perhaps
From LSJ
κακοὶ μάρτυρες ἀνθρώποισιν ὀφθαλμοὶ καὶ ὦτα βαρβάρους ψυχὰς ἐχόντων → eyes and ears are poor witnesses for men if their souls do not understand the language (Heraclitus Phil.: Fr. B 107; Testimonia: Fragment 16, line 6)
English > Greek (Woodhouse)
adverb
to make as assertion less strong: P. and V. σχεδόν τι.
perhaps I do not put your nature to shame: V. σχεδόν τι τὴν σὴν οὐ καταισχύνω φύσιν (Soph., Electra 609).
perhaps you are right: P. κινδυνεύεις ἀληθῆ λέγειν (Plato, Symposium 205D).
