διέλυσεν καὶ ἀπώλεσεν
. Throughout this argument, as throughout the
Phaedo, destruction means dissolution (
διάλυσις).
τὸ ξύμφυτον κτλ.
The words
ἑκάστου and
ἀπολεῖ are bracketed by Herwerden, quite undeservedly. For the statement itself see on 609 E.
ἦν
. “Imperfectum illud tempus indicat, quo res nondum satis cognita, et tamen ita, ut nunc apparet, comparata esset” Schneider. Cf. IV 436 C note
ἀδικία ‐‐ ἀμαθία
. Vice is the evil peculiar to soul: cf. IV 444 C,
Tim. 86 B
ff. and
Soph. 227 E
.
ἀλλ) ὧδε ποίει
. ποίει means ‘picture,’ ‘represent.’
που οἴει, which Liebhold conjectures (
Philol. 1880 p. 169), is wholly inapposite; for the sense requires an imperative. Ast suggests
νόει or
σκόπει, but the text is sound: see on VII 498 A.
ἕως ἂν ‐‐ χωρίσῃ
. θάνατον must here be understood of the
soul's death, otherwise the parallel with
ὥσπερ —ἀφικνεῖται breaks down, and the reasoning becomes not merely fallacious, but absurd. We have, in fact, to distinguish between the death or dissolution of a the body (as described in C above
ὥσπερ σῶμα — εἰς τὸ μηδὲ σῶμα εἶναι), b the soul, c the
σύνολον, or body
plus soul. If the soul is mortal, the moment at which it is dissolved and perishes is when the
σύνολον dies, i.e. (
Phaed. 64 C
, 67 D) when soul is separated from body (cf.
Phaed. 70 A
, 77 B, D, E, 80 D and 84 B). Plato reminds us of this by saying
ἕως ἂν εἰς θάνατον ἀγαγοῦσα τοῦσώματος χωρίσῃ instead of merely
ἕως ἂν εἰς θάνατον ἀγάγῃ. Cf. 610 D note
οὐδαμῶς ‐‐ τοῦτό γε
. It is strange that Glauco should assent so readily. He is apparently thinking (as in 610 E) of the activity and vitality which wicked men so frequently display; but we may fairly ask ‘Why should soul be the only thing which is incapable of being destroyed by its own vice?’ It would surely be more true to hold that vice is able to kill the soul just
because it is able
ποιεῖν αὐτὴν κακήν (609 B), and Panaetius actually made use of a similar argument in order to prove the soul mortal (“nihil esse, quod doleat, quin id aegrum esse quoque possit. quod autem in morbum cadat, id etiam interiturum; dolere autem animos, ergo etiam interire” Cicero
Tusc. Disp. I 79). Is
ἆρα ἐνοῦσα—χωρίσῃ intended as an appeal to experience? Even if we allowed that experience is the proper tribunal, our experience of the effect of injustice on a human soul is limited to a single life; and why should not one soul wear out many bodies and perish at last through its own vice
καὶ ᾖ αὐτὸ τοῦτο θάνατος, ψυχῆς ὄλεθρος (cf.
Phaed. 87 B
, 91 D. See also Deichert
Plato's Beweise f. die Unsterblichkeit d. Seele pp. 46—48). These difficulties are serious, and possibly fatal: they have even led some critics to stigmatise the whole argument as a
petitio principii (e.g. Brandt
Zur Entwick. d. Pl. Lehre v. d. Seelentheilen p. 29). Plato does not attempt to solve them here; but a comparison of the present argument with
Phaed. 93 A
—94 B helps at all events to explain his position. Soul is always soul, and no soul is more a soul than any other (
Phaed. 93 B
); hence the soul which is made evil by vice retains its vitality unimpaired. It is in fact the conception of soul as the principle of life which explains (from the Platonic point of view) Glauco's emphatic
οὐδαμῶς. Cf. I 353 D
τί δ) αὖ τὸ ζῆν; ψυχῆς φήσομεν ἔργον εἶναι; Μάλιστά γ), ἔφη, with note ad loc. It is on the essential connexion between ‘soul’ and ‘life’ that Plato builds his crowning argument for the immortality of the soul in the
Phaedo (100 B ff., and especially 105 C, D). Cf. Zeller^{4} II p. 827 and infra 610 D note
αὐτῶν ‐‐ τῶν σιτίων
. Herwerden (following
Ξ) would omit
τῶν σιτίων, but the contrast with
σώματος μοχθηρίαν is improved by the presence of these words.
αὐτῶν is ‘ipsorum’ exactly as in
αὐτῶν ἐκείνων above: ‘of food itself’ )( body.
ὑπὸ δὲ σιτίων κτλ.
Cf. 609 A, B. It is difficult to see where the
ἔμφυτον κακόν comes in when the organism is destroyed by violence. Surely fire destroys wood without using
σηπεδών as its instrument. The fact is that Plato's theory of a
ξύμφυτον κακόν by which and which alone each object is destroyed, if destroyed it be, does not apply except where the object is independent of external influences, and such, throughout this proof, he supposes soul to be. Cf. 608 D note and Brandt l.c. p. 29.
