critically evaluate Aristotle theory of citizenship?

The first matter of investigation is the definition of citizenship. Different regimes define citizenship in different ways. Some are citizens only in a qualified sense‹like children who are not old enough to participate in the affairs of the city or elders who have been relieved are their civic duties. In an unqualified sense, the citizen is one who shares in holding office and making decisions. This type of citizen in the unqualified sense really only exists in a democracy. In general, one can say that whoever is entitled to participate in an office‹even if he actually does not do so‹ is a citizen.
