Imagine you’re handed a beautifully detailed map of life—then someone tells you the map might be wrong. Kierkegaard and Nietzsche are the two thinkers who first made that unsettling feeling into philosophy.
KIERKEGAARD: THE DRAMA OF CHOOSING YOURSELF
Søren Kierkegaard (19th-century Denmark) thought the most important truths aren’t just “known”—they’re lived. He aimed at the comfortable Christianity of his day, where faith looked like polite social membership rather than a risky personal commitment. For him, the central question is not “What is true?” but “How do I exist in relation to truth?”
Kierkegaard’s famous idea is the “leap of faith”: not a leap into irrationality, but a leap beyond what reason can guarantee. Some life decisions—loving someone, committing to a vocation, trusting a moral path—cannot be proven like a theorem. You choose anyway, and that choice reveals who you are.
“Subjectivity is truth.”
— Søren Kierkegaard (often paraphrased from his journals and pseudonymous works)
He introduces the idea that anxiety and uncertainty aren’t bugs in human life—they’re features of freedom. If you must choose without guarantees, your inner life becomes philosophically central.
NIETZSCHE: AFTER “GOD IS DEAD,” NOW WHAT?
Friedrich Nietzsche (19th-century Germany) delivers a different shock: “God is dead” doesn’t mean a deity literally expired—it means the old shared sources of meaning and morality (especially Christian frameworks) were losing cultural authority. The problem isn’t atheism; it’s the vacuum left behind. If traditional values no longer feel binding, what keeps life from sliding into nihilism—“nothing matters”?
Nietzsche’s challenge is creative: instead of clinging to inherited rules or collapsing into cynicism, we must become value-makers. He praises “self-overcoming”—treating your character like a craft project, not a fixed identity. Think of it like upgrading an operating system: you don’t just delete old code; you write better code to run a richer life.
“He who has a why to live can bear almost any how.”
— Friedrich Nietzsche (from 'Twilight of the Idols', echoing earlier formulations)
Nietzsche isn’t simply saying “anything goes.” He attacks herd morality and shallow comfort, but he also demands discipline, honesty, and responsibility in creating values—more like an artist’s rigor than a rebel’s tantrum.
- Meaning is forged through personal commitment under uncertainty
- Anxiety signals freedom and responsibility
- The individual stands before God (or ultimate accountability)
- Meaning is made after old certainties collapse
- Nihilism is the danger; self-overcoming is the response
- The individual must author values without leaning on tradition
THE BRIDGE TO EXISTENTIALISM
Put them together and you get a preview of existentialism’s core mood: you are not merely a spectator of life—you are responsible for it. Kierkegaard teaches that existence involves choices that cannot be outsourced to formulas. Nietzsche insists that when inherited meaning weakens, adulthood begins: you must create, not just obey.
Pick one area where you’ve been “following the script” (career, relationships, beliefs). Ask: Is this my commitment (Kierkegaard) or just inherited habit? Then ask: If I had to justify this value from scratch, what would I build (Nietzsche)?
- Kierkegaard centers lived experience: the self is formed through choices made without certainty.
- The “leap of faith” highlights commitment beyond proof, where anxiety often accompanies freedom.
- Nietzsche’s “God is dead” names a cultural crisis of meaning, not a literal event.
- Nietzsche’s answer to nihilism is value-creation and self-overcoming, not moral chaos.
- Together, they prepare you for existentialism’s big theme: you are responsible for making a life that can stand up to your own scrutiny.
