The dedifferentiation problem

This article demonstrates that our more sophisticated theories of law lead us to a point where we are no longer able to distinguish law from culture, or society, or the market, or politics or anything of the sort. Not only are the various terms inextricably intertwined (something that other thinkers have observed) but we are no longer in a position to articulate any relations between these various terms at all. It is with this latter realization that the dedifferentiation problem kicks in. Because the various terms cannot be disentangled, we find ourselves in the odd position where there is nothing of any positive character to be said about their relations. Each is already the other and, thus, they can have no relation. This is rather bad news for the ways in which we have traditionally conceived theories of law—indeed any theory that gets off the ground by distinguishing law from a discrete something else (which, on first glance, would seem to include all legal theory).

Defining ‘Dead’ in Terms of ‘Lives’ and ‘Dies’

What is it for a thing to be dead? Fred Feldman holds, correctly in my view, that a definition of ‘dead’ should leave open both (1) the possibility of things that go directly from being dead to being alive, and (2) the possibility of things that go directly from being alive to being neither alive nor dead, but merely in suspended animation. But if this is right, then surely such a definition should also leave open the possibility of things that go directly from being dead to being neither alive nor dead, but merely in suspended animation. I show that Feldman’s own definition of ‘dead’ (in terms of ‘lives’ and ‘dies’) does not leave this possibility open. I propose a new definition that does.     

God as Spirit—and Natural Science

The biblical sentence "God is Spirit" (John 4:24) occasioned the development of the Christian doctrine about God as Spirit. But since patristic times "spirit" was interpreted in the sense of Nus, which rather means "intellect." The biblical concept of spirit (pneuma), however, has its root meaning in referring to "air in movement," as in breath or storm. The similar concept of pneuma in Stoic philosophy has become the "immediate precursor" (Max Jammer) of the field concept in modern physics, so that the conclusion is suggested that God is spirit as something like a field of force rather than as intellect. This essay argues for such a conception by relating the divine eternity and immensity to the concepts of space and time, the basic requirements of any physical field. God's eternity and immensity are interpreted in terms of undivided infinite space (and time) which is presupposed in all concepts of parts of space or time (or space-time), therefore in all mathematical and physical measurement.     

RESPONSE TO CRITIQUES OF RELIGION IN AN AGE OF SCIENCE

Abstract. In replying to the four thoughtful critiques of my first Gifford volume I try to clarify the differences among us. I defend my use of Kuhn's concept of paradigms against Nancey Murphy's use of Lakatos's concept of research programs and then compare both of us with advocates of the “strong program” in the social construction of science. Sallie McFague identifies me with the empiricist, objectivist, “modernist” tradition and contrasts it to her own “postmodernist” acceptance of cultural relativism and the social construction of science, but I argue that I am seeking an intermediate position that redefines objectivity rather than rejecting it. Some themes common to feminist and process theology are also examin ed. In dialogue with Bob Russell I discuss the metaphysical and theological implications of the unity of space and time in relativity, the beginning of time in recent cosmology, and the thesis that God acts by determining events in indeterminate quantum systems. Finally I compare John Cobb's indebtedness to Whitehead with my own and suggest that I am more willing to adapt or modify process thought in the interpretation of scientific theories and religious experience.     

DIVINE ACTION: IS IT CREDIBLE?

Abstract. The concept of God's acting in the world has been seen to be problematic in light of the claims of scientific knowledge that the regularity of a law like universe rules out divine action. There are resources in both scientific knowledge and religion that can render meaningful and credible divine action. The new physics, chaos theory, cognitive psychology, and the concept of top-down causation are used to understand how God acts in the world. God's action is not an intervention, but is understood on the model of how the mind influences the brain in a downward causative manner. Suggestions for imagining God's actions are discussed.     

