"[W]e shall observe that Jewish intellectual qualities have remained constant, that certain characteristics, certain peculiar features of the Jewish soul may be traced as far back as the formation of the Jewish ethnical group. We cannot prove all this directly, because we have no reliable accounts of the Jewish popular character dating from early times. What we do possess are brief and scanty expressions of opinions, valuable, however, as far as they go. It is of great interest, for example, to note that the Pentateuch (in four places— Exod. xxxii. 9, xxxiv. 9; Deut. ix. 13 and 27) asserts of the Jews what Tacitus said of them later—that they are a stiff-necked people. No less interesting is Cicero’s statement that they hang together most fraternally, or Marcus Aurelius’s that they are a restless people, to whom he cries, “O ye Marcomanni, O ye Quadi, O ye Sarmatae, at length have I found a race more restless than you!”; or finally Juan de la Huarte's that their intellect is keen and well fitted for worldly things. [...] Under the Caesars their lot [the Jews] was no different [than in other nations of antiquity]: “I am just sick of these filthy, noisy Jews,” said Marcus Aurelius."
