Marilyn Ferguson was an American author, editor and public speaker known for her 1980 book The Aquarian Conspiracy, which is connected with the New Age Movement.

The Human Potential Movement (HPM) arose out of the counterculture of the 1960s and formed around the concept of an extraordinary potential that its advocates believed to lie largely untapped in all people. The movement takes as its premise the belief that through the development of their "human potential", people can experience a life of happiness, creativity, and fulfillment, and that such people will direct their actions within society toward assisting others to release their potential. Adherents believe that the collective effect of individuals cultivating their own potential will be positive change in society at large.
