Thank you for the response!
Granted in its entirety! Thanks for the clarification, as I didn't intend to imply that NAP is dependent on Stef's existence or change the definition of self-defense.
Also, I am currently moving through Stef's intro to philosophy playlist, though it is quite lengthy so I'll be at it awhile.
However, here is where I get hung up:
We accept that it is ethical for a person to use force to secure promises made to them. This is perfectly reasonable and I agree completely.
We also accept that a group of people has the same ethical rights and responsibilities as any member of the group; just because there is a group of people that come together, does not mean that simply by being call a "society" the group loses any rights or gains any privileges that any of its individuals have or do not have.
Thus it is ethical for a group of people to use force to secure promises made to members of the group or made to everyone in the group.
For a person to be a member of a group, that person will usually have to make some sort of promise to the rest of the group members regarding their behavior. This promise can be explicit (as in an employment contract or an oath of citizenship) or implicit (few group members explicitly affirm their allegiance to each and every law and social custom of a group, especially those members born into a group). Also, for reasons of practicality and especially in large groups, a group member who makes this promise is assumed to have made this promise to all members, regardless if they are present or not.
Thus it appears to be ethical for a group of people to use force to secure the explicit or implicit promises made by its members to each other.
In large groups, members will find it practical to devise some way of appointing leaders. These leaders will be able to make decisions for the group's members as limited by the rules of the group (we usually call these rules a constitution). These leaders are usually also empowered by those rules to use force to secure promises, implicit or explicit, made to members of the group.
So here comes the big question:
Given that all of the above naturally flows from "it is ethical for a person to use force to secure promises made to them," is it not also ethical for a government to use force upon its own citizens to secure its laws, provided that force is provided for by its constitution?
