# Philosophy 101: Heidegger - Being and Time

## The Question of Being

Martin Heidegger (1889–1976) is controversial (due to his Nazi party membership), but his philosophy changed the 20th century.

He realized we had forgotten the most basic question: **What does it mean *to be*?**

## [Dasein](/vocab/dasein)

He didn't like the word "Human" or "Subject." He used **Dasein** (Being-there).

We are not isolated minds looking at a world. We are *thrown* into a world that already has meaning.

* **Ready-to-hand:** We use tools (like a hammer) without thinking about them. They are extensions of us.

* **Present-at-hand:** Only when the hammer *breaks* do we look at it as an object ("just a hammer").

## Authenticity vs. The "They"

Most of us live in "inauthenticity." We do what "They" (Das Man) do. We talk about what "They" talk about.

To be authentic is to face our own finitude (Death). We are "Being-towards-death." Realizing we will die snaps us out of the trance of the "They" and forces us to choose our own life.

## Why He Matters

He dismantled the Descartes "Subject/Object" split. He influenced Sartre, Derrida, Foucault, and basically all of postmodernism.

Next, the man who tried to solve philosophy just by looking at words: **Wittgenstein**.

# Philosophy 101: Wittgenstein - The Fly in the Fly-Bottle

## The Man Who Solved Philosophy (Twice)

Ludwig Wittgenstein (1889–1951) was an Austrian genius who treated philosophy like a disease.

## Early Wittgenstein: The Picture Theory

In his first book, *Tractatus Logico-Philosophicus*, he argued that language creates "pictures" of the world.

* "Whereof one cannot speak, thereof one must be silent."

* He thought he solved everything: Philosophy is just clearing up logical confusions. So he quit philosophy and became a gardener.

## Later Wittgenstein: [Language Games](/vocab/language-games)

He realized he was wrong. He came back and wrote *Philosophical Investigations*.

He argued that meaning isn't about "labeling" objects. **Meaning is Use.**

* **Language Games:** Language is a set of activities. "Water!" means something different if you are ordering at a cafe vs. warning someone about a flood.

* **The Beetle in the Box:** If we all have a box with a "beetle" inside, but no one can see anyone else's, the word "beetle" doesn't refer to the thing itself, but to its use in our public game.

## The Fly-Bottle

His goal: "To show the fly the way out of the fly-bottle."

Philosophy is the fly buzzing around, confused by the glass. Wittgenstein wanted to uncork the bottle so we could stop doing metaphysics and just... be.

## Graduation (Again)

You've met the giants.

From Socrates questioning the street corner to Wittgenstein analyzing the words we use to ask the questions.

The point wasn't to memorize their names. It was to see that reality is weirder, deeper, and more malleable than it looks.

Go touch grass. (Phenomenologically, of course).

<strong className="text-current">Solipsism</strong> is the philosophical idea that only one's own mind is sure to exist.
