τοὺς τόκους
. The comparison, which is already suggested in
ἀποτείσεις, ἀποδοῦναι (‘pay’ as well as ‘render’), and
κομίσασθαι, culminates in the word
τόκος (‘interest’ and ‘offspring’). See on
γράφειν νόμους 501 A and (for a similar play on
τόκος) cf. VIII 555 E and
Ar.
Thesm. 842
—845.
κίβδηλον below is a metaphor from counterfeit coinage.
διομολογησάμενός γε
. γε (‘yes,’ ‘not until’: cf. with Schneider
Phaedr. 228 D
δείξας γε πρῶτον κτλ.) was restored by Bekker from the best MSS. Stephanus (with
Ξ etc.) read
δέ.
ἐν τοῖς ἔμπροσθεν
. Cf. V 475 E note
εἶναι
is not of course used in its technical sense, otherwise it would be inconsistent with the end of Book V. Socrates means only that the Platonist distinguishes between two categories—
τὰ πολλά, and the Ideas.
καὶ αὐτὸ δὴ κτλ.
The literal meaning of the text above printed is as follows: ‘So likewise a Beautiful itself, and a Good itself and similarly about all which we formerly took’ (or ‘postulated’) ‘as many: reversing our procedure (
πάλιν αὖ), we postulate also one Idea of each, believing that there is but one, and call it the essential so-and-so.’
καὶ—ἐτίθεμεν is best explained as still under the influence of
φαμέν—λόγῳ. τότε (as Schneider observes) refers ‘ad eam, quae modo facta est, multorum commemorationem’: cf. 510 B. Stallbaum is mistaken in supposing that the allusion is to V 475 E ff. Plato's meaning will appear from a single example. We postulate both
πολλὰ δίκαια and also
ἓν δίκαιον, viz. the
ἰδέα μία δικαίου, and we call the latter
ὃ ἔστιν δίκαιον: cf.
Phaed. 75 B
τοῦ ὃ ἔστιν ἴσον,
Symp. 211 C
and elsewhere. We postulate only one
ἰδέα δικαίου, because we believe that there is but one: see X 597 C, D, where Plato shews why there cannot be more. For
αὐτό used of the Ideas, see on IV 438 B, 438 C and V 476 A note Instead of
καὶ ἰδέαν, the MSS— see cr. n.—read
κατ’ ἰδέαν (
κατιδέαν Vind. F.). For the interchange of
καί and
κατά see Schaefer's
Greg. Cor. p. 234 note 26. An unduly sloping accent is enough to account for the corruption of
ΚΑῚΙΔΕΑΝ into
ΚΑΤΙΔΕΑΝ (as in uncial MSS it would be written: see Thompson
Gk. Palaeogr. p. 127). See also my article in
Cl. Rev. XIII p. 100. Other views on the text and interpretation of this difficult passage are discussed in App. VII.
ἆρ’ οὖν κτλ.
On the unique position of Sight among the senses see
Phaedr. 250 D
and Bonitz on Arist.
Met. A 1. 980^{a} 23: cf. also
Phaed. 65 B
,
Tim. 47 A
ff.,
Hipp. Maior 297 E ff. It is the costliest (
πολυτελεστάτη) because it requires an additional precious or valuable element (
μὴ ἄτιμον 508 A) beyond what is necessary for the operation of the others, viz. Light: cf.
Tim. 45 C
, D and Arist.
de An. II 7. 418^{b} 2 ff.
ἔστιν ὅ τι κτλ.
Steinhart (p. 689 note 213) and others remark on Plato's error in denying that a medium is necessary in Hearing etc. Aristotle was well aware of this fact (see his
de An. II 7. 419^{a} 25 ff.), and there are several indications that it was not altogether unknown to Plato. In
Tim. 67 B
, for example, air is regarded as in a certain sense the medium of sound. Here, however, where a scientific analysis of perception is not proposed, Plato takes his stand upon the broad fact of experience, that whereas we can hear, touch, etc. either in light or in darkness, we can see only where there is light.
οὐδ’ ἄλλαις πολλαῖς
. ‘Non
αἰσθήσεσι supplendum est, quippe quae non amplius tres supersint, sed
δυνάμεσι vel
δυνάμεων συζεύξεσι’ (Schneider). It may be added that the antecedent of
ἄλλαις is the same as that of
τινα and
τὴν τῆς ὄψεως καὶ τοῦ ὁρατοῦ, and
τὴν is certainly for
τὴν δύναμιν: cf.
τὴν τοῦ ὁρᾶν τε καὶ ὁρᾶσθαι δύναμιν in C. Plato is thinking quite generally of
δυνάμεις τοῦ ποιεῖν τε καὶ πάσχειν: cf.
Theaet. 156 A
.
ἐν αὐτοῖς κτλ.
If
ἐν αὐτοῖς is right,
αὐτοῖς must be interpreted as
τοῖς ὁρωμένοις, for it is clear from 508 C
ὧν ἂν τὰς χρόας τὸ ἡμερινὸν φῶς ἐπέχῃ that colour is here regarded as inherent in the object. Grammatically, however,
αὐτοῖς can scarcely mean anything except
τοῖς ὄμμασιν, and in my edition of 1897 I accordingly proposed to read
ἐν αὐτοῖς <τοῖς ὁρωμένοις>. Ficinus translates
praesente item colore, omitting
ἐν αὐτοῖς altogether. For other views see App. VIII.
τίνος ‐‐ τούτου
; The genitive has been variously explained as (1) dependent on
γένος (Schneider), (2) in agreement with
παραγενομένου understood (Stallbaum, Campbell), (3) like
ἵππων in
τί δὲ ἵππων οἴει; V 459 B (Jowett). (2) is in my opinion grammatically impossible. For (3) cf. V 470 A note Jowett's view is perhaps possible, but we should have expected simply
τί δὴ λέγεις—τοῦτο; Schneider's explanation (‘Pray what is this whose
γένος you mention?’) is, I think, the least unsatisfactory. Perhaps we should read
δεῖν for
δή .
ὃ δὴ σὺ καλεῖς
. Herwerden needlessly writes
ὃ δὴ καὶ σὺ καλεῖς.
οὐ σμικρᾷ κτλ.
ἰδέα, ‘kind,’ ‘class,’ is here a synonym for
γένος as in
Theaet. 184 D
,
Pol. 289 B
. The dative expresses the ‘amount of difference’ after the comparative
τιμιωτέρῳ (‘more precious:’ cf.
πολυτελεστάτην in 507 C). Cf. II 373 E and IX 579 C
τοῖς τοιούτοις κακοῖς πλείω καρποῦται with note ad loc.
