Power is frequently defined by political scientists as the ability to influence the behavior of others with or without resistance. The term authority is often used for power perceived as legitimate by the social structure. Power can be seen as evil or unjust, but the exercise of power is accepted as endemic to humans as social beings. In the corporate environment, power is often expressed as upward or downward. With downward power, a company's superior influences subordinates. When a company exerts upward power, it is the subordinates who influence the decisions of the leader (Greiner & Schein, 1988). Often, the study of power in a society is referred to as politics.

The use of power need not involve coercion (force or the threat of force). At one extreme, it more closely resembles what everyday English-speakers call "influence", although some authors make a distinction between power and influence – the means by which power is used (Handy, C. 1993 Understanding Organisations).

Much of the recent sociological debate on power revolves around the issue of the enabling nature of power. A comprehensive account of power can be found in Steven Lukes Power: A Radical View where he discusses the three dimensions of power. Thus, power can be seen as various forms of constraint on human action, but also as that which makes action possible, although in a limited scope. Much of this debate is related to the works of the French philosopher Michel Foucault (1926–1984), who, following the Italian political philosopher Niccolò Machiavelli (1469–1527), sees power as "a complex strategic situation in a given society social setting". Being deeply structural, his concept involves both constraint and enablement. For a purely enabling (and voluntaristic) concept of power see the works of Anthony Giddens.

Alicia Augello Cook (born January 25, 1981), better known by her stage name Alicia Keys, is an American R&B singer-songwriter, record producer, and actress. Keys was raised by a single mother in the Hell's Kitchen area of Manhattan in New York City. At age seven, Keys began playing the piano. She attended Professional Performing Arts School and graduated at 16 as valedictorian. Keys released her debut album with J Records, having had previous record deals first with Columbia and then Arista Records.

Keys' debut album, Songs in A Minor, was a commercial success, selling over 12 million copies worldwide. She became the best-selling new artist and best-selling R&B artist of 2001. The album earned Keys five Grammy Awards in 2002, including Best New Artist and Song of the Year for "Fallin'". Her second studio album, The Diary of Alicia Keys, was released in 2003 and was also another success worldwide, selling eight million copies. The album garnered her an additional four Grammy Awards in 2005. Later that year, she released her first live album, Unplugged, which debuted at number one in the United States. She became the first female to have an MTV Unplugged album to debut at number one and the highest since Nirvana in 1994.

David Vaughan Icke (pronounced /aɪk/, or IKE, born 29 April 1952) is an English writer and public speaker, best known for his views on what he calls "who and what is really controlling the world." Describing himself as the most controversial speaker in the world, he is the author of 19 books and has attracted a global following that cuts across the political spectrum. His 533-page The Biggest Secret (1999) has been called "the Rosetta Stone for conspiracy junkies."

Icke was a well-known BBC television sports presenter and spokesman for the Green Party, when in 1990 a psychic told him he was a healer who had been placed on Earth for a purpose, and that the spirit world was going to pass messages to him so he could educate others. In March 1991 he held a press conference to announce that he was a "Son of the Godhead" – a phrase he said later the media had misunderstood – and the following month told the BBC's Terry Wogan show that the world would soon be devastated by tidal waves and earthquakes. He said the show changed his life, turning him from a respected household name into someone who was laughed at whenever he appeared in public.
