It is now clear that according to Isidore’s way of thinking, a fact belonging to one set of phenomena might be caused or explained by something totally different in another sphere. This being so, it was inevitable that there should be an effort to pass from the known to the unknown along the path thus suggested. When we reflect that, for the medieval thinker, there were three kinds of knowledge—namely, knowledge of the material, the moral, and the spiritual—and that they were in an ascending scale of value, it will appear equally inevitable that this effort to pass from the known to the unknown should be mainly an effort to pass from the material and obvious to the intangible and unseen, though more real, spiritual world. In this consideration we have the chief explanation of medieval allegory.[98]
In Isidore we find that allegorical interpretation is a thing of little spontaneity. The allegorizing of the Scriptures had long before his time settled down into a system. In his Certain Allegories of the Holy Scriptures a list is given of the most noted mystical interpretations of Scripture, a dry enumeration, with now and then an interesting side-light upon the opinion of the time. The extent to which the Scripture was subject to allegorizing may be guessed from the fact that Isidore specifies that “the ten commandments must be taken literally”.[99] Allegory is applied also to the phenomena of nature. In De Natura Rerum Isidore makes a regular practice of first giving the explanation of natural phenomena and following this with the “higher meaning”. Thus the sun has Christ for its allegorical meaning; the stars, the saints; thunder is “the rebuke from on high of the divine voice”, or it may be “the loud preaching of the saints, which dins with loud clamor in the ears of the faithful over all the circle of the lands”.[100] In the Etymologies this “higher meaning” of natural objects is rarely given.
The view held in the dark ages of the natural and the supernatural and of their relative proportions in the outlook on life, was precisely the reverse of that held by intelligent men in modern times. For us the material universe has taken on the aspect of order; within its limits phenomena seem to follow definite modes of behavior, upon the evidence of which a body of scientific knowledge has been built up. Indeed at times in certain branches of science there has been danger of a dogmatism akin to, if the reverse of, that which prevailed in medieval times with reference to the supernatural. On the other hand, the certainty that once existed in regard to the supernatural world has faded away; no means of investigating it that commands confidence has been devised, and any idea held in regard to it is believed to be void of truth if inconsistent with the conclusions reached by science. In all these respects the attitude of Isidore and his time is exactly opposite to ours. To him the supernatural world was the demonstrable and ordered one. Its phenomena, or what were supposed to be such, were accepted as valid, while no importance was attached to evidence offered by the senses as to the material. It may even be said that the supernatural universe bulked far larger in the mind of the medieval thinker than does the natural in that of the modern, and it was fortified by an immeasurably stronger and more uncritical dogmatism.
It is evident, therefore, that if we compare the dogmatic world-view of the medieval thinker with the more tentative one of the modern scientist, allowance must be made for the fact that they take hold of the universe at opposite ends. Their plans are so fundamentally different that it is hard to express the meaning of one in terms of the other.
Isidore’s method of apprehending the supernatural world can hardly be called mysticism. With mysticism we associate intuition and exalted feeling, and the examples that have been given of Isidore’s thinking in terms of allegory and number, show that he thought of the supernatural in the same prosaic and literal way as he did of the natural; there was no break for him between them, nor was there any change of intellectual atmosphere when he crossed the line. So the higher sense at least of the term ‘mystic’ must be denied him. His share in the mysticism of his age, which he accepted unquestioningly, was not a positive one; he exhibits rather the negative side of mysticism, the intellectual haziness, slothfulness and self-delusion by which it was so often accompanied in medieval times.
Isidore believed that in point of time the supernatural preceded the natural. He says that God “created all things out of nothing”,[101] and, again, that “the matter from which the universe was formed preceded the things created out of it not in time, but in origin, in the same sense as sound precedes music”.[102] It is evident that he regarded the material as an emanation from the spiritual. With such an origin the material world was naturally subservient to spiritual control, and miracles caused little wonder. They “are not contrary to nature, because they are caused by the divine will, and the will of the Creator is the nature of each created thing.... A miracle, therefore, does not happen contrary to nature, but contrary to nature as known.”[103] The supernatural thus not only preceded, but dominated, the natural. Finally, the universe was to disappear at the end of six ages, and all was to be reabsorbed in the supernatural. The world of nature, then, was merely a passing incident in a greater reality that contained it.
As in the universe at large, so in man the supernatural completely overshadows the natural. The soul is all-important and theory in regard to it is precise and dogmatic. “As to the soul,” Isidore says, “the philosophers of this world have described with great uncertainty what it is, what it is like, where it is, what form it has, and what its power is. Some have said it is fire; others, blood; others that it is incorporeal and has no shape. A number have believed with rash impiety that it is a part of the divine nature. But we say that it is not fire nor blood, but that it is incorporeal, capable of feeling and of change; without weight, shape, or color. And we say that the soul is not a part, but a creature of God, and that it is not of the substance of God, or of any underlying matter of the elements, but was created out of nothing.”[104] He says further, that the soul “has a beginning but cannot have an end”.[105] All the activities by which life is manifested are considered as parts or functions of the soul. Dum contemplatur, spiritus est; dum sentit, sensus est; dum sapit, animus est; dum intelligit, mens est; dum discernit, ratio est; dum consentit, voluntas est; dum recordatur, memoria est; et dum membra vegetat, anima est.[106]
In contrast with the soul the body scarcely deserves to be spoken of except with disparagement. Its goods are to be unhesitatingly sacrificed to those of the supernatural element in man, or rather, they are not regarded as goods at all. “It is advantageous,” Isidore says, “for those who are well and strong to become infirm, lest through the vigor of their health they be defiled by illicit passions and the desire for luxury”.[107] The present life of the body has no value; it is brief and wretched. “Holy men desire to spurn the world and devote the activity of their minds to things above, in order to convey themselves back to the place from which they have come, and withdraw from the place into which they have been cast.”[108] Thus philosophy of the supernatural culminated in asceticism.
Isidore’s supernatural world has its inhabitants, and in dealing with these he has a theology, an angelology, and a demonology; in all of which fields his ideas are more precise and clear-cut than where he speaks of the material world.
His theology is of little interest; it consists in the orthodox view of the time, accepted without a shadow of criticism. He says, “We are not permitted to form any belief of our own will, or to choose a belief that someone else has accepted of his own. We have God’s apostles as authorities, who did not themselves choose anything of what they should believe, but they faithfully transmitted to the nations the teaching received from Christ. And so even if an angel from heaven shall preach otherwise, let him be anathema”.[109]
