Existentialist philosophy, a ideology that arose in the 19th and 20th centuries, stresses individual autonomy, decision-making, and subjective experience. At the heart of this philosophy is the notion that existence comes before essence, meaning that individuals define their own purpose and goals through their actions. Philosophers of existentialism like Jean-Paul Sartre and Friedrich Nietzsche argue that life is inherently meaningless, and it is up to each person to forge their own beliefs in a apparently indifferent cosmos.

This philosophy questions traditional notions of predetermination and the notion that life's meaning is predetermined. Conversely, existentialism proposes that individuals must acknowledge the inherent irrationality of life and welcome their freedom to make choices and take action. This often causes an existential crisis, where people wrestle with feelings of unease and confusion as they encounter the lack of inherent meaning. Nonetheless, it is through this dilemma that one can reach authentic existence by accepting accountability for one's decisions and forging personal importance.

By acknowledging the absence of absolute truths, existentialist philosophy urges people to exist vividly and genuinely, despite the doubts and difficulties of life. It is a invitation to accept the liberty and accountability that come with being a person, and to seek purpose in an otherwise uncaring world.
