But Cicero does not seem even to have had a religious sentiment to cover the nakedness of his political opportunism. Not only does he in the Tusculan Disputations put aside in the Platonic fashion all the Homeric tales which anthropomorphize and discredit the gods; but in his treatise On Divination he shows an absolute disbelief in all the recognized practices, including the augury which he himself officially practised; and his sole excuse is that they are to be retained “on account of popular opinion and of their great public utility.”
