Plato, Laws 900b

θεούς, εἰς τοῦτο νῦν τὸ πάθος ἐλήλυθας, ὥστʼ εἶναι μὲν δοκεῖν αὐτούς, τῶν δὲ ἀνθρωπίνων καταφρονεῖν καὶ ἀμελεῖν πραγμάτων. ἵνα οὖν μὴ ἐπὶ μεῖζον ἔλθῃ σοι πάθος πρὸς ἀσέβειαν τὸ νῦν παρὸν δόγμα, ἀλλʼ ἐάν πως οἷον ἀποδιοπομπήσασθαι λόγοις αὐτὸ προσιὸν γενώμεθα δυνατοί, πειρώμεθα, συνάψαντες τὸν ἑξῆς λόγον ᾧ πρὸς τὸν τὸ παράπαν οὐχ ἡγούμενον θεοὺς ἐξ ἀρχῆς διεπερανάμεθα,

to repudiate the gods, you have come to your present morbid state of mind, in which you opine that the gods exist, but scorn and neglect human affairs. In order, therefore, that your present opinion may not grow to a greater height of morbid impiety, but that we may succeed in repelling the onset of its pollution (if haply we are able) by argument, let us endeavor to attach our next argument to that which we set forth in full to him who utterly disbelieves gods, and thereby to employ the latter as well.
