The Federalist Papers

I find it interesting that in the Federalist Papers there is a lot of emphasis on natural rights. This is very John Locke. It seams that the founding fathers didn't try too hard to hide the fact that much of the ideology that shaped, and continues to shape, the US is based off Lockean principles. Personally I find the idea of natural rights to be little strong, because human beings have always been social creatures, and much of our behavior is socially constructed. We were never alone and in a natural state as Locke proposed.
