 
 <prompt> Existentialism () na di work wey dey associated mainly with some late-19th- and 20th-century European philosophers wey, despite deep doctrinal differences, share di belief say philosophical thinking dey start with di human subject—not just di thinking subject, but di acting, feeling, living human individual. While di main value of existentialist thought dey commonly acknowledged to be freedom, di primary virtue na authenticity. For di view of di existentialist, di individual starting point dey characterized by wetin dem don call "di existential attitude", or a sense of disorientation, confusion, or dread in di face of an apparently meaningless or absurd world. Many existentialists also see traditional systematic or academic philosophies, in both style and content, as too abstract and far from concrete human experience.

Søren Kierkegaard na generally considered to be di first existentialist philosopher, even though e no use di term existentialism. E propose say each individual—not society or religion—is solely responsible for giving meaning to life and living am passionately and sincerely, or "authentically". Existentialism become popular for di years wey follow World War II, and e strongly influence many disciplines besides philosophy, including theology, drama, art, literature, and psychology.

Di term dey often seen as a historical convenience as e first apply to many philosophers in hindsight, long after dem don die. For fact, while existentialism generally considered to start with Kierkegaard, di first prominent existentialist philosopher wey adopt di term as a self-description na Jean-Paul Sartre. Sartre posit di idea say "wetin all existentialists get in common na di fundamental doctrine say existence dey come before essence", as scholar Frederick Copleston explain. According to philosopher Steven Crowell, defining existentialism don dey relatively difficult, and e argue say e better make we understand am as a general approach wey dem use to reject certain systematic philosophies instead of as a systematic philosophy itself. Sartre himself, for one lecture wey e deliver for 1945, describe existentialism as "di attempt to draw all di consequences from a position of consistent atheism". <response>: ```1. Søren Kierkegaard
