Card 1definition

Question

Direct realism?

Answer

The view that we perceive the real world directly, as it is — you see the mug itself, no middle step.

Card 2concept

Question

The argument from illusion?

Answer

Since appearances can differ from reality (a straight stick looks bent), what we see is an appearance, not the thing itself.

Card 3definition

Question

Representative realism?

Answer

A real world exists, but we only ever see the mental images it causes — like watching the world on a screen.

Card 4concept

Question

The 'screen' problem for representative realism?

Answer

If you only ever see the images, you can never step outside to check they match the real world.

Card 5concept

Question

Idealism (Berkeley)?

Answer

Reality is ultimately mental: only images, no material world behind them — 'to be is to be perceived'.

Card 6concept

Question

'To be is to be perceived'?

Berkeley's slogan: a thing exists as a bundle of experiences; unperceived, it needs God to keep existing.

Card 7process

The three theories on a scale?

Answer

Direct realism (see the world) → representative realism (see images of a world) → idealism (only images, no world behind).

Card 8comparison

The price each view pays (Go further)?

Answer

Direct: illusions. Representative: stuck behind the screen. Idealism: the world vanishes when unperceived (Berkeley uses God).
