An Athenian citizen does not neglect his state because he takes care of his own household; even those of us who are engaged in business have a very fair idea of politics. We do not regard a man who takes no interest in public affairs as harmless. We do not say that such a man 'minds his own business'. Rather we say he has no business here at all.
