Philosophical Behaviourism

Students analyse hard and soft behaviourism, focusing on Hempel and Ryle. They will evaluate whether mental states can be entirely reduced to behavioural dispositions.

TL;DR:Philosophical Behaviourism is a physicalist theory that claims mental states are not 'inner' private events, but are instead reducible to outward behaviour or 'dispositions' to behave. Students study Hempel's 'hard' behaviourism (translation into physics) and Ryle's 'soft' behaviourism (dispositions). A key focus is Ryle's attack on the 'category mistake' of treating the mind as a separate 'thing'.

About This Topic

Philosophical Behaviourism is a physicalist theory that claims mental states are not 'inner' private events, but are instead reducible to outward behaviour or 'dispositions' to behave. Students study Hempel's 'hard' behaviourism (translation into physics) and Ryle's 'soft' behaviourism (dispositions). A key focus is Ryle's attack on the 'category mistake' of treating the mind as a separate 'thing'.

This topic is vital for understanding the 20th-century 'linguistic turn' in philosophy. It challenges the dualist 'ghost in the machine' model. This topic comes alive when students can physically model the patterns of behaviour that define a mental state, helping them see how a 'disposition' (like being 'fragile' or 'angry') works in practice.

Key Questions

1. Can mental states be translated into statements about behaviour without loss of meaning?
2. How does the asymmetry between self-knowledge and knowledge of others challenge behaviourism?
3. What is a category mistake?

Watch Out for These Misconceptions

Common Misconception

Behaviourism says we don't have thoughts.

What to Teach Instead

It says thoughts *are* just ways of behaving or being disposed to behave. Using the 'fragility' analogy (a glass is fragile even when not breaking) helps students understand 'dispositions'.

Common Misconception

Ryle and Hempel believe the exact same thing.

What to Teach Instead

Hempel wanted to translate mind-talk into the language of physics; Ryle was more interested in how we use ordinary language. Peer-mapping their differences helps students avoid oversimplification.

Active Learning Ideas

Simulation Game

The Disposition Game

Students are given a mental state (e.g., 'thirst'). Instead of saying how it feels, they must list 10 'if...then' behavioural dispositions (e.g., 'if offered water, they will drink'). This models Ryle's view of the mind.

Gallery Walk

Spot the Category Mistake

Stations show examples like 'I've seen the players and the pitch, but where is the team spirit?'. Students move around identifying why looking for a 'mind' in addition to 'behaviours' is, according to Ryle, a similar error.

Formal Debate

The Super-Spartans

Based on Putnam's thought experiment, students debate whether a 'Super-Spartan' (who feels pain but shows zero behaviour) proves behaviourism wrong. This tests the limits of reducing feelings to actions.

Frequently Asked Questions

What is a 'category mistake'?

Gilbert Ryle argued that dualists treat the 'mind' as if it belongs to the same logical category as 'body' (a thing/substance). He used the analogy of someone seeing all the colleges of a university and then asking 'but where is the University?', as if it were a separate building.

What is the difference between hard and soft behaviourism?

Hard behaviourism (Hempel) claims all mental states can be translated into statements about physical behaviour without losing meaning. Soft behaviourism (Ryle) argues mental states are 'dispositions' to behave in certain ways under certain conditions.

How can active learning help students understand behaviourism?

Behaviourism is about what we can *observe*. By using the 'Disposition Game', students stop thinking of the mind as a 'hidden room' and start seeing it as a set of observable patterns. This shift is much easier to grasp when they are actively defining those patterns themselves.

What is the 'asymmetry' objection?

It's the idea that I know my own mind through introspection, but I know yours through observation. Behaviourism suggests I should know my own mind by watching my own behaviour, which seems counter-intuitive.
