A frog's visual system is triggered by a BB pellet falling in front of it, and the frog snaps. According to teleosemantics, what does the frog's visual state represent, and why?
AIt represents BB pellets, because that is what actually caused the state in this instance
BIt represents both flies and BB pellets, since both reliably trigger the same response
CIt represents flies, because the system evolved to track flies — that is its proper biological function
DIt represents nothing, because the state is a misfire and misrepresentation has no content
This is the core move of teleosemantics: content is fixed by evolutionary proper function, not by the actual or typical cause. The system was selected because it tracked flies and contributed to survival — that selective history defines what it is 'supposed' to detect. The BB pellet causes the same state but is not what the system was designed to track, which is exactly why snapping at a pellet is a misrepresentation — the state says 'fly here' when no fly is present. Option A gives the causal theory's answer, which teleosemantics is specifically designed to improve upon.
Question 2 Multiple Choice
Which problem in the philosophy of mind does teleosemantics solve that pure causal theories of content cannot solve?
AThe binding problem — how the brain integrates information from different sensory modalities
BThe problem of misrepresentation — explaining how a mental state can be about something that is not actually present or that is wrong
CThe hard problem of consciousness — explaining why physical processes give rise to subjective experience
DThe problem of other minds — determining whether other beings have mental states
Pure causal theories struggle with misrepresentation: if both flies and pellets cause the frog's snap-state, the state represents both — making 'misrepresentation' conceptually impossible (the state is always accurate to whatever caused it). Teleosemantics fixes content via proper function (what the system was selected to track), not causation, which allows misrepresentation: the state represents flies, and when a pellet causes it, the state is simply wrong. This is crucial because misrepresentation — false beliefs, perceptual illusions — is fundamental to how minds work.
Question 3 True / False
On the teleosemantic account, the content of a mental state is determined by the biological function the system was selected to perform, not merely by what normally or reliably causes the state.
TTrue
FFalse
Answer: True
This is the defining claim of teleosemantics. The distinction matters: a frog might come to live in an environment where BB pellets are more common than flies, so pellets 'normally' cause the snap-state in that environment. But on the teleosemantic account, the content is still 'fly' because the system's evolutionary history — what it was selected for — defines proper function, not the current distribution of causes. Proper function is historical and retrospective; it's about what the trait did that led to its being selected.
Question 4 True / False
If a frog's visual system reliably causes the same response to both flies and BB pellets, the teleosemantic account implies that the state represents both flies and BB pellets.
TTrue
FFalse
Answer: False
This is the pure causal theory's implication, not teleosemantics'. On the teleosemantic account, content is determined by what the system was *selected to track* — its proper biological function — not by what actually or reliably causes it. The frog's system was selected because of fly-detection; BB pellets may trigger the same state but were not part of the selective history. Therefore the state represents flies, and responses to pellets are misrepresentations, not an expansion of the state's content.
Question 5 Short Answer
Explain why teleosemantics can account for misrepresentation while pure causal theories of content struggle to do so.
Think about your answer, then reveal below.
Model answer: On a pure causal theory, a mental state represents whatever reliably causes it. If both flies and BB pellets cause the frog's snap-state, the state represents both — there is no error. Teleosemantics breaks this symmetry by grounding content in proper function: what the system was evolutionarily selected to track. The frog's system was selected for fly-detection, so the state represents flies regardless of what currently causes it. When a pellet triggers the state, the state is wrong — a misrepresentation — because its proper function is to respond to flies and the pellet is not a fly.
The key is that teleosemantics makes content normative: a state has a 'correct' cause (what it's supposed to be about) and can therefore be wrong. Pure causal theories are descriptive — they track what is, not what should be — and so cannot distinguish between a state being triggered correctly versus being triggered by something other than its content. The evolutionary/functional grounding gives teleosemantics a standard against which representational accuracy can be measured.
