Anti-capitalist in the context of "Biocentrism (ethics)"

Anarchism is a political philosophy and movement that seeks to abolish all institutions that perpetuate authority, coercion, or hierarchy, primarily targeting the state and capitalism. Anarchism advocates for the replacement of the state with stateless societies and voluntary free associations. A historically left-wing movement, anarchism is usually described as the libertarian wing of the socialist movement (libertarian socialism).

Although traces of anarchist ideas are found all throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose conclusion marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more, growing in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements.

In the United States, libertarianism is a political philosophy promoting individual liberty. Libertarianism has been described as laissez-faire on economic issues while supporting civil liberties and personal freedom. The movement is often associated with a foreign policy of non-interventionism. Broadly, there are four principal traditions within libertarianism, namely the libertarianism that developed in the mid-20th century out of the revival tradition of classical liberalism in the United States after liberalism associated with the New Deal; the libertarianism developed in the 1950s by anarcho-capitalist author Murray Rothbard, who based it on the anti-New Deal Old Right and 19th-century libertarianism and American individualist anarchists such as Benjamin Tucker and Lysander Spooner while rejecting the labor theory of value in favor of Austrian School economics and the subjective theory of value; the libertarianism developed in the 1970s by Robert Nozick and founded in American and European classical liberal traditions; and the libertarianism associated with the Libertarian Party, which was founded in 1971, including politicians such as David Nolan and Ron Paul.

The right-libertarianism associated with people such as Murray Rothbard and Robert Nozick, whose book Anarchy, State, and Utopia received significant attention in academia according to David Lewis Schaefer, is the dominant form of libertarianism in the United States, compared to that of left-libertarianism. The latter is associated with the left-wing of the modern libertarian movement and more recently to the political positions associated with academic philosophers Hillel Steiner, Philippe Van Parijs and Peter Vallentyne that combine self-ownership with an egalitarian approach to natural resources; it is also related to anti-capitalist, free-market anarchist strands such as left-wing market anarchism, referred to as market-oriented left-libertarianism to distinguish itself from other forms of libertarianism.

Murray Bookchin (/ˈbʊktʃɪn/; January 14, 1921 – July 30, 2006) was an American social theorist, author, orator, historian, and political philosopher. Influenced by G. W. F. Hegel, Karl Marx, and Peter Kropotkin, he was a pioneer in the environmental movement. Bookchin formulated and developed the theory of social ecology and urban planning within anarchist, libertarian socialist, and ecological thought. He was the author of two dozen books covering topics in politics, philosophy, history, urban affairs, and social ecology. Among the most important were Our Synthetic Environment (1962), Post-Scarcity Anarchism (1971), The Ecology of Freedom (1982), and Urbanization Without Cities (1987). In the late 1990s, he became disenchanted with what he saw as an increasingly apolitical "lifestylism" of the contemporary anarchist movement, stopped referring to himself as an anarchist, and founded his own libertarian socialist ideology called "communalism", which seeks to reconcile and expand Marxist, syndicalist, and anarchist thought.

Bookchin was a prominent anti-capitalist, anti-fascist and advocate of social decentralization along ecological and democratic lines. His ideas have influenced social movements since the 1960s, including the New Left, the anti-nuclear movement, the anti-globalization movement, Occupy Wall Street, and the democratic confederalism of the Democratic Autonomous Administration of North and East Syria. He was a central figure in the American green movement. An autodidact who never attended college, he is considered to be one of the most important left theorists of the twentieth century.
