Against Explanatory Minimalism in Psychiatry

Area of Science:

• Philosophy of Psychiatry
• Cognitive Science
• Philosophy of Mind

Background:

• The concept of multiple levels of explanation in psychiatry has faced criticism, including claims of empirical falsity and conceptual unintelligibility.
• Campbell's critique, rooted in interventionist causality, questions the basis for distinct explanatory levels in both physical and mental domains.
• Superficial similarities exist between Campbell's critique and remarks by Wittgenstein in Zettel.

Purpose of the Study:

• To re-evaluate the validity of multiple levels of explanation in psychiatry.
• To explore the philosophical underpinnings of psychiatric explanation, particularly concerning causation and mental states.
• To reconcile the need for specific explanatory levels for mental phenomena with the rejection of a priori links to neurology.

Main Methods:

• Philosophical analysis of causation and explanation in psychiatry.
• Comparative study of Campbell's interventionist critique and Wittgenstein's philosophy.
• Contextual interpretation of Wittgenstein's remarks on mental causation and explanation.
• Examination of propositional attitude attribution, including in cases of delusion.

Main Results:

• Campbell's critique, while influential, may stem from an incomplete understanding of causation and explanation.
• Wittgenstein's philosophy, when properly contextualized, supports a richer notion of explanatory levels than minimalist accounts allow.
• An interventionist framework alone is insufficient for justifying the attribution of propositional attitudes, especially in complex cases like delusions.
• A Wittgenstein-informed perspective can validate the necessity of particular explanatory levels for mental phenomena without asserting a necessary a priori connection to neurological levels.

Conclusions:

• Explanatory minimalism in psychiatry should be rejected in favor of a Wittgensteinian approach to levels of explanation.
• Understanding mental phenomena, including delusions, requires a broader philosophical context than interventionism provides.
• The attribution of mental states is justified within specific explanatory contexts, not necessarily tied a priori to a single neurological level.
