs also to the genus of causes, as a fellow-soldier is a soldier, and as a fellow-youth is a youth.

The Co-operating cause further aids the Synectic, in the way of intensifying what is produced by it. But the Joint-cause does not fall under the same notion. For a thing may be a Joint-cause, though it be not a Synectic cause. For the Joint-cause is conceived in conjunction with another, which is not capable of producing the effect by itself, being a cause along with a cause. And the Co-operating cause differs from the Joint-cause in this particular, that the Joint-cause produces the effect in that which by itself does not act. But the Co-operating cause, while effecting nothing by itself, yet by its accession to that which acts by itself, co-operates with it, in order to the production of the effect in the intensest degree. But especially is that which becomes co-operating from being Procatarctic, effective in intensifying the force of the cause.
