Nihilists

Nihilism (/ˈnaɪ.ᵻlɪzəm/ or /ˈniː.ᵻlɪzəm/; from the Latin nihil, nothing) is a philosophical doctrine that suggests the lack of belief in one or more reputedly meaningful aspects of life. Most commonly, nihilism is presented in the form of existential nihilism, which argues that life is without objective meaning, purpose, or intrinsic value.Moral nihilists assert that there is no inherent morality, and that accepted moral values are abstractly contrived. Nihilism may also take epistemological, ontological, or metaphysical forms, meaning respectively that, in some aspect, knowledge is not possible, or reality does not actually exist.

The term is sometimes used in association with anomie to explain the general mood of despair at a perceived pointlessness of existence that one may develop upon realising there are no necessary norms, rules, or laws. Movements such as Futurism and deconstruction, among others, have been identified by commentators as "nihilistic".
