From LSJ

ἐν μὲν γὰρ εἰρήνῃ καὶ ἀγαθοῖς πράγμασιν αἵ τε πόλεις καὶ οἱ ἰδιῶται ἀμείνους τὰς γνώμας ἔχουσι διὰ τὸ μὴ ἐς ἀκουσίους ἀνάγκας πίπτειν → in peace and prosperity states and individuals have better sentiments, because they do not find themselves suddenly confronted with imperious necessities
