Self vs non-self (Philosophy HL)

The big idea: You draw a line every day without noticing: on one side is you, on the other is everything that isn't you — the room, the street, and other people.

But push on it. Is that line something you find already there, or something you draw? And does the way you draw it help make the 'you' inside it?

This micro is about the boundary between self and non-self. The surprise ahead: the two thinkers here argue that other people are what draw the line — and so partly make the self.

Start with a moment you've almost certainly lived through.

Sartre: 'the Look': Jean-Paul Sartre describes peeping through a keyhole, completely lost in what you're watching — no 'self' in your mind, just the scene. Then footsteps: someone is behind you. In a rush you feel yourself become a thing that can be seen — a nosy person, caught. That jolt is what Sartre calls the Look. Before the Other looked, there was no 'you' in the picture; their gaze puts one there.

Checkpoint — Sartre: In one line: you become aware of yourself as a self when the Other looks at you. Hold that — the next thinker says the Other doesn't just make you self-aware, they make you a self at all.

An earlier thinker pushes the point harder: it isn't just being looked at, it's being acknowledged.

Hegel: self-consciousness needs recognition: Georg Wilhelm Friedrich Hegel argued that to be a full self-consciousness, you need another self-consciousness to recognise you — to treat you as a someone, not a something. Think how differently you feel when a person greets you as an equal versus looks straight through you. For Hegel, a self only comes fully alive when another self says, in effect, 'I see you as a self too.'

Go further — higher-level insight: Spot the shared claim, and the difference. Both Hegel and Sartre agree the self needs the Other. But Hegel is warmer — recognition can be mutual, two selves lifting each other. Sartre is edgier — the Look can feel like being pinned down as an object. Naming that split (recognition-as-gift vs gaze-as-trap) is a top-band move.

Checkpoint — Hegel: In one line: a self needs to be recognised by another self to fully become one. So both thinkers move the self OUTWARD — you find yourself in the eyes of others.
