Question: Which 1916 French document reinforces the belief that self-governed societies should be based on voluntary institutions?

Context paragraphs:
Manifesto of the Sixteen: The Manifesto of the Sixteen (French: "Manifeste des seize" ), or Proclamation of the Sixteen, was a document drafted in 1916 by eminent anarchists Peter Kropotkin and Jean Grave which advocated an Allied victory over Germany and the Central Powers during the First World War.  At the outbreak of the war, Kropotkin and other anarchist supporters of the Allied cause advocated their position in the pages of the "Freedom" newspaper, provoking sharply critical responses.  As the war continued, anarchists across Europe campaigned in anti-war movements and wrote denunciations of the war in pamphlets and statements, including one February 1916 statement signed by prominent anarchists such as Emma Goldman and Rudolf Rocker.

Redstone Old Fort: Redstone Old Fort — or Redstone Fort or (for a short time when built) Fort Burd — on the Nemacolin Trail, was the name of the French and Indian War-era wooden fort built in 1759 by Virginia militia colonel James Burd to guard the ancient Indian trail's river ford on a mound overlooking the eastern shore of the Monongahela River (colloquially, just "the Mon") in what is now Fayette County, Pennsylvania near, or (more likely) on the banks of Dunlap's Creek at the confluence.  The site is unlikely to be the same as an earlier fort the French document as Hangard dated to 1754 and which was confusedly, likely located on the nearby stream called Redstone Creek.  Red sandstones predominate the deposited rock column of the entire region.

Anarchism: Anarchism is a political philosophy that advocates self-governed societies based on voluntary institutions.  These are often described as stateless societies, although several authors have defined them more specifically as institutions based on non-hierarchical free associations.  Anarchism holds the state to be undesirable, unnecessary and harmful.

History of anarchism: Anarchism is a political philosophy that advocates stateless societies often defined as self-governed voluntary institutions, but that several authors have defined as more specific institutions based on non-hierarchical free associations.  Anarchism holds the state to be undesirable, unnecessary, or harmful.  While anti-statism is central, anarchism entails opposing authority or hierarchical organisation in the conduct of human relations, including, but not limited to, the state system.

Spirit possession: Spirit possession is a term for the belief that animas, demons, extraterrestrials, gods, or spirits can take control of a human body.  The concept of spirit possession exists in many religions, including Christianity, Buddhism, Haitian Vodou, Wicca, Hinduism, Islam and Southeast Asian and African traditions.  In a 1969 study funded by the National Institute of Mental Health, spirit possession beliefs were found to exist in 74% of a sample of 488 societies in all parts of the world.  Depending on the cultural context in which it is found, possession may be considered voluntary or involuntary and may be considered to have beneficial or detrimental effects on the host.  Within possession cults, the belief that one is possessed by spirits is more common among women than men.

Conflict criminology: Largely based on the writings of Karl Marx, conflict criminology holds that crime in capitalist societies cannot be adequately understood without a recognition that such societies are dominated by a wealthy elite whose continuing dominance requires the economic exploitation of others, and that the ideas, institutions and practices of such societies are designed and managed in order to ensure that such groups remain marginalised, oppressed and vulnerable.  Members of marginalised and oppressed groups may sometimes turn to crime in order to gain the material wealth that apparently brings equality in capitalist societies, or simply in order to survive.  Conflict criminology derives its name from the fact that theorists within the area believe that there is no consensual social contract between state and citizen.
