Plan
• Theory– Classical/Quantitative/Value/Default/
Benthamite/Old Skool Hedonism– Felt-Quality, Hedonic Tone theory of pleasure
• Problem– The heterogeneity problem
• Solution– Pleasure feels good– Scientific support for hedonic tone theories
![Page 3: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/3.jpg)
Classical Hedonism about Well-Being
• Well-being• Pleasure is the only
bearer of intrinsic value in a life
• Opposite for pain• Pleasure and pain are
sensations – they have a felt quality
• NOT ‘folk hedonism’
![Page 4: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/4.jpg)
Felt-Quality Theories of Pleasure
• Distinctive Feeling theories• Hedonic Tone theories• Every feeling/sensation has a valence
– Positive, neutral or negative
• Which affects well-being correspondingly– Improves, doesn’t change or worsens
• Note: the hedonic tone is felt/experienced
![Page 5: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/5.jpg)
The Heterogeneity Problem
• Henry Sidgwick (1907):– There is no common ‘felt’ feature in
diverse pleasurable experiences
• E.g. sex vs. schadenfraude• So, Felt-Quality theories were
largely abandoned • The value was taken out of the
sensation– Attitudinal pleasures– Motivational theories of pleasure– Preference-satisfaction accounts

The Kind of Solution Required
• Unify pleasure’s diversity• Is useful for Hedonism
– Is obviously good in itself
• Is compatible with folk concept of pleasure• Is compatible with best science• Is useful for Hedonistic Utilitarianism
– Is theoretically measurable and inter-personally comparable
![Page 7: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/7.jpg)
Motivational Theories of Pleasure – (MTP)
• Sidgwick, Brandt, Alston, Carson• Heathwood:
– A sensation is a sensory pleasure iff it is contemporaneously desired for its own sake
– But, not everything that is desired is a sensory pleasure
• Two problems1) How do we distinguish between pleasures and
non-pleasures?2) No role for pleasure in explaining motivation!?!

Feldman’s Attitudinal Pleasure
• Sensory pleasure = feeling “mmmmmm”/good – Intrinsically worthless
• Attitudinal pleasure = being pleased about something/enjoying it– The only thing of intrinsic
value
• E.g. the happy accident victim
![Page 9: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/9.jpg)
Assessing Attitudinal Pleasure
• Unifies pleasure’s diversity
• Is useful for Hedonism
• Is compatible with folk concept of pleasure
• Is compatible with best science
• Is useful for Hedonistic Utilitarianism

Recent Findings in Science 1
• “Pleasure is never merely a sensation”– Berridge & Kringelbach 2008, p459
• Reward = wanting liking & learning• Wanting and liking are dissociable• Wanting by itself seems a-pleasurable• Liking by itself seems pleasurable
![Page 12: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/12.jpg)
Causing Ratty Pleasure (‘Liking’)
![Page 13: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/13.jpg)
Recent Findings in Science 2
• The ‘liking’ circuitry uses opioids, cannabinoids & benzodiazepines
• The brain mechanisms for fundamental pleasures are probably the same for higher pleasures
• All experiences are coded with hedonic gloss
• Sometimes we become aware of this
![Page 14: Defining Pleasure for Hedonism: Lessons from Science Dan Turton Victoria University of Wellington](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56649c9e5503460f9495e33e/html5/thumbnails/14.jpg)
From Sensation to Subjective Pleasure
Sensory input
Primary sensory cortices: Cortical represen-tations created
Sense organs
Posterior OFC: Multi-modal integration
Anterior OFC: Reward value assigned
Lateral anterior OFC: Influences behaviour
Medial anterior OFC: Stored for learning
Mid-anterior OFC: Made available for subjective hedonic experience
?????????????: Conscious experience of pleasure

My Solution
• A Hedonic Tone theory• A scientifically grounded version of The
Feels Good Theory of pleasure• Pleasure (enjoyment) = Being aware of +ve
hedonic gloss• Pain (suffering) = Being aware of -ve
hedonic gloss• Being aware• Hedons
– Duration– Felt Intensity (awareness * intensity)

Assessing My Simple Pleasure
• Unifies pleasure’s diversity
• Is useful for Hedonism
• Is compatible with folk concept of pleasure
• Is compatible with best science
• Is useful for Hedonistic Utilitarianism

Recap
• The Problem• Feldman’s solution:
– Attitudinal pleasure
• My solution– A Hedonic Tone theory– Pleasure (enjoyment) = Being aware of
positive hedonic gloss– Pain (suffering) = Being aware of negative
hedonic gloss