BREAKING A TABOO: FRANK TIPLER'S THE PHYSICS OF IMMORTALITY

Abstract. In his book The Physics of Immortality. Frank Tipler has broken a longstanding intellectual taboo by dealing as a physicist with the theological themes of God and immortality, as well by arguing that theology can provide material for concept formation in the field of physics. His work on the anthropic principle convinced Tipler that, since the emergence of intelligent life is of the essence of the universe as a whole, the future of life is of fundamental significance. His Omega Point theory takes theological theories of the future's significance seriously from a scientific point of view. Theories of computers play a central role in Tipler's theory of immortality, and even though many critics have misunderstood his thrust in these theories, they are worthy of further exploration. Perhaps Tipler's most important contribution is his insistence that the world as described by physics is more open to interaction with biblical and theological perspectives than is often believed.     

Formation of semantic associations between subliminally presented face-word pairs

Recent evidence suggests that consciousness of encoding is not necessary for the rapid formation of new semantic associations. We investigated whether unconsciously formed associations are as semantically precise as would be expected for associations formed with consciousness of encoding during episodic memory formation. Pairs of faces and written occupations were presented subliminally for unconscious associative encoding. Five minutes later, the same faces were presented suprathreshold for the cued unconscious retrieval of face-occupation associations. Retrieval instructions required participants to classify the presented individuals according to their putative (1) regularity of income, (2) length of education, and (3) creativity value of occupational activity. The three instructions yielded more classifications consistent with a person’s occupation if the person had been subliminally presented with his written occupation versus a meaningless word (control condition). This suggests that consciousness is not necessary to encode, long-term store, and retrieve semantically precise associations between primarily unrelated items.     

Dynamic action in virtual environments: Constraints on the accessibility of action knowledge in children and adults

In a series of three experiments, we probed the accessibility of action knowledge in different versions of a virtual environment (VE) with 7-year-old children and adults. Using a PHANToM^TM haptic interface, participants performed a virtual throwing task in which they tried to propel a ball from a table to hit a target on the ground. In Experiments 1 and 2, the virtual scene was presented on a computer monitor, and, in Experiment 3, it was projected by using a video projector so that the vertical and horizontal dimensions and the spatial location of the VE corresponded to the real-world dimensions. Results indicate that action knowledge is accessible even in a nonimmersive VE, but also suggest that the need to recalibrate perceptual-motor mappings constrains the accessibility of this kind of intuitive knowledge.     

An asymmetric effect of relational integration on recognition memory

Two experiments assessed whether conceptual relations (e.g., contains: cookie jar) facilitate the retrieval of concepts (e.g., cookie and jar) from long-term memory. The CARIN model of nominal combination asserts that conceptual relations are represented with and selected from the modifier noun (cookie). Thus, the model predicts that relational integration will facilitate memory for modifiers but not for head nouns (jar). In Experiment 1, concepts were studied in pairs and were then tested individually. Recognition accuracy was higher for modifiers than for head nouns. In Experiment 2, the studied concepts (e.g., cookie jar) were tested in the context of a new pair that instantiated either the same relation (e.g., cookie plate) or a different relation (e.g., cookie crumb). Recognition was again better for modifiers than for head nouns, but only when the same conceptual relation was instantiated at both study and test. Thus, results indicate that conceptual relations (a) facilitate recognition memory, and (b) are associated more strongly with the modifier than with the head noun.     

The effects of ageing and visual noise on conceptual integration during sentence reading

The effortfulness hypothesis implies that difficulty in decoding the surface form, as in the case of age-related sensory limitations or background noise, consumes the attentional resources that are then unavailable for semantic integration in language comprehension. Because ageing is associated with sensory declines, degrading of the surface form by a noisy background can pose an extra challenge for older adults. In two experiments, this hypothesis was tested in a self-paced moving window paradigm in which younger and older readers’ online allocation of attentional resources to surface decoding and semantic integration was measured as they read sentences embedded in varying levels of visual noise. When visual noise was moderate (Experiment 1), resource allocation among young adults was unaffected but older adults allocated more resources to decode the surface form at the cost of resources that would otherwise be available for semantic processing; when visual noise was relatively intense (Experiment 2), both younger and older participants allocated more attention to the surface form and less attention to semantic processing. The decrease in attentional allocation to semantic integration resulted in reduced recall of core ideas in both experiments, suggesting that a less organized semantic representation was constructed in noise. The greater vulnerability of older adults at relatively low levels of noise is consistent with the effortfulness hypothesis.
