While opposition to the state is central to anarchist thought, defining anarchism is not an easy task as there is a lot of discussion among scholars and anarchists on the matter and various currents perceive anarchism slightly differently. Hence, it might be true to say that anarchism is a cluster of political philosophies opposing authority and hierarchical organisation (including capitalism, nationalism, the state and all associated institutions) in the conduct of all human relations in favour of a society based on decentralisation, freedom and voluntary association. However, this definition has the same shortcomings as the definition based on anti-authoritarianism (which is an "a posteriori" conclusion), anti-statism (anarchism is much more than that) and etymology (which is simply a negation of a ruler). Nonetheless, major elements of the definition of anarchism include the will for a non-coercive society, the rejection of the state apparatus, the belief that human nature allows humans to exist in or progress toward such a non-coercive society and a suggestion on how to act to pursue the ideal of anarchy.
