Multi-Centered Worlds,Limited Accessibility and Ways of Believing

Philosophia - Recent descendants of David Lewis, such as Stephen Torre, Dilip Ninan, and Dirk Kindermann have utilized multi-centered propositions, which are roughly sets of possible worlds...     

Impossible Worlds

Impossible worlds are representations of impossible things and impossible happenings. They earn their keep in a semantic or metaphysical theory if they do the right theoretical work for us. As it happens, a worlds‐based account provides the best philosophical story about semantic content, knowledge and belief states, cognitive significance and cognitive information, and informative deductive reasoning. A worlds‐based story may also provide the best semantics for counterfactuals. But to function well, all these accounts need use of impossible and as well as possible worlds. So what are impossible worlds? Graham Priest claims that any of the usual stories about possible worlds can be told about impossible worlds, too. But far from it. I'll argue that impossible worlds cannot be genuine worlds, of the kind proposed by Lewis, McDaniel or Yagisawa. Nor can they be ersatz worlds on the model proposed by Melia or Sider. Constructing impossible worlds, it turns out, requires novel metaphysical resources.     

Worlds within Worlds: Kabbalah and the New Scientific Paradigm

Beginning with relativity and quantum theory, the deterministic view that has dominated and shaped Western culture for more than 2,500 years has begun to unravel, leading to the emergence of a new paradigm. This new paradigm effectively reformulates the project of science, conceiving of existence as an interpenetrating web of coevolving, cocreative relationships. By exploring Kabbalah and the new scientific paradigm within the context of shared evolutionary principles, I seek to demonstrate a viable alternative to the prevailing deterministic worldview. By going beyond the limits of determinism and re–visioning existence as an evolutionary, emergent phenomenon, we can establish a new basis for an authentic dialogue between science and religion.     

Worlds and times

In the fourteenth century, Duns Scotus suggested that the proper analysis of modality required not just moments of time but also ??moments of nature??. In making this suggestion, he broke with an influential view first presented by Diodorus in the early Hellenistic period, and might even be said to have been the inventor of ??possible worlds??. In this essay we take Scotus?? suggestion seriously devising first a double-index logic and then introducing the temporal order. Finally, using the temporal order, we define a modal order. This allows us to present modal logic without the usual interpretive questions arising concerning the relation called variously ??accessibility??, ??alternativeness??, and, ??relative possibility.?? The system in which this analysis is done is one of those which have come to be called a hybrid logic.     

Actualism and Higher-Order Worlds

It has been argued that actualism – the view that there are no non-actual objects – cannot deal adequately with statementsinvolving iterated modality, because such claims require reference, either explicit or surreptitious, to non-actualobjects. If so, actualists would have to reject the standard semantics for quantified modal logic (QML). In this paper I develop an account of modality which allows the actualist tomake sense of iterated modal claims that are ostensibly aboutnon-actual objects. Every occurrence of a modal operatorinvolves the stipulation of a possible world, and nestedmodal operators require stipulation of nested possible worlds.I provide an actualistically acceptable (AA) semantics for QMLwherein the nesting relation is irreflexive and intransitive and forms a tree. Despite these restrictions, AA models can beshown to be sound and complete for a wide variety of modal logics.     

Two Worlds: African American Men's Negotiation of Predominantly White Educational and Occupational Worlds

Negotiating 2 worlds, a predominantly White opportunity structure and one's community of origin, often produces distress among persons of color. in this qualitative study, the author examines the perspectives and competencies of African American men who negotiate 2 worlds and suggests that bicultural competence may facilitate participation in the opportunity structure while maintaining identification with one's racial group. Desenvolverse en dos mundos, una estructura de oportunidades predominantemente Blanca y la propia comunidad de origen, genera con frecuencia angustia entre las personas de color. En este estudio cualitativo, el autor examina las perspectivas y competencias de varones Afroamericanos que se desenvuelven en dos mundos distintos y sugiere que la competencia bicultural puede facilitar su participación en la estructura de oportunidades, manteniendo a la vez la identificación con el propio grupo racial.
