Being
Being is the oldest question philosophy has ever asked and the hardest one it can still not quite leave alone: if nothingness is always imaginable, why does anything exist at all?

The World That Made It

Timeline
Parmenides composes the poem later called On Nature
**500 BC** — In the surviving fragments of the poem, Parmenides distinguishes the way of truth from the way of opinion and makes the claim that what is cannot come from what is not. The work forces Greek philosophy to confront the problem of nonbeing as a threat to thought itself.
Plato writes the Sophist
**380 BC** — Plato’s dialogue confronts the difficulty of speaking about falsehood, difference, and nonbeing without collapsing logic into contradiction. The text becomes a lasting resource for later reflections on what it means for something to be and not be.
Aristotle develops the doctrine that being is said in many ways
**340 BC** — In the Metaphysics, Aristotle rejects the idea that being is a single genus and instead analyzes substance, actuality, potentiality, and causation. This becomes one of the most durable classical frameworks for thinking about existence.
Thomas Aquinas synthesizes being and creation
**1270** — In medieval scholastic philosophy, being is increasingly understood through the lens of contingency and divine creation. Aquinas’s treatment of esse deepens the link between existence and dependence, giving the problem of why there is something rather than nothing a theological shape.
Kant publishes the Critique of Pure Reason
**1781** — Kant argues that existence is not a real predicate and limits speculative reason’s ability to answer metaphysical questions about the absolute. His critique reshapes the terrain on which later ontology must operate.
Martin Heidegger is born
**1889** — Heidegger’s later work will transform the question of being by tying it to temporality, worldhood, and human existence. His philosophical trajectory begins in a Germany where phenomenology, theology, and neo-Kantianism are all in play.
Being and Time appears
**1927** — Heidegger’s major early work introduces Dasein, being-in-the-world, care, and the ontological difference. It becomes one of the most consequential philosophical books of the twentieth century.
What Is Metaphysics? is delivered
**1929** — Heidegger’s lecture radicalizes the relation between being and nothingness by claiming that the nothing is disclosed in anxiety. The text intensifies both the originality and the controversy of his ontological project.
Heidegger becomes rector of Freiburg University
**1933** — His public association with National Socialism becomes one of the most disputed episodes in modern philosophy. Later readers have struggled to determine how far the political turn is connected to his ontology and historical thinking.
The Question Concerning Technology is developed
**1949** — Heidegger’s critique of technology reframes modern life as a mode of revealing in which beings are ordered as standing-reserve. The essay extends ontology into a diagnosis of modern civilization.
Sartre publishes Being and Nothingness
**1943** — Sartre adapts and contests Heidegger’s vocabulary, making negation, freedom, and self-deception central to existential analysis. The book helps popularize the philosophical drama of being and nothingness beyond specialist circles.
Derrida’s early Heideggerian engagements deepen the critique of presence
**1970** — Across his work, Derrida extends Heidegger’s challenge to metaphysics by showing how presence depends on difference, trace, and deferral. This becomes one of the most influential reinterpretations of being in late twentieth-century theory.
