"There is a good principle that created order, light and man; and a
bad principle that created chaos, darkness and woman."
Pythagoras (circa 582-507 B.C.)

(In Simone de Beauvoir, The Second Sex, 1949/2010).
Gender Inequality has existed ever since human history has been written. Pythagoras has given a moral definition of being male and female that has set humanity and its civilizations on a collision course with the extinction of Homo sapiens. No species on this planet is as violent toward its females and her offspring than Homo sapiens.

There is not a theistic religion on this planet that has affirmed the full equality of the feminine

with the masculine, which has set in stone the perpetration of violence against women and her children. Prescott (1989,1995ab) has reviewed this history in essays:

Genital Pain vs. Genital Pleasure: Why The One and Not The Other? “Violence Against Women: Philosophical and Religious Foundations of Gender Morality”; “OPINION: The challenge: achieve gender equality”; and “A Proposed “Bodily Sovereignty” Amendment To The U.S. Constitution”.

Simone de Beauvoir?s The Second Sex originally published in France (1949) and recently reprinted in a new translation by Alfred A. Knopf (2010) is considered the authoritative translation of her work and the leading intellectual document of the feminist cultural movement. It is the foundation for restoring full equality between man and woman that was lost with the passing of the hunter-gathers some 8,000-10,000 years ago.

A few quotations The Second Sex:

“What is a woman?” (p.5).

“The female is female by virtue of a certain lack of qualities”, Aristotle said. “We should regard women’s nature as suffering from natural defectiveness.” And Saint Thomas in his turn decreed that woman was an “incomplete man,” an “incidental” being” (p.5).

“Humanity is male, and man defines woman not in herself, but in relation to himself; she is not considered an autonomous being. (p.5).

“He is the Subject, he is the Absolute. She is the Other.3 “ (p.6)

“Why do women not contest male sovereignty?” (p.7)
