10. Finally, do not even the leaders and founders of the schools223    Sententiarum is read in the first ed. by Gelenius, Canterus, and Ursinus, and seems from Crusius to be the ms. reading. The other edd., however, have received from the margin of Ursinus the reading of the text, sectarum. already mentioned, say those very things224    In the first ed., and that of Ursinus, the reading is, nonne apud ea, “in those things which they say, do they not say,” etc., which Gelenius emended as in the text, nonne ipsa ea. which they do say through belief in their own ideas? For, did Heraclitus see things produced by the changes of fires? Thales, by the condensing of water?225    Cf. Diog. Lært. ix. 9, where Heraclitus is said to have taught that fire—the first principle—condensing becomes water, water earth, and conversely; and on Thales, Arist., Met., A, 3, where, however, as in other places, Thales is merely said to have referred the generation and maintenance of all things to moisture, although by others he is represented as teaching the doctrine ascribed to him above. Cf. Cic., de Nat. Deor., i. 10, and Heraclides, Alleg. Hom., c. 22, where water evaporating is said to become air, and settling, to become mud.Did Pythagoras see them spring from number?226    There is some difficulty as to the reading: the ms., first ed., and Ursinus give numero s-c-ire, explained by Canterus as meaning “that numbers have understanding,” i.e., so as to be the cause of all. Gelenius, followed by Canterus, reads -os scit—“does Pyth. know numbers,” which is absurdly out of place. Heraldus approved of a reading in the margin of Ursinus (merely inserting o after c), “that numbers unite,” which seems very plausible. The text follows an emendation of Gronovius adopted by Orelli, -o ex-ire.Did Plato see the bodiless forms? Democritus, the meeting together of the atoms? Or do those who assert that nothing at all can be comprehended by man, know whether what they say is true, so as to227    So the ms., reading ut; but Orelli, and all edd. before him, aut—“or do they.” understand that the very proposition which they lay down is a declaration of truth?228    i.e., that truth knowable by man exists. Since, then, you have discovered and learned nothing, and are led by credulity to assert all those things which you write, and comprise in thousands of books; what kind of judgment, pray, is this, so unjust that you mock at faith in us, while you see that you have it in common with our readiness of belief?229    So the ms. reading nostra in-credulitate, for which Ursinus, followed by Stewechius, reads nostra cum. Heraldus conjectured vestra, i.e., “in your readiness of belief,” you are just as much exposed to such ridicule. But you say you believe wise men, well versed in all kinds of learning!—those, forsooth, who know nothing, and agree in nothing which they say; who join battle with their opponents on behalf of their own opinions, and are always contending fiercely with obstinate hostility; who, overthrowing, refuting, and bringing to nought the one the other’s doctrines, have made all things doubtful, and have shown from their very want of agreement that nothing can he known.

X. Ipsi denique principes, et praedictarum patres sectarum , nonne ipsa ea quae dicunt, suis credita suspicionibus dicunt? Vidit enim Heraclitus res 0825A ignium conversionibus fieri? concretione aquarum Thales? Pythagoras numero exire? incorporales formas Plato? individuorum Democritus concursiones? aut illi, qui autumant nihil posse omnino comprehendi, an sit verum quod dicunt, sciunt: aut ipsum, quod definiunt, veritatis esse intelligunt pronuntiatum? Cum igitur comperti nihil habeatis et cogniti, omniaque illa, quae scribitis, et librorum comprehenditis millibus, credulitate asseveratis duce: quaenam haec est judicatio tam injusta, ut nostram derideatis fidem, quam vos habere conspicitis nostra in credulitate communem? Sed sapientibus vos viris omnibus instructis disciplinarum generibus creditis? nempe illis, qui nihil sciscunt, nec pronuntiant unum; qui pro suis sententiis bella cum adversantibus conserunt, 0825B et pervicacia semper digladiantur hostili; qui cum alter alterius labefactant, destruunt, convelluntque decreta, cuncta incerta fecerunt, nec posse aliquid sciri ex ipsa dissensione monstrarunt.
