§46ΤΙ. καταλειφθεισῶν δέ τινων κινήσεων μειζόνων, οἷαι καὶ ἐν οἵοις ἂν τόποις λείπωνται, τοιαῦτα καὶ τοσαῦτα παρέσχοντο ἀφομοιωθέντα ἐντὸς ἔξω τε ἐγερθεῖσιν ἀπομνημονευόμενα φαντάσματα.
When some greater motions are left behind, according to what kind they are and in what places they are left, they present such and so many images, fashioned within to resemble things, which are remembered by those who have awakened to the outside world.
τὸ δὲ περὶ τὴν τῶν κατόπτρων εἰδωλοποιίαν καὶ πάντα ὅσα ἐμφανῆ καὶ λεῖα, κατιδεῖν οὐδὲν ἔτι χαλεπόν.
And as for the image-making of mirrors and of all things that are visible and smooth, it is no longer difficult to understand.
ἐκ γὰρ τῆς ἐντὸς ἐκτός τε τοῦ πυρὸς ἑκατέρου κοινωνίας ἀλλήλοις, ἑνός τε αὖ περὶ τὴν λειότητα ἑκάστοτε γενομένου καὶ πολλαχῇ μεταρρυθμισθέντος, πάντα τὰ τοιαῦτα ἐξ ἀνάγκης ἐμφαίνεται, τοῦ περὶ τὸ πρόσωπον πυρὸς τῷ περὶ τὴν ὄψιν πυρὶ περὶ τὸ λεῖον καὶ λαμπρὸν συμπαγοῦς γιγνομένου.
For from the mutual communion of both fires with each other, the internal and the external, and furthermore, from one fire being formed on each occasion around the smooth surface and being reshaped in many ways, all such things are of necessity reflected, when the fire around the face becomes coalescent with the fire of vision around the smooth and bright surface.
δεξιὰ δὲ φαντάζεται τὰ ἀριστερά, ὅτι τοῖς ἐναντίοις μέρεσιν τῆς ὄψεως περὶ τἀναντία μέρη γίγνεται ἐπαφὴ παρὰ τὸ καθεστὸς ἔθος τῆς προσβολῆς· δεξιὰ δὲ τὰ δεξιὰ καὶ τὰ ἀριστερὰ ἀριστερὰ τοὐναντίον, ὅταν μεταπέσῃ συμπηγνύμενον ᾧ συμπήγνυται φῶς, τοῦτο δέ, ὅταν ἡ τῶν κατόπτρων λειότης, ἔνθεν καὶ ἔνθεν ὕψη λαβοῦσα, τὸ δεξιὸν εἰς τὸ ἀριστερὸν μέρος ἀπώσῃ τῆς ὄψεως καὶ θάτερον ἐπὶ θάτερον.
And the left side appears as the right, because a contact takes place with the opposite parts of the vision around the opposite parts, contrary to the established habit of collision; but on the other hand, the right side appears as the right and the left as the left, when the light which is being coalesced changes its position in relation to that with which it is coalesced, and this happens when the smoothness of the mirrors, receiving heights on this side and on that, repels the right part of the vision to the left part, and the other to the other.
κατὰ δὲ τὸ μῆκος στραφὲν τοῦ προσώπου ταὐτὸν τοῦτο ὕπτιον ἐποίησεν πᾶν φαίνεσθαι, τὸ κάτω πρὸς τὸ ἄνω τῆς αὐγῆς τό τʼ ἄνω πρὸς τὸ κάτω πάλιν ἀπῶσαν.
And when turned along the length of the face, this same thing makes everything appear upside down, repelling the lower part of the light to the upper, and the upper part again to the lower.
ταῦτʼ οὖν πάντα ἔστιν τῶν συναιτίων οἷς θεὸς ὑπηρετοῦσιν χρῆται τὴν τοῦ ἀρίστου κατὰ τὸ δυνατὸν ἰδέαν ἀποτελῶν· δοξάζεται δὲ ὑπὸ τῶν πλείστων οὐ συναίτια ἀλλὰ αἴτια εἶναι τῶν πάντων, ψύχοντα καὶ θερμαίνοντα πηγνύντα τε καὶ διαχέοντα καὶ ὅσα τοιαῦτα ἀπεργαζόμενα.
Now all these are among the cooperative causes which God uses as ministers in bringing to completion the idea of the best so far as is possible; but they are thought by most people to be not cooperative causes but the causes of all things, by cooling and heating, and compacting and dispersing, and producing all such effects.
