Nihilism is the philosophical doctrine suggesting the negation of one or more meaningful aspects of life. examples of Nihilism include:
- Existential Nihilism, which argues that life is without absolute meaning, purpose or intrinsic value.
- Moral Nihilism, which argues that nothing is Moral or Immoral. This can lead to Amoralism.
- Epistemological nihilism, which is considered extreme skepticism, in that all knowledge is denied.
- Metaphysical Nihilism, which is the philosophical theory that there might not be any objects at all.
- Mereological Nihilism (alternatively Compositional Nihilism), which is the position that objects with proper 'parts' do not exist, in space or time.
- Political Nihilism, a branch of Nihilism that follows the characteristic Nihilistic rejection of non-proven or non-rationalized assertions.
- Ontological Nihilism, the belief that absolutely nothing actually exists.
Christian Nihilism may include the belief that without God, there is no morality or ethics, absolute meaning or intrinsic value of life. Since God probably does not exist, this is de-facto Existential Nihilism. Friedrich Nietzsche frequently accused Christians of nihilism.
Some, but not all atheists are existential nihilists. Some are also moral nihilists. Other atheists reject both positions.
"What profit hath a man of all his labour which he taketh under the sun? [...] I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit. That which is crooked cannot be made straight: and that which is wanting cannot be numbered."
