[Footnote 115: What Longinus says about critical skill is applicable here also--[Greek: pollê=s e)/sti pei/ras teleutai=on e)pige/nnêma.] Isokrates (De Permut. Or. xv. sect. 290-312-316) has some good remarks about the impossibility of [Greek: e)pistê/mê] respecting particulars. Plato, in the Gorgias, puts [Greek: te/chnê], which he states to depend upon reason and foreknowledge, in opposition to [Greek: e)mpeiri/a] and [Greek: tribê/], which he considers as dependant on the [Greek: phu/sis stochastikê/]. But in applying the knowledge or skill called Art to particular cases, the [Greek: phu/sis stochastikê\] is the best that can be had (p. 463 A-B). The conception of [Greek: te/chnê] given in the Gorgias is open to the same remark as that which we find in the Phædrus. Plato, in another passage of the Phædrus, speaks of the necessity that [Greek: phu/sis, e)pistê/mê], and [Greek: mele/tê], shall concur to make an accomplished orator. This is very true; and Lysias, Isokrates, and all the other rhetors whom Plato satirises, would have concurred in it. In his description of [Greek: te/chnê] and [Greek: e)pistê/mê], and in the estimate which he gives of all that it comprises, he leaves no outlying ground for [Greek: mele/tê]. Compare Xenophon, Memor. iii. 1, 11; also Isokrates contra Sophistas, a. 16; and a good passage of Dionysius Halik. De Compos. Verborum, in which that rhetor remarks that [Greek: kairo\s] or opportunity neither has been nor can be reduced to art and rule.] [Footnote 116: Plato, Gorgias, pp. 464-465.] [Side-note: Plato's charge against the Rhetorical teachers is not made out.]
