Against the Heathen

³⁰ The soul of man, being intellectual, can know God of itself, if it be true to its own nature.

The tenets we have been speaking of have been proved to be nothing more than a false guide for life; but the way of truth will aim at reaching the real and true God. But for its knowledge and accurate comprehension, there is need of none other save of ourselves. Neither as God Himself is above all, is the road to Him afar off or outside ourselves, but it is in us and it is possible to find it from ourselves, in the first instance, as Moses also taught, when he said: “The word” of faith “is within your heart.” Which very thing the Saviour declared and confirmed, when He said: “The kingdom of God is within you.” 2. For having in ourselves faith, and the kingdom of God, we shall be able quickly to see and perceive the King of the Universe, the saving Word of the Father. And let not the Greeks, who worship idols, make excuses, nor let any one else simply deceive himself, professing to have no such road and therefore finding a pretext for his godlessness. 3. For we all have set foot upon it, and have it, even if not all are willing to travel by it, but rather to swerve from it and go wrong, because of the pleasures of life which attract them from without. And if one were to ask, what road is this? I say that it is the soul of each one of us, and the intelligence which resides there. For by it alone can God be contemplated and perceived. 4. Unless, as they have denied God, the impious men will repudiate having a soul; which indeed is more plausible than the rest of what they say, for it is unlike men possessed of an intellect to deny God, its Maker and Artificer. It is necessary then, for the sake of the simple, to show briefly that each one of mankind has a soul, and that soul rational; especially as certain of the sectaries deny this also, thinking that man is nothing more than the visible form of the body. This point once proved, they will be furnished in their own persons with a clearer proof against the idols.

31. Proof of the existence of the rational soul. (1) Difference of man from the brutes. (2) Man's power of objective thought. Thought is to sense as the musician to his instrument. The phenomena of dreams bear this out.

Firstly, then, the rational nature of the soul is strongly confirmed by its difference from irrational creatures. For this is why common use gives them that name, because, namely, the race of mankind is rational. 2. Secondly, it is no ordinary proof, that man alone thinks of things external to himself, and reasons about things not actually present, and exercises reflection, and chooses by judgment the better of alternative reasonings. For the irrational animals see only what is present, and are impelled solely by what meets their eye, even if the consequences to them are injurious, while man is not impelled toward what he sees merely, but judges by thought what he sees with his eyes. Often for example his impulses are mastered by reasoning; and his reasoning is subject to after-reflection. And every one, if he be a friend of truth, perceives that the intelligence of mankind is distinct from the bodily senses. 3. Hence, because it is distinct, it acts as judge of the senses, and while they apprehend their objects, the intelligence distinguishes, recollects, and shows them what is best. For the sole function of the eye is to see, of the ears to hear, of the mouth to taste, of the nostrils to apprehend smells, and of the hands to touch. But what one ought to see and hear, what one ought to touch, taste and smell, is a question beyond the senses, and belonging to the soul and to the intelligence which resides in it. Why, the hand is able to take hold of a sword-blade, and the mouth to taste poison, but neither knows that these are injurious, unless the intellect decide. 4. And the case, to look at it by aid of a simile, is like that of a well-fashioned lyre in the hands of a skilled musician. For as the strings of the lyre have each its proper note, high, low, or intermediate, sharp or otherwise, yet their scale is indistinguishable and their time not to be recognized, without the artist. For then only is the scale manifest and the time right, when he that is holding the lyre strikes the strings and touches each in tune. In like manner, the senses being disposed in the body like a lyre, when the skilled intelligence presides over them, then too the soul distinguishes and knows what it is doing and how it is acting. 5. But this alone is peculiar to mankind, and this is what is rational in the soul of mankind, by means of which it differs from the brutes, and shows that it is truly distinct from what is to be seen in the body. Often, for example, when the body is lying on the earth, man imagines and contemplates what is in the heavens. Often when the body is quiet, and at rest and asleep, man moves inwardly, and beholds what is outside himself, travelling to other countries, walking about, meeting his acquaintances, and often by these means divining and forecasting the actions of the day. But to what can this be due save to the rational soul, in which man thinks of and perceives things beyond himself?

32. (3) The body cannot originate such phenomena; and in fact the action of the rational soul is seen in its over-ruling the instincts of the bodily organs.

We add a further point to complete our demonstration for the benefit of those who shamelessly take refuge in denial of reason. How is it, that whereas the body is mortal by nature, man reasons on the things of immortality, and often, where virtue demands it, courts death? Or how, since the body lasts but for a time, does man imagine of things eternal, so as to despise what lies before him, and desire what is beyond? The body could not have spontaneously such thoughts about itself, nor could it think upon what is external to itself. For it is mortal and lasts but for a time. And it follows that that which thinks what is opposed to the body and against its nature must be distinct in kind. What then can this be, save a rational and immortal soul? For it introduces the echo of higher things, not outside, but within the body, as the musician does in his lyre. 2. Or how again, the eye being naturally constituted to see and the ear to hear, do they turn from some objects and choose others? For who is it that turns away the eye from seeing? Or who shuts off the ear from hearing, its natural function? Or who often hinders the palate, to which it is natural to taste things, from its natural impulse? Or who withholds the hand from its natural activity of touching something, or turns aside the sense of smell from its normal exercise? Who is it that thus acts against the natural instincts of the body? Or how does the body, turned from its natural course, turn to the counsels of another and suffer itself to be guided at the beck of that other? Why, these things prove simply this, that the rational soul presides over the body. 3. For the body is not even constituted to drive itself, but it is carried at the will of another, just as a horse does not yoke himself, but is driven by his master. Hence laws for human beings to practise what is good and to abstain from evil-doing, while to the brutes evil remains unthought of and undiscerned, because they lie outside rationality and the process of understanding. I think then that the existence of a rational soul in man is proved by what we have said.

33. The soul immortal. Proved by (1) its being distinct from the body, (2) its being the source of motion, (3) its power to go beyond the body in imagination and thought.
