A wonderful model of love and freedom!
Lisa Appignanesi looks at how the French philosophers remained committed to their open relationship – for more than 50 years.
In 1929, the French philosophers Jean-Paul Sartre and Simone de Beauvoir agreed to commit to an open relationship: one that lasted until Sartre’s death in 1980.
“De Beauvoir had declared that whatever her many books and literary prizes, whatever her role in the women’s movement, her greatest achievement in life was her relationship with Sartre,” says the author Lisa Appignanesi in this film.
She looks at how the writers and thinkers collaborated throughout their careers – and remained independent while continuing their conversation over decades.
