Existentialist philosophy, a philosophy that developed in the 19th-20th century period, emphasizes personal liberty, choice, and individual experience. At the heart of this philosophy is the idea that existence precedes essence, indicating that humans determine their own meaning 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 seemingly indifferent universe.

This school of thought confronts conventional ideas of preordained fate and the idea that life's purpose is pre-established. Instead, existentialism suggests that people must confront the fundamental skincare philosophy absurdity of life and embrace their liberty to decide and do. This often leads to an existential dilemma, where persons wrestle with feelings of unease and bewilderment as they encounter the void of intrinsic meaning. Nevertheless, it is through this conflict that one can achieve authentic existence by acknowledging liability for one's actions and creating personal significance.

Existentialism also explores ideas of estrangement, despair, and the human condition. In a society where conventional beliefs and values are often scrutinized, existentialist thought provides a foundation for understanding the complexities of human existence. By acknowledging the lack of universal truths, existentialist thought urges persons to thrive vividly and truly, despite the ambiguities and obstacles of life. It is a appeal to welcome the autonomy and accountability that come with being a person, and to seek purpose in an otherwise uncaring universe.
