A more thorough explanation:

Definition: Nihilism is a belief that there is no rational reason for moral principles and that there is no objective truth. It is also the view that traditional beliefs are baseless and that life is meaningless and useless. Additionally, it is a theory that the existing economic, social, or political institutions should be destroyed, regardless of the result, because of the basic undesirability of those institutions.

Examples:

• A person who believes in nihilism may think that there is no point in following any moral principles or values because they believe that there is no objective truth.
• Someone who is a nihilist may think that life is meaningless and that there is no purpose to it.
• A nihilist may also believe that the current economic, social, or political institutions are undesirable and should be destroyed, even if it means chaos or anarchy.

These examples illustrate how nihilism is a belief that rejects traditional values and institutions, and instead advocates for a complete destruction of them. It is a philosophy that can lead to a sense of hopelessness and despair, as it denies the existence of any objective meaning or purpose in life.
