Analysing Modality

This chapter presents and defends the basic tenets of quantum modal realism. The first of these principles, Individualism, states that Everett worlds are metaphysically possible worlds. The converse of this principle, Generality, states that metaphysically possible worlds are Everett worlds. Combining Individualism and Generality yields Alignment, a conjecture about the nature of possible worlds that is closely analogous to Lewisian modal realism. Like Lewisian modal realism, Alignment entails that each possible world is a real concrete individual of the same basic kind as the actual world. These similarities render EQM suitable for grounding a novel theory of the nature of metaphysical modality with some unique properties. Also like Lewisian modal realism, quantum modal realism is a reductive theory: it accounts for modality in fundamentally non-modal terms. But quantum modal realism also has unique epistemological advantages over Lewisian modal realism and other extant realist approaches to modality.

50 Years of Gettier: A New Direction in Religious Epistemology?

In this paper, I lend credence to the move toward non-reductive religious epistemology by highlighting the systematic failings of Alvin Plantinga’s seminal, religious epistemology when it comes to surmounting the Gettier Problem. Taking Plantinga’s account as archetypal, I argue that we have systematic reasons to believe that no reductive theory of knowledge (religious or otherwise) can viably surmount the Gettier Problem, that the future of religious epistemology lies in non-reductive models of knowledge.

Group Intentions and Oppression

A reductive theory of collective intentionality would imply that the ‘official’ intentions of an oppressive political authority cannot be constructed from the intentions of individuals when they follow the authority's rules. This makes it difficult to explain the unraveling of official group plans through time in a seemingly consistent fashion, and the corresponding source of coercion. A non-reductive theory, on the other hand, cannot capture whether the actions of individuals in an oppressive society are free or coerced, so long as a manifest institutional structure and rules are in place. I put forward a hybrid account of group intentionality that is capable of articulating why oppressive political power is illegitimate, which comes down to the official and individual intentions in joint group actions diverging in such a way that individuals are not governed on the basis of dependent reasons.

On Abstract Intelligence and Brain Informatics

A key notion in abstract intelligence and cognitive informatics is that the brain and natural intelligence may only be explained by a hierarchical and reductive theory that maps the brain through the embodied neurological, physiological, cognitive, and logical levels from bottom-up induction and top-down deduction. This paper presents an abstract intelligence framework for modeling the structures and functions of the brain across these four levels. A set of abstract intelligent model, cognitive functional model, and neurophysiological model of the brain is systematically developed. On the basis of the abstract intelligent models of the brain at different levels, the conventionally highly overlapped, redundant, and even contradicted empirical observations in brain studies and cognitive psychology may be rigorously clarified and neatly explained. The improved understanding about the brain has led to the development of a wide range of novel technologies and systems such as cognitive computers, cognitive robots, and other applied cognitive systems.

Relations Without Forms: Some Consequences of Aquinas’s Metaphysics of Relations

This article presents a new interpretation and critique of some aspects of Aquinas’s metaphysics of relations, with special reference to a theological problem—the relation of God to creatures—that catalyzed Aquinas’s and much medieval thought on the ontology of relations. I will show that Aquinas’s ontologically reductive theory of categorical real relations should equip him to identify certain relations as real relations, which he actually identifies as relations of reason, most notably the relation of God to creatures.
