The framers of the Constitution were the best and the brightest of their day. They took great pains to consider as many possibilities as possible including the ability to expand the document if necessary. While many things have changed as our society as grown and developed, the core values remain the same and should stay that way. Improvements can be made and have, but the document and ideas behind remain virtually the same as they did in 1787.
“I'm not at all well versed in what Jefferson or Madison wrote in their private papers about what exactly constituted privacy when they wrote the Constitution. Does it matter? We don't live in 1787, we live in 2008.”
Actually it matters a great deal. If you want to value a historical document full of ideas that you say you believe in then you must know what the authors of that document thought. Without an understanding of the past you have no hope for a future. You have nothing to base your opinions on and end up talking out of your ass.
“Scalia's "originalism" doesn't seem to take into account the changes that have moved the government far from it's original definitions. For instance, what exactly is a militia today? What we call the Guard and the Active Services are no longer what were understood in 1787. How can one apply originalism to a concept that no longer represents what the Constitutional authors understood it to be?”
While the definitions of some words have changed over time, most of them have remained the same. The founding fathers took great pains to choose words that they were sure would never lose their meaning and they did a very good job.
A militia today is virtually the same thing it was in 1787, which is a body of citizens that have organized into a paramilitary group and are used in emergencies that are considered a threat to government or public safety and requires an armed response. This is what it meant in 1787 and that is what it means in 2008.
The Guard and the Active Services have expanded and evolved over time with technology and as the needs of their services changed, but they are virtually the same as well.
If the meaning hasn’t changed enough to lose its perspective or accuracy then there is no reason to stop using it.
