George Mason

George Mason (December 11, 1725 – October 7, 1792) was a Founding Father of the United States. A delegate to the Constitutional Convention of 1787, he was one of three delegates who refused to sign the Constitution. His writings have exercised a significant influence on American political thought and events. The Virginia Declaration of Rights, which Mason principally authored, served as a basis for the United States Bill of Rights, of which he has been deemed a father. Many clauses in the Constitution were influenced by Mason's input, but he ultimately did not sign, citing the lack of a bill of rights. His prominent fight for a bill of rights led fellow Virginian James Madison to introduce one during the First Congress in 1789; these amendments were ratified in 1791, a year before Mason died. Obscure after his death, Mason later came to be recognized in the 20th and 21st centuries for his contributions to Virginia and the early United States. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
