Søren Kierkegaard, a Danish philosopher, is often credited as the father of Existentialism. His writings in the 19th century laid the foundation for the philosophical movement.

Existentialism primarily focuses on exploring the meaning of life and the significance of human existence. It delves into questions about the purpose and value of life.

Existentialism emphasizes the uncertainty and unpredictability of life. This uncertainty can lead to anxiety and a sense of meaninglessness.

Authenticity in Existentialism refers to being genuine and true to one's own values, beliefs, and desires, rather than conforming to external expectations or societal norms.

Jean-Paul Sartre, a prominent Existentialist philosopher, famously stated that 'Existence precedes essence.' This means that existence comes before essence, and that the meaning of life is not predetermined but rather created through one's actions and choices.

Existentialism emphasizes the importance of freedom, particularly the freedom to choose one's own destiny and create meaning in life. This freedom can be both empowering and daunting.

Existentialism stresses the significance of responsibility. It asserts that individuals are responsible for their choices and actions, and must accept the consequences of their decisions.

Albert Camus, a prominent Existentialist philosopher and writer, authored the novel 'The Stranger.' This novel explores themes of absurdity, alienation, and the search for meaning in life.

Existentialism acknowledges the inherent contradiction and absurdity of existence. It recognizes that human beings are finite and mortal, yet they strive for meaning and purpose in an often meaningless universe.

Friedrich Nietzsche, a German philosopher, famously declared 'God is dead.' This statement symbolizes the rejection of traditional religious beliefs and the emphasis on individual responsibility and self-creation.

In Existentialism, 'dasein' refers to the essence of human existence. It encompasses the unique and individual way in which humans experience and interpret the world.

Jean-Paul Sartre, a prominent Existentialist philosopher and playwright, wrote the play 'No Exit.' This play explores themes of freedom, responsibility, and the futility of human existence.

Existentialism emphasizes the importance of choice, particularly in the face of uncertainty and risk. It asserts that individuals must embrace their freedom to choose and create meaning in their lives.

Jean-Paul Sartre, a prominent Existentialist philosopher, famously stated 'Man is nothing else but what he makes of himself.' This quote highlights the idea that individuals are responsible for creating their own meaning and identity through their actions and choices.
