Considering that the word "natural" doesn't appear in the amendment, I don't consider it all that compelling. The framers were more than familiar with the concept of "natural rights" and so could have used the phrase if they thought it appropriate. Evidently they didn't.
They refferenced it dozens of times in the debates before the Dec of Ind and the Constitution.
The concept that your rightS come from your humanity or God isnt always referred to as "natural rights". The Dec of Independence is our mission statement saying why we have the right to exist as a separate government. The Constituion is a set of laws based on that. There wouldn't be many reasons to continually explain this as it was universally understood.
This whole discipussion is bizzare. All you need to do is Google "natural rights or natural law" and "US Constituion" and then spend the next week reading it explain 1000 different ways
The Federalist and Anti Federalist papers were a series of articles discussing the reasoning behind the proposed Constituion that had not yet been ratified. In AntiFederalist #2 Robert Yates wrote:
"The common good, therefore, is the end of civil government, and common consent, the foundation on which it is established. To effect this end, it was necessary that a certain portion of
natural liberty should be surrendered, in order, that what remained should be preserved: . . . But it is not necessary, for this purpose, that individuals should relinquish all their
natural rights. Some are of such a nature that they cannot be surrendered.
Of this kind are the rights of conscience, the right of enjoying and defending life, etc. Others are not necessary to be resigned, in order to attain the end for which government is instituted, these therefore ought not to be given up. . . . The same reasons which at first induced mankind to associate and institute government, will operate to influence them to observe this precaution. If they had been disposed to conform themselves to the rule of immutable righteousness, government would not have been requisite. It was because one part exercised fraud, oppression, and violence on the other, that men came together, and agreed that certain rules should be formed, to regulate the conduct of all, and the power of the whole community lodged in the hands of rulers to enforce an obedience to them. But rulers have the same propensities as other men; they are as likely to use the power with which they are vested for private purposes, and to the injury and oppression of those over whom they are placed, as individuals
in a state of nature are to injure and oppress one another. It is therefore as proper that bounds should be set to their authority, as that government should have at first been instituted to restrain private injuries"
Just one of MANY examples
