XXI. It is true, I might expatiate, did the subject require it, on the many and various objects with which the soul will be entertained in those heavenly regions; when I reflect on which, I am apt to wonder at the boldness of some philosophers, who are so struck with admiration at the knowledge of nature as to thank, in an exulting manner, the first inventor and teacher of natural philosophy, and to reverence him as a God; for they declare that they have been delivered by his means from the greatest tyrants, a perpetual terror, and a fear that molested them by night and day. What is this dread--this fear? What old woman is there so weak as to fear these things, which you, forsooth, had you not been acquainted with natural philosophy, would stand in awe of?
The hallow'd roofs of Acheron, the dread Of Orcus, the pale regions of the dead.
And does it become a philosopher to boast that he is not afraid of these things, and that he has discovered them to be false? And from this we may perceive how acute these men were by nature, who, if they had been left without any instruction, would have believed in these things. But now they have certainly made a very fine acquisition in learning that when the day of their death arrives, they will perish entirely. And if that really is the case--for I say nothing either way--what is there agreeable or glorious in it? Not that I see any reason why the opinion of Pythagoras and Plato may not be true; but even although Plato were to have assigned no reason for his opinion (observe how much I esteem the man), the weight of his authority would have borne me down; but he has brought so many reasons, that he appears to me to have endeavored to convince others, and certainly to have convinced himself.
XXII. But there are many who labor on the other side of the question, and condemn souls to death, as if they were criminals capitally convicted; nor have they any other reason to allege why the immortality of the soul appears to them to be incredible, except that they are not able to conceive what sort of thing the soul can be when disentangled from the body; just as if they could really form a correct idea as to what sort of thing it is, even when it is in the body; what its form, and size, and abode are; so that were they able to have a full view of all that is now hidden from them in a living body, they have no idea whether the soul would be discernible by them, or whether it is of so fine a texture that it would escape their sight. Let those consider this, who say that they are unable to form any idea of the soul without the body, and then they will see whether they can form any adequate idea of what it is when it is in the body. For my own part, when I reflect on the nature of the soul, it appears to me a far more perplexing and obscure question to determine what is its character while it is in the body--a place which, as it were, does not belong to it--than to imagine what it is when it leaves it, and has arrived at the free æther, which is, if I may so say, its proper, its own habitation. For unless we are to say that we cannot apprehend the character or nature of anything which we have never seen, we certainly may be able to form some notion of God, and of the divine soul when released from the body. Dicæarchus, indeed, and Aristoxenus, because it was hard to understand the existence and substance and nature of the soul, asserted that there was no such thing as a soul at all. It is, indeed, the most difficult thing imaginable to discern the soul by the soul. And this, doubtless, is the meaning of the precept of Apollo, which advises every one to know himself. For I do not apprehend the meaning of the God to have been that we should understand our members, our stature, and form; for we are not merely bodies; nor, when I say these things to you, am I addressing myself to your body: when, therefore, he says, "Know yourself," he says this, "Inform yourself of the nature of your soul;" for the body is but a kind of vessel, or receptacle of the soul, and whatever your soul does is your own act. To know the soul, then, unless it had been divine, would not have been a precept of such excellent wisdom as to be attributed to a God; but even though the soul should not know of what nature itself is, will you say that it does not even perceive that it exists at all, or that it has motion? On which is founded that reason of Plato's, which is explained by Socrates in the Phædrus, and inserted by me, in my sixth book of the Republic.
