Abstract

David Wallace’s ‘Dennett’s Criterion’ plays a key part in establishing realist claims about the existence of a multiverse emerging from the mathematical formalism of quantum physics, even after decoherence is fully appreciated. Although the philosophical preconditions of this criterion are not neutral, they are rarely explicitly addressed conceptually. I tease apart three: (I) a rejection of conceptual bridge laws even in cases of inhomogeneous reduction; (II) a reliance on the pragmatic notion of usefulness to highlight quasi-classical patterns, as seen in a decoherence basis, over others; and (III) a structural realist or ‘functional realist’ point of view that leads to individuating those patterns as real macroscopic objects at the coarse-grained level, as they are seen from the Classical Stance (analogous to Dennett’s Intentional Stance). I conclude that the justification of Dennett’s Criterion will be intimately tied up with the fate of strong forms of naturalism, and in particular that Wallacian quantum mechanics is a key case study for concretely evaluating his ‘math-first’ structural realism (Wallace 2022).

经典立场:瓦拉几量子力学中的丹尼特标准。
戴维-华莱士的 "丹尼特标准"(Dennett's Criterion)在量子物理学的数学形式主义中建立多元宇宙存在的现实主义主张方面发挥了关键作用,即使在退相干得到充分理解之后也是如此。尽管这一标准的哲学先决条件并非中性,但它们很少在概念上被明确提及。我将其分为三点:(I)即使在非均质还原的情况下,也拒绝概念桥接定律;(II)依赖实用性概念来突出准经典模式,如在退相干基础上看到的模式,而不是其他模式;以及(III)结构现实主义或 "功能现实主义 "观点,这种观点导致在粗粒度层面将这些模式单独视为真实的宏观对象,如从经典立场(类似于丹尼特的意图立场)所看到的那样。我的结论是,丹尼特标准的合理性将与强自然主义形式的命运紧密联系在一起,尤其是华莱士量子力学是具体评估其 "数学第一 "结构现实主义的关键案例研究(华莱士,2022 年)。

期刊介绍: Studies in History and Philosophy of Science is devoted to the integrated study of the history, philosophy and sociology of the sciences. The editors encourage contributions both in the long-established areas of the history of the sciences and the philosophy of the sciences and in the topical areas of historiography of the sciences, the sciences in relation to gender, culture and society and the sciences in relation to arts. The Journal is international in scope and content and publishes papers from a wide range of countries and cultural traditions.
