A similar admonition is addressed (in the Parmenidês, p. 130 E) by the old Parmenides to the youthful Sokrates, when the latter cannot bring himself to admit that there exist εἶδη or Forms of vulgar and repulsive objects, such as θρὶξ and πῆλος. Νεος γὰρ εἶ ἔτι, καὶ οὔπω σοῦ ἀντείληπται φιλοσοφία ὡς ἔτι ἀντιλήψεται κατ’ ἐμὴν δόξαν, ὅτε οὐδὲν αὐτῶν ἀτιμάσεις· νῦν δ’ ἔτι πρὸς ἀνθρώπων ἀποβλέπεις δόξας διὰ τὴν ἡλικίαν.
See above, [ch. xxvii. p. 60], in my review of the Parmenidês.
In a logical classification, low and vulgar items deserve as much attention as grand ones. Conflict between emotional and scientific classification.
This precept (repeated by Plato also in the Politikus) respecting the principles of classification, deserves notice. It protests against, and seeks to modify, one of the ordinary turns in the associating principles of the human mind. With unreflecting men, classification is often emotional rather than intellectual. The groups of objects thrown together in such minds, and conceived in immediate association, are such as suggest the same or kindred emotions: pleasure or pain, love or hatred, hope or fear, admiration, contempt, disgust, jealousy, ridicule. Community of emotion is a stronger bond of association between different objects, than community in any attribute not immediately interesting to the emotions, and appreciable only intellectually. Thus objects which have nothing else in common, except appeal to the same earnest emotion, will often be called by the same general name, and will be constituted members of the same class. To attend to attributes in any other point of view than in reference to the amount and kind of emotion which they excite, is a process uncongenial to ordinary taste: moreover, if any one brings together, in the same wording, objects really similar, but exciting opposite and contradictory emotions, he usually provokes either disgust or ridicule. All generalizations, and all general terms connoting them, are results brought together by association and comparison of particulars somehow resembling. But if we look at the process of association in an unreflecting person, the resemblances which it fastens upon will be often emotional, not intellectual: and the generalizations founded upon such resemblances will be emotional also.
It is against this natural propensity that Plato here enters his protest, in the name of intellect and science. For the purpose of obtaining a classification founded on real, intrinsic affinities, we must exclude all reference to the emotions: we must take no account whether a thing be pleasing or hateful, sublime or mean:[24] we must bring ourselves to rank objects useful or grand in the same logical compartment with objects hurtful or ludicrous. We must examine only whether the resemblance is true and real, justifying itself to the comparing intellect: and whether the class-term chosen be such as to comprise all these resemblances, holding them apart (μόνον ἐχέτω χωρὶς) from the correlative and opposing class.[25]

We see that Plato has thus both anticipated and replied to the objection of Socher (Ueber Platon’s Schriften, pp. 260-262), who is displeased with the minuteness of this classification, and with the vulgar objects to which it is applied. Socher contends that this is unworthy of Plato, and that it was peculiar to the subtle Megaric philosophers.
I think, on the contrary, that the purpose of illustrating the process of classification was not unworthy of Plato; that it was not unnatural to do this by allusion to vulgar trades or handicraft, at a time when no scientific survey of physical facts had been attempted; that the allusion to such vulgar trades is quite in the manner of Plato, and of Sokrates before him.
Stallbaum, in his elaborate Prolegomena both to the Sophistês and to the Politikus, rejects the conclusion of Socher, and maintains that both dialogues are the work of Plato. Yet he agrees to a certain extent in Socher’s premisses. He thinks that minuteness and over-refinement in classification were peculiarities of the Megaric philosophers, and that Plato intentionally pushes the classification into an extreme subtlety and minuteness, in order to parody their proceedings and turn them into ridicule. (Proleg. ad Sophist. pp. 32-36, ad Politic. pp. 54-55.)
But how do Socher and Stallbaum know that this extreme minuteness of subdivision into classes was a characteristic of the Megaric philosophers? Neither of them produce any proof of it. Indeed Stallbaum himself says, most truly (Proleg. ad Politic. p. 55) “Quæ de Megaricorum arte dialecticâ accepimus, sane quam sunt paucissima”. He might have added, that the little which we do hear about their dialectic, is rather adverse to this supposed minuteness of positive classification, than consonant with it. What we hear is, that they were extremely acute and subtle in contentious disputations — able assailants of the position of a logical opponent. But this talent has nothing to do with minuteness of positive classification: and is even indicative of a different turn of mind. Moreover, we hear about Eukleides, the chief of the Megaric school, that he enlarged the signification of the Summum Genus of Parmenides — the Ἓν καὶ Πᾶν. Eukleides called it Unum, Bonum, Simile et Idem Semper, Deus, &c. But we do not hear that Eukleides acknowledged a series of subordinate Genera or Species, expanding by logical procession below this primary Unum. As far as we can judge, this seems to have been wanting in his philosophy. Yet it is exactly these subordinate Genera or Species, which the Platonic Sophistês and Politikus supply in abundance, and even excess, conformably to the precept laid down by Plato in the Philêbus (p. 14). The words of the Sophistês (p. 216 D) rather indicate that the Eleatic Stranger is declared not to possess the character and attributes of Megaric disputation.
