Kierkegaard's philosophy shook up 19th-century thought by focusing on individual existence and subjective truth. He challenged Hegel's systematic approach, emphasizing personal responsibility and the limits of rational thinking in understanding human experience.

Kierkegaard's ideas on faith, anxiety, and authenticity laid the groundwork for existentialism. His use of pseudonyms and literary devices to explore philosophical concepts influenced later thinkers and writers, reshaping how we approach questions of meaning and existence.

Key Concepts in Kierkegaard's Philosophy

The Individual and Subjective Truth

• Kierkegaard's concept of the "individual" emphasizes personal responsibility and subjective truth over objective systems
• Three stages of existence represent different levels of self-awareness and commitment
  • Aesthetic stage focuses on immediate pleasure and avoidance of boredom
  • Ethical stage involves commitment to moral principles and societal norms
  • Religious stage represents the highest form of existence, characterized by a personal relationship with God
• Notion of "anxiety" stems from the freedom to choose and the burden of responsibility
  • Manifests as a feeling of dizziness or vertigo when confronted with infinite possibilities
  • Serves as a catalyst for personal growth and self-discovery
• Concept of "despair" understood as a misrelation of the self to itself and to the power that established it
  • Three forms of despair: unconscious, conscious but unwilling to change, and defiant despair
  • Can only be overcome through faith and acceptance of one's true self

Faith and Indirect Communication

• Emphasis on the "passion of faith" as a subjective, inward experience beyond rational argumentation
  • Involves a personal commitment to believe in the face of uncertainty and paradox
  • Exemplified by the biblical figure of Abraham in Kierkegaard's work "Fear and Trembling"
• Idea of "indirect communication" uses pseudonyms and literary devices to engage readers in self-reflection
  • Pseudonyms include Victor Eremita, Johannes de Silentio, and Anti-Climacus
