Existentialist Philosophy

Søren Kierkegaard

1813–1855 · Existentialist Philosophy


The Philosopher of the Leap

Kierkegaard is for the person who knows that the most important decisions in life cannot be made by reasoning alone — and that this terrifies you. You've probably experienced the paralysis of a choice that no amount of analysis can resolve: not because you lack information, but because the choice is about who you want to become. Kierkegaard named this "anxiety" — the dizziness of freedom — and spent his life exploring what it means to exist as a singular individual who must choose without guarantees.

Where to Start Reading

Either/Or (abridged, trans. Alastair Hannay)

Kierkegaard's most famous work — two competing philosophies of life presented as manuscripts found in a desk. The Penguin abridged edition is the way in. 'The Seducer's Diary' in Part One and Judge Wilhelm's letters in Part Two are the essential sections.

The Concept of Anxiety

Short, dense, and the source of existentialism's central idea: anxiety as the experience of freedom. Not easy, but the payoff — understanding why possibility itself can be terrifying — is immense.

Fear and Trembling

Kierkegaard retells Abraham and Isaac to explore what it means to make a commitment beyond reason. The 'leap of faith' originates here. Short and electrifying — his most accessible philosophical work.

“Anxiety is the dizziness of freedom.”
