Aesthetics and morality judgments share cortical neuroarchitecture

Area of Science:

• Neuroscience
• Cognitive Science
• Philosophy of Mind

Background:

• Philosophical traditions largely separate morality and aesthetics.
• Empirical evidence regarding the neural basis of these judgments remains limited.

Purpose of the Study:

• To investigate the neural underpinnings of aesthetic and moral judgments.
• To empirically test the distinctness versus commonality of neural representations for these two domains.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used to measure brain activity.
• Participants judged artwork beauty and action goodness, with content-controlled tasks (artwork age, action speed).
• Univariate and multivariate analyses examined common and distinct brain activations and representations.

Main Results:

• Common brain activation was found in prefrontal cortex regions (frontopolar, dorsomedial, ventrolateral) for both judgment types.
• Distinct activations were observed: temporoparietal cortex for morality, occipital cortex for aesthetics.
• Multivariate analyses confirmed both shared and unique neural representations in prefrontal and temporoparietal areas.

Conclusions:

• Neural commonalities between moral and aesthetic judgments are more substantial than typically assumed in philosophy.
• Findings support theoretical accounts emphasizing shared valuation processes or sentimentalist perspectives.
• The study provides empirical grounding for reconsidering the separation of moral and aesthetic cognition.
