Direct Realism

Direct Realism

When you perceive the world, you perceive real, mind-independent objects directly, just as they are.

Argument from Illusion

Perceptual situations where an object appears different from how it really is (e.g. a straight pencil looks bent in water), suggesting we do not perceive objects exactly as they are.

Direct Realist response to illusion

The object has a relational property in those conditions (e.g. bent-looking in water), so the perception is still of the real object.

Argument from Perceptual Variation

The same object can appear different depending on lighting, angle, distance, or observer, suggesting perception may not reveal the object’s real properties.

Direct Realist response to perceptual variation

The object has a relational property in those conditions (e.g. lighting, angle), so the perception is still of the real object.

The argument from hallucination

You can perceive things that are not there at all and hallucinations feel the same to real perception.

Direct Realist response to hallucination

Veridical perception and hallucination are fundamentally different mental states. The fact they are indistinguishable is just a psychological limitation, not proof they are identical.

Time-Lag Argument

Because light and sound take time to reach us, we perceive objects as they were in the past, not how they are now (e.g. seeing the sun as it was 8 minutes ago).

Direct Realist response to time-lag

Causal delay does not introduce a mental intermediary, so perception can still be direct. Just because you see it as it was 8 minutes ago, doesn't mean it is not direct perception.
