1. GOOD AND PLEASURE.—That the highest good can be nothing other than the idea of the good itself, has already been shown in the dialectics, where this idea was suffered to appear as the ultimate end of all our striving. But since the dialectics represent the supreme good as unattainable by human reason, and only cognizable in its different modes of manifestation, we can, therefore, only follow these different manifestations of the highest good, which represent not the good itself, but the good in becoming, where it appears as science, truth, beauty, virtue, &c. We are thus not required to be equal to God, but only like him (_Theæt._) It is this point of view which lies at the basis of the graduated table of good, given in the Philebus. In seeking the highest good, the conception of pleasure must be investigated. The Platonic standpoint here is the attempt to strike a balance between Hedonism, (the Cyrenian theory that pleasure is the highest good, _cf._ § XIII. 3), and Cynicism. While he will not admit with Aristippus that pleasure is the true good, neither will he find it as the Cynics maintain, simply in the negation of its contrary, pain, and thus deny that it belongs to the good things of human life. He finds his refutation of Hedonism in the indeterminateness and relativity of all pleasure, since that which at one time may seem as pleasure, under other circumstances may appear as pain; and since he who chooses pleasure without distinction, will find impure pleasures always combined in his life with more or less of pain; his refutation of Cynicism he establishes by showing the necessary connection between virtue and true pleasure, showing that there is a true and enduring pleasure, the pleasure of reason, found in the possession of truth and of goodness, while a rational condition separate from all pleasure, cannot be the highest good of a finite being. It is most prominently by this distinction of a true and false, of a pure and impure pleasure, that Plato adjusts the controversy of the two Socratic schools.—A detailed exhibition of the Philebus we must here omit.—On the whole, in the Platonic apprehension of pleasure, we cannot but notice that same vacillation with which Plato every where treats of the relation between the corporeal and the spiritual, at one time considering the former as a hindrance to the latter, and at another as its serving instrument; now, regarding it as a concurring cause to the good, and then, as the ground of all evil; here, as something purely negative, and there, as a positive substratum which supports all the higher intellectual developments; and in conformity with this, pleasure is also considered at one time as something equivalent to a moral act, and to knowledge, and at another as the means and accidental consequence of the good.
