So the depravity of man and the resultant need for separation of powers is not a biblical principle?<quoted text>
That's Christian disinformation that originated with a man named William Federer in a book entitled, "America's God and Country." From http://candst.tripod.com/tnppage/montesquieu....
"According to Federer, the Jeremiah passage provides the motive for separated powers ... The problem with Federer's argument is that it is not true. Montesquieu develops his argument for separation of powers in Book XI of The Spirit of the Laws, and nowhere in this book does he reference Isaiah, Jeremiah, or any other book of the Bible. On the contrary, Montesquieu's examples in this section are all drawn from contemporary European and pre-Christian Roman and Germanic history. Nor can we find references to Isaiah and Jeremiah elsewhere in the book."
This is Christian (historical) revisionism, and you are serving as its vector uncritically. After a few years of exposure to this kind of thing, one comes to know the Christian's motivations and scholastic values, and just tunes them out.
Trying to give god beliefs credit for anything constructive will be difficult for you.
You don't see privacy as a god given natural right then? You may be correct. It certainly isn't a biblical principle. Humanists fixed that - for awhile.
No, you are wrong. I have not seen Federer's book, but I quickly found other sources referencing Montesquieu's use of biblical passages. And the Puritans and Calvinists who were prevalent during the founding era used it. That Jeremiah 17:9, or the Bible in general, was not of influence in separation of powers is preposterous.
On the specific point of whether Montesquieu expressed his idea as based on Jeremiah 17:9, I cannot prove it. So I retract it.
On the right to privacy, it is not a question of god-given rights. What was handed down is that it is a Constitutional Right - a right protected by the Bill of Rights of the U.S. Constitution.
It is not.
