Democracy and Responsibility

It is commonly believed that if a member of a Democracy does not vote, they might be foolishly missing an opportunity to influence the general condition, but not that they are evading a responsibility to do so.  But, entailed in such a belief is the concept of the Individual as essentially independent of Society, a concept rooted in that of the supernatural Soul that is a cardinal feature of Medieval Theology.  In contrast, on the premises that every Person is a part of Humankind, and that a Society is only as strong as its weakest Member, each citizen in a Democracy does have a Responsibility to every other, and to the Polity as a whole, to participate in the processes that define it as such.  So, whether or not there is a Responsibility to vote in a Democracy depends on some fundamental presuppositions that are rarely addressed in common conversation.
