In like manner, with respect to boys who are not yet enrolled, or old men who are past war, we admit that they are in some respects citizens, but not completely so, but with some exceptions, for these are not yet arrived to years of maturity, and those are past service; nor is there any difference between them. But what we mean is sufficiently intelligible and clear, we want a complete citizen, one in whom there is no deficiency to be corrected to make him so. As to those who are banished, or infamous, there may be the same objections made and the same answer given. There is nothing that more characterises a complete citizen than having a share in the judicial and executive part of the government.
With respect to offices, some are fixed to a particular time, so that no person is, on any account, permitted to fill them twice; or else not till some certain period has intervened; others are not fixed, as a juryman's, and a member of the general assembly: but probably some one may say these are not offices, nor have the citizens in these capacities any share in the government; though surely it is ridiculous to say that those who have the principal power in the state bear no office in it.
But this objection is of no weight, for it is only a dispute about words; as there is no general term which can be applied both to the office of a juryman and a member of the assembly. For the sake of distinction, suppose we call it an indeterminate office: but I lay it down as a maxim, that those are citizens who could exercise it.
Such then is the description of a citizen who comes nearest to what all those who are called citizens are. Every one also should know, that of the component parts of those things which differ from each other in species, after the first or second remove, those which follow have either nothing at all or very little common to each.
