Kierkegaardian idea:
The leap of faith is probably Kierkegaard's most famous idea the notion that certain commitments (religious faith, romantic love, ethical conviction) cannot be reached through reason alone. At some point, you must simply choose to believe or commit, jumping across a gap that logic cannot bridge.
This connects to his concept of the three stages of existence:
the aesthetic (living for pleasure and novelty), the ethical (living by duty and universal principles), and the religious (living in direct relationship with God). You can't reason your way from one stage to the next each transition requires a qualitative leap.
Kierkegaard also emphasized subjective truth, the idea that what matters isn't just whether something is objectively true, but whether you relate to it with passion and personal commitment. "Truth is subjectivity" didn't mean truth is whatever you want; it meant that existential truths must be lived, not merely known.
His critique of the crowd is remarkably modern:
he argued that losing yourself in mass opinion, public consensus, or institutional religion lets you evade the anxiety of genuine individual choice. Authentic existence requires standing alone before your decisions.
Finally, there's his treatment of anxiety (or dread) as the dizziness of freedom the vertigo we feel when confronting our own radical openness to possibility. Unlike fear, which has a specific object, anxiety arises from freedom itself.
