Existentialism profoundly affected society by providing a new way of thinking that encouraged people to explore their individual identities and to question the world around them. By promoting free thought and free expression, existentialism helped to liberate individuals from traditional societal norms and expectations.
Existentialism also had a significant impact on mental health by helping people to explore their innermost thoughts and feelings. By opening up dialogue about mental health, existentialists hoped to help people cope with their challenges in a healthy way.