λόγον δὲ οὐδένα οὐδὲ νοῦν εἰς οὐδὲν δυνατὰ ἔχειν ἐστίν.
But they are incapable of possessing any reason or mind for any purpose.
τῶν γὰρ ὄντων ᾧ νοῦν μόνῳ κτᾶσθαι προσήκει, λεκτέον ψυχήν—τοῦτο δὲ ἀόρατον, πῦρ δὲ καὶ ὕδωρ καὶ γῆ καὶ ἀὴρ σώματα πάντα ὁρατὰ γέγονεν—τὸν δὲ νοῦ καὶ ἐπιστήμης ἐραστὴν ἀνάγκη τὰς τῆς ἔμφρονος φύσεως αἰτίας πρώτας μεταδιώκειν, ὅσαι δὲ ὑπʼ ἄλλων μὲν κινουμένων, ἕτερα δὲ κατὰ ἀνάγκης κινούντων γίγνονται, δευτέρας.
For of existing things, we must say that the only one to which it belongs to acquire mind is the soul—and this is invisible, whereas fire and water and earth and air have all become visible bodies—and the lover of mind and knowledge must of necessity pursue first the causes of the intelligent nature, and secondly those which come to be by things that are moved by others and of necessity move other things.
ποιητέον δὴ κατὰ ταῦτα καὶ ἡμῖν· λεκτέα μὲν ἀμφότερα τὰ τῶν αἰτιῶν γένη, χωρὶς δὲ ὅσαι μετὰ νοῦ καλῶν καὶ ἀγαθῶν δημιουργοὶ καὶ ὅσαι μονωθεῖσαι φρονήσεως τὸ τυχὸν ἄτακτον ἑκάστοτε ἐξεργάζονται.
This indeed we also must do; we must speak of both classes of causes, but separately of those which with mind are craftsmen of things beautiful and good, and of those which, being destitute of wisdom, produce on each occasion a chance, disorderly effect.
§47ΤΙ. τὰ μὲν οὖν τῶν ὀμμάτων συμμεταίτια πρὸς τὸ σχεῖν τὴν δύναμιν ἣν νῦν εἴληχεν εἰρήσθω· τὸ δὲ μέγιστον αὐτῶν εἰς ὠφελίαν ἔργον, διʼ ὃ θεὸς αὔθʼ ἡμῖν δεδώρηται, μετὰ τοῦτο ῥητέον.
Now let the cooperative causes of the eyes for having the power which they have now received be spoken of; but their greatest work for our benefit, for which God has gifted them to us, must be spoken of next.
ὄψις δὴ κατὰ τὸν ἐμὸν λόγον αἰτία τῆς μεγίστης ὠφελίας γέγονεν ἡμῖν, ὅτι τῶν νῦν λόγων περὶ τοῦ παντὸς λεγομένων οὐδεὶς ἄν ποτε ἐρρήθη μήτε ἄστρα μήτε ἥλιον μήτε οὐρανὸν ἰδόντων.
Vision, indeed, in my opinion, has become the cause of the greatest benefit to us, since of the arguments now being spoken concerning the universe, not one would ever have been spoken if we had seen neither stars, nor sun, nor heaven.
νῦν δʼ ἡμέρα τε καὶ νὺξ ὀφθεῖσαι μῆνές τε καὶ ἐνιαυτῶν περίοδοι καὶ ἰσημερίαι καὶ τροπαὶ μεμηχάνηνται μὲν ἀριθμόν, χρόνου δὲ ἔννοιαν περί τε τῆς τοῦ παντὸς φύσεως ζήτησιν ἔδοσαν· ἐξ ὧν ἐπορισάμεθα φιλοσοφίας γένος, οὗ μεῖζον ἀγαθὸν οὔτʼ ἦλθεν οὔτε ἥξει ποτὲ τῷ θνητῷ γένει δωρηθὲν ἐκ θεῶν.
But now, the sight of day and night, months and the revolutions of years, equinoxes and solstices, have created number, and have given us the conception of time and the inquiry into the nature of the universe; from which we have provided ourselves with the class of philosophy, than which no greater good has ever come nor will ever come as a gift from the gods to the mortal race.
