I don't know about that. I was just reading the chapter in Poor Richard's Almanac which compares indian civility to white civility. Funny passage. Written in the 1750's. Clearly looks outside its scope.
"We hold these truths to be self evident..."
They must have seen it too. George Washington was a fierce land speculator. Employed Daniel Boone to go and fight indians for him, so that he could procure more land. They evidently agreed with you, annalex, that the right to property is actually obtained by brute force.
I take my statement in #10 back, in the sense that academically, one can visualize things beyond the horizon, but constitution-writing is not an academic exercise. It is notable that Jefferson replaced "pursuit of property" with "pursuit of happiness" in the final draft, recognizing that "property" doesn't have, academically, a clear meaning.
