Here is where the terms get fuzzy. You don't have to define the natural rights
Yes, you do. To argue something exists, you must first define it.
Once defined and demonstrated, they can be enumerated.
Sure they can be enumerated but why bother? As long as it is understood that a natural right is everything that we think or do that requires no participation or contribution from anybody else, who wants to take the lifetime it would require to write down every possible thing that would be included in that? Why isn't it sufficient (for you) to accept that if nobody else has to participate or risk or contribute anything to make it possible, I have the right to do it?
but simply have to agree that those thoughts, concepts, ideas, activities of humankind that require no participation or contribution by any other are so defined natural rights.
Using your definition, I have the 'natural right' to steal and to burn any building to the ground, since it requires no participation or contribution by another person for me to so act.
Perhaps you'd like to rephrase?
If it is your building owned free and clear with no outstanding obligation to any other, and you can burn it to the ground without endangering or infringing on any other, then the Founders would say that it is your unalienable right to dispose of your property however you choose.
To burn somebody elses building or to steal requires unwilling participation and/or contribution of another and therefore that does not fall within the scope of natural rights.
Clarify.
What of wars? Self-defense? Capital punishment?
Wars and/or capital punishment are or at least should be included in the social contract as the means to secure and protect the unalienable, legal, civil, and constitutional rights of the people. The social contract will include consequences for violating the rights of others, else there is no other means by which the peoples' government can secure and protect those rights.
Self defense of course does defend and protect our rights when another presumes to violate them.
Such a concept as sacrosanct life is purely a human invention primarily rooted in and justified using religion.Nature shows no such principle in action when a lion eats a gazelle or a man succumbs to ebola.
Indeed the very use of the term 'sacrosanct' reveals the religious nature and roots of your claims.
You call it human invention. The Founders saw it as God given and yes, there was a strong religious underpinning to the concept. The Founders, almost to a man, were of deep religious faith and, almost to a man, knew that the Constitution would not be protected and defended by other than a religious and moral people. Neverthless, they also recognized that religion misused can also be a force that usurps natural rights and ensured that while government would not be able to infringe on religious beliefs and practices, neither would government be placed under any religious or any other authority other than that of the people as a whole.
Demonstrate that:
A - your god exists
B - these 'rights' exist
C - your god bestowed or granted these 'natural rights'
Why? What does that possibly have to do with the concept or principle stated?
and it includes seeking or doing that which will preserve and sustain our lives.
theft?
Theft requires participation/contribution of somebody else and therefore it is not a natural right to steal from somebody else.
It does not include requiring another to provide that for us.
Because yo do not wish to provide? You merely make assertions regarding what rights you claim do or do not exist. Assertion =/= demonstration.
It does not fall within the scope of natural rights for me to demand or require you to provide me with anything, nor you to demand or require that I provide you with anything.
