A "On the highest"] Thus the Savile manuscript reads correctly original: peri tēs anōtatō, not as in the printed editions, "through the highest," or the Breslau manuscript, "most highest." See what Henri Estienne noted below regarding the words in Chapter 1, Section 4: "Whence it reasonably seems that the highest Philosophies are three." So also in the title of Chapter 13: "on the general modes." Section 138: "the highest kinds." Book 2, Section 205: "the highest chapters." Book 3, Section 64: "the highest assertions concerning motion." So too in Book 2, Against the Physicists, Sections 38, 45, and 276. Book 1, Against the Mathematicians, Section 26: "the double difference of bodies according to the highest degree." Section 36: "the highest graces." Section 88: "of all those in general and the highest." Section 100: "according to the highest." Book 1, Against the Logicians, Section 47: "the highest assertions." Section 364: "the highest matters." Book 2, Section 141: "a double difference according to the highest." Book 1, Against the Physicists, Section 39: "the highest reflection." Perhaps in Section 117 we should read "the highest reason" for "highest." Book 1, Against the Physicists, Section 159: "concerning the highest elements."
B "which modes"] It was poorly printed as "which of the modes," for all manuscripts read "which modes."
C "to every argument an equal argument"] This is more correctly rendered (as Henri Estienne himself admits elsewhere) as "equal reason" original: parem rationem rather than "equal speech," for Sextus expressly testifies that he understands "reason" original: logon as that which "establishes something dogmatically." Cicero says in the Lucullus, chapter 40: "In most things, the weights of contrary reasons are equal." And in the Academics, Book 1, final chapter: "so that when in the same matter equal weights of reasons were found in contrary parts, assertion might more easily be withheld from both sides."
D "the Sceptic Expressions"] Thus the Savile manuscript reads correctly original: tōn Skeptikōn Phōnōn, instead of "the Sceptic Expression" (singular) which was in the earlier edition, and the Breslau manuscript's "concerning the Sceptic Expression." In both manuscripts, the following chapter titles are formulated in these words: 29. "Whether the Sceptic way leads to the Heraclitean Philosophy." 30. "Whether the Democratean sect differs from Scepsis." 31. "Whether the Cyrenaic differs from Scepsis." 32. "Whether the Protagorean differs from Scepsis." 33. "Whether the Scepsis of the Academics differs." But for more than one reason, it is clear to me that the chapter divisions and inscriptions are not by Sextus himself. See, if you please, what is written below regarding Book 3, chapter 30.
