Philosophical nihilism is the belief that life has no inherent meaning or value. This philosophy is rooted in the idea that the universe is ultimately meaningless or purposeless, and that human existence and consciousness are ultimately insignificant in the grand scheme of things.

Nihilism is often associated with skepticism and a rejection of traditional moral and religious beliefs. Nihilists may argue that the concept of meaning or value is a human construct, and that there is no objective basis for morality or purpose in the universe. As a result, they may reject traditional systems of ethics and morality, and may reject the idea of an ultimate moral authority or higher power.

While nihilism is often seen as a bleak and pessimistic philosophy, some nihilists may embrace it as a way of freeing themselves from the constraints of traditional beliefs and moral systems. They may see nihilism as a way of rejecting the illusion of meaning and pursuing their own individual goals and desires without being bound by conventional notions of right and wrong.
