Intentionality
• Mental states are ‘about’, or ‘directed onto’, something, e.g. belief about Paris, desire for chocolate.
• Intentionality has nothing to do with intentions.
• An Intentional mental state has Intentional content.

Intentional content
• Oedipus kills his father out of anger– Was Oedipus angry with his father? Yes, and no
• We always think of the world in a particular way– Do atmospherically formed crystals in
hexagonal form reflect all wavelengths of visible light?
– Call this ‘aspectual shape’.
• Intentional object: the thing we think about• Intentional content: object + shape

Reduction
• How can anything physical have Intentionality?– Physical states and properties, e.g. chemical
ones, are never ‘about’ anything
• Functionalism: Intentionality is a causal-functional property– A belief is about dogs because it is caused by
dogs and causes behaviour towards dogs.– But a cloud is caused by water evaporating from
the sea; yet the cloud isn’t about the sea.

Functional accounts
• Beliefs carry information about the world.– Natural states do this, e.g. smoke carries
information about fire.
• But beliefs can be mistaken, smoke cannot.• The function of beliefs is to represent the
world truly.– Many natural things can malfunction.– Mistake = malfunction
• Stomachs can malfunction, but still aren’t ‘about’ food.

The Chinese Room
• Is artificial intelligence intelligent? Searle: only if Intentionality could be reduced to functions

One response
• The issue is the type of interaction with the world:– Replace the person by a computer.– Put the computer inside a robot.– Connect up a visual input and audio
output.– The robot can now ‘name’ objects in
Chinese.– Does the robot understand Chinese?

Consciousness and aspect
• Searle: the robot still doesn’t understand, but ‘simulates’ understanding
• To understand, we need consciousness– Aspectual shape is essential to genuine
Intentionality– Only consciousness provides aspectual
shape (point of view)
