Sokrates agrees with them in part, but not wholly _ib._ Theory of the pleasure-haters--We must learn what pleasure is by looking at the intense pleasures--These are connected with distempered body and mind 355 The intense pleasures belong to a state of sickness; but there is more pleasure, on the whole, enjoyed in a state of health 356 Sokrates acknowledges some pleasures to be true. Pleasures of beautiful colours, odours, sounds, smells, &c. Pleasures of acquiring knowledge _ib._ Pure and moderate pleasures admit of measure and proportion 357 Pleasure is generation, not substance or essence: it cannot therefore be an End, because all generation is only a means towards substance--Pleasure therefore cannot be the Good _ib._ Other reasons why pleasure is not the Good 358 Distinction and classification of the varieties of Knowledge or Intelligence. Some are more true and exact than others, according as they admit more or less of measuring and computation _ib._ Arithmetic and Geometry are twofold: As studied by the philosopher and teacher: As applied by the artisan 359 Dialectic is the truest and purest of all Cognitions. Analogy between Cognition and Pleasure: in each, there are gradations of truth and purity 360 Difference with Gorgias, who claims superiority for Rhetoric. Sokrates admits that Rhetoric is superior in usefulness and celebrity: but he claims superiority for Dialectic, as satisfying the lover of truth _ib._ Most men look to opinions only, or study the phenomenal manifestations of the Kosmos. They neglect the unchangeable essences, respecting which alone pure truth can be obtained 361 Application. Neither Intelligence nor Pleasure separately, is the Good, but a mixture of the two--Intelligence being the most important. How are they to be mixed? _ib._ We must include all Cognitions--not merely the truest, but the others also. Life cannot be carried on without both 362 But we must include no pleasures except the true, pure, and necessary. The others are not compatible with Cognition or Intelligence--especially the intense sexual pleasures _ib._ What causes the excellence of this mixture? It is Measure, Proportion, Symmetry. To these Reason is more akin than Pleasure 363 Quintuple gradation in the Constituents of the Good. 1. Measure. 2. Symmetry. 3. Intelligence. 4. Practical Arts and Right Opinions. 5. True and Pure Pleasures 364 Remarks. Sokrates does not claim for Good the unity of an Idea, but a quasi-unity of analogy 365 Discussions of the time about Bonum. Extreme absolute view, maintained by Eukleides: extreme relative by the Xenophontic Sokrates. Plato here blends the two in part; an Eclectic doctrine _ib._ Inconvenience of his method, blending Ontology with Ethics 366 Comparison of Man to the Kosmos (which has reason, but no emotion) is unnecessary and confusing 367
