Existentialism

Disciplines:
philosophy

Summary

The philosophical tradition holding that existence precedes essence — there is no fixed human nature, individuals are radically free and responsible for creating themselves and their values.

Core Contribution

Sartre's formula: 'existence precedes essence' — unlike manufactured objects (whose essence precedes existence), humans exist first and define themselves through choices. Radical freedom: humans are 'condemned to be free' — they cannot escape choice or responsibility. Bad faith: the self-deception by which individuals deny their freedom and pretend they are determined by their nature or role. Heidegger's Dasein: being-in-the-world as the fundamental human condition; authenticity vs. das Man (conformity to the crowd). Kierkegaard's leap: existence before system, subjectivity as truth.

Key Spikes & Highlights

  • Sartre's existentialism generates an absolute responsibility that most people find psychologically unbearable: since there is no human nature and no God to determine what we should be, we are entirely responsible for what we are — including the circumstances we 'find' ourselves in.
  • The tension between Sartre's existentialism (radical freedom) and Heidegger's (facticity, thrownness, the weight of history) is one of the central fault lines within existentialism itself.
