A closer examination of the subject shows us the motive which causes the right of suffrage to be based upon the supposition of incapacity. The motive is that the elector or voter does not exercise this right for himself alone, but for everybody.
The most extended elective system and the most restricted elective system are alike in this respect. They differ only in respect to what constitutes incapacity. It is not a difference of principle, but merely a difference of degree.
If, as the republicans of our present-day Greek and Roman schools of thought pretend, the right of suffrage arrives with one's birth, it would be an injustice for adults to prevent women and children from voting. Why are they prevented? Because they are presumed to be incapable. And why is incapacity a motive for exclusion? Because it is not the voter alone who suffers the consequences of his vote; because each vote touches and affects everyone in the entire community; because the people in the community have a right to demand some safeguards concerning the acts upon which their welfare and existence depend.