λέγω δὴ τοῦτο ὀμμάτων μέγιστον ἀγαθόν· τἆλλα δὲ ὅσα ἐλάττω τί ἂν ὑμνοῖμεν, ὧν ὁ μὴ φιλόσοφος τυφλωθεὶς ὀδυρόμενος ἂν θρηνοῖ μάτην;
I say indeed this is the greatest good of the eyes; but as for the other lesser goods, why should we hymn them, which he who is not a philosopher, if made blind, would lament and bewail in vain?
ἀλλὰ τούτου λεγέσθω παρʼ ἡμῶν αὕτη ἐπὶ ταῦτα αἰτία, θεὸν ἡμῖν ἀνευρεῖν δωρήσασθαί τε ὄψιν, ἵνα τὰς ἐν οὐρανῷ τοῦ νοῦ κατιδόντες περιόδους χρησαίμεθα ἐπὶ τὰς περιφορὰς τὰς τῆς παρʼ ἡμῖν διανοήσεως, συγγενεῖς ἐκείναις οὔσας, ἀταράκτοις τεταραγμένας, ἐκμαθόντες δὲ καὶ λογισμῶν κατὰ φύσιν ὀρθότητος μετασχόντες, μιμούμενοι τὰς τοῦ θεοῦ πάντως ἀπλανεῖς οὔσας, τὰς ἐν ἡμῖν πεπλανημένας καταστησαίμεθα.
But let this be spoken from us as the cause of this for these purposes: that God found and gave us vision in order that, having observed the circles of mind in heaven, we might use them for the revolutions of our own thinking, which are akin to them, the troubled to the untroubled; and that, having thoroughly learned them and having shared in the correctness of calculations according to nature, by imitating the absolutely unerring circles of God, we might settle the wandering circles in ourselves.
φωνῆς τε δὴ καὶ ἀκοῆς πέρι πάλιν ὁ αὐτὸς λόγος, ἐπὶ ταὐτὰ τῶν αὐτῶν ἕνεκα παρὰ θεῶν δεδωρῆσθαι.
And concerning voice and hearing, again, the same account holds, that they have been gifted by the gods for the same purposes and for the same reasons.
λόγος τε γὰρ ἐπʼ αὐτὰ ταῦτα τέτακται, τὴν μεγίστην συμβαλλόμενος εἰς αὐτὰ μοῖραν, ὅσον τʼ αὖ μουσικῆς φωνῇ χρήσιμον πρὸς ἀκοὴν ἕνεκα ἁρμονίας ἐστὶ δοθέν.
For speech has been appointed for this very purpose, contributing the greatest share to it, and also all that part of music which is useful for hearing has been given for the sake of harmony.
ἡ δὲ ἁρμονία, συγγενεῖς ἔχουσα φορὰς ταῖς ἐν ἡμῖν τῆς ψυχῆς περιόδοις, τῷ μετὰ νοῦ προσχρωμένῳ Μούσαις οὐκ ἐφʼ ἡδονὴν ἄλογον καθάπερ νῦν εἶναι δοκεῖ χρήσιμος, ἀλλʼ ἐπὶ τὴν γεγονυῖαν ἐν ἡμῖν ἀνάρμοστον ψυχῆς περίοδον εἰς κατακόσμησιν καὶ συμφωνίαν ἑαυτῇ σύμμαχος ὑπὸ Μουσῶν δέδοται· καὶ ῥυθμὸς αὖ διὰ τὴν ἄμετρον ἐν ἡμῖν καὶ χαρίτων ἐπιδεᾶ γιγνομένην ἐν τοῖς πλείστοις ἕξιν ἐπίκουρος ἐπὶ ταὐτὰ ὑπὸ τῶν αὐτῶν ἐδόθη.
And harmony, having motions akin to the revolutions of the soul in us, is given by the Muses to him who makes use of them with mind, not for irrational pleasure, as it now seems to be useful, but as an ally for the ordering of the discordant revolution of the soul in us and for bringing it into agreement with itself; and rhythm also, because of the measureless state and that which is deficient in grace which comes to be in most of us, was given as an assistant for the same purposes by the same givers.
τὰ μὲν οὖν παρεληλυθότα τῶν εἰρημένων πλὴν βραχέων ἐπιδέδεικται τὰ διὰ νοῦ δεδημιουργημένα· δεῖ δὲ καὶ τὰ διʼ ἀνάγκης γιγνόμενα τῷ λόγῳ παραθέσθαι.
Now the past part of what has been spoken, except for a few things, has shown the things crafted through mind; but we must also set beside them in our discourse the things that come to be through necessity.
