The paper discusses the challenges of defining the metaphysical commitments of non-naturalistic metanormative realism.
Interest in metanormative non-naturalism has resurfaced, necessitating clearer definitions of its commitments.
Prominent contemporary proposals focus on metaphysical grounding and essence but face criticism for overgeneralizing.
Non-naturalism is characterized by the belief in non-natural normative facts known through a priori reasoning.
Historical perspective shows a shift from skepticism to serious consideration of non-naturalism. G.E. Moore was a key figure in originally advocating this viewpoint.
Non-naturalists argue there are radical differences between normative and natural properties but often affirm supervenience and grounding relationships that suggest otherwise.
This tension highlights the need for improved characterizations of non-naturalist metaphysics.
Grounding: metaphysical determination relationships; represents how facts relate particularly where non-normative facts ground normative ones.
Current formulations often misclassify naturalistic hypotheses as non-naturalistic.
Essence relates to the identity of a property; proposals rely on the essence to distinguish natural from non-natural properties.
Essentialist formulations face similar overgeneralization concerns; they also misclassify properties that should be considered natural.
Recent approaches by philosophers like Rosen, Leary, and Berker utilize grounding and essence but misclassify intuitive hypotheses about normativity.
Examples highlight how non-naturalistic claims include misclassifications, especially regarding properties like badness being identical to fundamental natural properties (e.g., Painfulness).
A new framework focusing on objective similarity rather than supervenience or grounding is suggested.
Objective dissimilarity better aligns with the core intuitions motivating non-naturalism.
This perspective allows for distinguishing between classes of properties more accurately.
Similarity Non-naturalism: posits normative properties as a sui generis class based on objective similarities.
The authors argue that reliance on grounding and essence for formulating non-naturalism fails to adequately define its scope—often leading to misclassifications.
Emergentist Non-naturalism: combines similarity non-naturalism with the idea that normative facts could fully ground in non-normative facts, suggesting a nuanced understanding of normative properties.
Emphasizes further inquiry into relationships between normative and natural domains, aiming to clarify the metaphysical landscape surrounding non-naturalism.
