> Do you know, which one is jefferson's famous quote?

By far, Jefferson's most famous quote is:

"I have sworn upon the altar of God, eternal hostility
against every form of tyranny over the mind of man."
--Thomas Jefferson
This famous quotation is from a letter to
Dr. Benjamin Rush of September 23, 1800.  ME 10:173
But on second thought:  This sounds like a "trick" queston.

Actually, the preamble to the Declaration of Independence is probaby
Jefferson's most famous quotation:

"We hold these truths to be self-evident, that all men are greated equal; 
that they are endowed vy their Creator with certain unalienable rights;
that among these, are life, liberty, and the pursuit of happiness."
