Libertarianism refers to the group of political philosophies which emphasize freedom, liberty, and voluntary association. There is no general consensus among scholars on the precise definition. Libertarians generally advocate a society with a government of small scope relative to most present day societies or no government whatsoever.

The Stanford Encyclopedia of Philosophy defines libertarianism as the moral view that agents initially fully own themselves and have certain moral powers to acquire property rights in external things. Libertarian historian George Woodcock defines libertarianism as the philosophy that fundamentally doubts authority and advocates transforming society by reform or revolution. Libertarian philosopher Roderick Long defines libertarianism as "any political position that advocates a radical redistribution of power from the coercive state to voluntary associations of free individuals", whether "voluntary association" takes the form of the free market or of communal co-operatives. According to the U.S. Libertarian Party, libertarianism is the advocacy of a government that is funded voluntarily and limited to protecting individuals from coercion and violence.

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.

Charles Peete "Charlie" Rose, Jr. (born January 5, 1942) is an American television talk show host and journalist. Since 1991 he has hosted Charlie Rose, an interview show distributed nationally by PBS since 1993. He has also co-anchored CBS This Morning since January 2012. Rose, along with Lara Logan, has hosted the revived CBS classic Person to Person, a news program during which celebrities are interviewed in their homes, originally hosted from 1953 to 1961 by Edward R. Murrow.

Rose was born in Henderson, North Carolina, the only child of Margaret Frazier and Charles Peete Rose, Sr., tobacco farmers who owned a country store. As a child, Rose lived above his parents' store in Henderson and helped out with the family business from age seven. Rose admitted in a Fresh Dialogues interview that as a child his insatiable curiosity was constantly getting him in trouble. A high school basketball star, Rose entered Duke University intending to pursue a degree with a pre-med track, but an internship in the office of Democratic North Carolina Senator B. Everett Jordan got him interested in politics. Rose graduated in 1964 with a bachelor's degree in history. At Duke, he was a member of the Kappa Alpha Order fraternity. He earned a Juris Doctor from the Duke University School of Law in 1968. He met his wife, Mary (née King), while attending Duke.

Penn Fraser Jillette (born March 5, 1955) is an American illusionist, comedian, musician, and best-selling author known for his work with fellow magician Teller in the team Penn & Teller, and advocacy of atheism, scientific skepticism, libertarianism and free market capitalism.

Jillette was born in Greenfield, Massachusetts. His mother, Valda R. Jillette (née Parks) (November 8, 1909 – January 1, 2000), was a secretary, and his father, Samuel H. Jillette (March 14, 1912 – February 14, 1999), worked at Greenfield's Franklin County Jail. Jillette became disenchanted with traditional illusionist acts that presented the craft as authentic magic, such as The Amazing Kreskin on The Tonight Show Starring Johnny Carson. At age eighteen, he saw a show by illusionist James Randi, and became enamored of his approach to magic that openly acknowledged deception as entertainment rather than a mysterious supernatural power. Jillette regularly acknowledges Randi as the one person on the planet he loves the most besides members of his family.

Ralph Nader ( /ˈneɪdər/; born February 27, 1934) is an American political activist, as well as an author, lecturer, and attorney. Areas of particular concern to Nader include consumer protection, humanitarianism, environmentalism, and democratic government.

Nader came to prominence in 1965 with the publication of his book Unsafe at Any Speed, a critique of the safety record of American automobile manufacturers in general, and most famously the Chevrolet Corvair. In 1999, an NYU panel of journalists ranked Unsafe at Any Speed 38th among the top 100 pieces of journalism of the 20th century.

Nader is a six-time candidate for President of the United States, having run as a write-in candidate in the 1992 New Hampshire Democratic primary, as the Green Party nominee in 1996 and 2000, and as an independent candidate in 2004 and 2008. Some people claim that Nader acted as a spoiler in the 2000 U.S. presidential election, while others, including Nader, dispute this claim.

Nader was born in Winsted, Connecticut. His parents, Nathra and Rose (née Bouziane) Nader, were immigrants from Lebanon and members of the Maronite Church. His family's native language is Arabic, and he has spoken it along with English since childhood. His sister, Laura Nader, is an anthropologist. His father worked in a textile mill and later owned a bakery and restaurant where he talked politics with his customers.
