nihilism

Nihilism is a way of thinking that says that nothing really matters in life. It can mean different things for different people, but many people who believe in nihilism think that life can be meaningless and that nothing we do really matters. They might believe that life has no purpose and is all just an accident, or that morality and ethics don't really exist. In a nutshell, nihilism is the idea that nothing really matters and that life has no greater meaning.
