Existentialism emphasizes the inherent freedom of the individual to choose their own path and create their own meaning in life.

Existentialists argue that society often imposes arbitrary rules and expectations on the individual, which can stifle their freedom and authenticity.

Existentialists believe that the individual is constantly struggling to assert their freedom and authenticity in a society that often tries to suppress them.

Existentialists believe that authenticity is achieved when the individual lives in accordance with their true self, rather than conforming to external expectations.

Existentialists believe that responsibility is not something that is forced upon the individual, but rather a choice that they make in order to live a meaningful and authentic life.

Existentialists believe that life has no inherent meaning, and that it is up to the individual to create their own meaning through their choices and actions.

Existentialists believe that alienation is a result of the individual's estrangement from their true self, from others, and from the world around them, which is often caused by social and economic conditions.

Existentialists believe that the individual should not simply conform to society or rebel against it, but rather engage with it in a critical and transformative way, in order to create a more just and authentic world.
