Obviously not. So, for example, some are more capable of discerning Jefferson's intent than others.
The quote in question reads:
“We hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness….”
Let's give Jefferson the benefit of the doubt and assume that he was not a moron, and that he was perfectly aware that, for example, some are created larger, or heavier, or ... the list is near endless. So the question becomes: What might he have had in mind?
Perhaps context would help. So, what about:
“We hold these Truths to be self-evident, that all Men are created equal, [in] that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness….”
Wow! Could it really be that simple?
