It is argued that the conjunction effect has a disjunctive analog of strong interest for the realism–antirealism debate. It
is possible that a proper theory is more confirmed than its (more probable) observational sub-theory and hence than the latter’s
disjunctive equivalent, i.e., the disjunction of all proper theories that are empirically equivalent to the given one. This
is illustrated by a toy model. 相似文献

I examine the role of inference from experiment in theory building. What are the options open to the scientific community when faced with an experimental result that appears to be in conflict with accepted theory? I distinguish, in Laudan’s (1977), Nickels’s (1981), and Franklin’s (1993) sense, between the context of pursuit and the context of justification of a scientific theory. Making this distinction allows for a productive middle position between epistemic realism and constructivism. The decision to pursue a new or a revised theory in response to the new evidence may not be fully rationally determined. Nonetheless, it is possible to distinguish the question of whether there is reason to pursue a theory from the question of whether that theory, once it has been pursued over time, solves a problem of interest to science. I argue that, in this context, there is a solid way to distinguish between the contexts of pursuit and of justification, on the basis of a theory’s evidential support and problem-solving ability. 相似文献

This paper describes and defends the view that minimal chemical life essentially involves the chemical integration of three
chemical functionalities: containment, metabolism, and program (Rasmussen et al. in Protocells: bridging nonliving and living
matter, 2009a). This view is illustrated and explained with the help of CMP and Rasmussen diagrams (Rasmussen et al. In: Rasmussen et al.
(eds.) in Protocells: bridging nonliving and living matter, 71–100, 2009b), both of which represent the key chemical functional dependencies among containment, metabolism, and program. The CMP model
of minimal chemical life gains some support from the broad view of life as open-ended evolution, which I have defended elsewhere
(Bedau in The philosophy of artificial life, 1996; Bedau in Artificial Life, 4:125–140, 1998). Further support comes from the natural way the CMP model resolves the puzzle about whether life is a matter of degree. 相似文献

Tom Stoneham put forward an argument purporting to show that coherentists are, under certain conditions, committed to the
conjunction fallacy. Stoneham considers this argument a reductio ad absurdum of any coherence theory of justification. I argue that Stoneham neglects the distinction between degrees of confirmation
and degrees of probability. Once the distinction is in place, it becomes clear that no conjunction fallacy has been committed. 相似文献

Emergence is interpreted in a non-dualist framework of thought. No metaphysical distinction between the higher and basic levels
of organization is supposed, but only a duality of modes of access. Moreover, these modes of access are not construed as mere
ways of revealing intrinsic patterns of organization: They are supposed to be constitutive of them, in Kant’s sense. The emergent levels of organization, and the inter-level causations as well, are therefore neither
illusory nor ontologically real: They are objective in the sense of transcendental epistemology. This neo-Kantian approach defuses several paradoxes associated with the concept
of downward causation, and enables one to make good sense of it independently of any prejudice about the existence (or inexistence)
of a hierarchy of levels of being. 相似文献

The mathematical nature of modern science is an outcome of a contingent historical process, whose most critical stages occurred in the seventeenth century. ‘The mathematization of nature’ (Koyré 1957, From the closed world to the infinite universe, 5) is commonly hailed as the great achievement of the ‘scientific revolution’, but for the agents affecting this development it was not a clear insight into the structure of the universe or into the proper way of studying it. Rather, it was a deliberate project of great intellectual promise, but fraught with excruciating technical challenges and unsettling epistemological conundrums. These required a radical change in the relations between mathematics, order and physical phenomena and the development of new practices of tracing and analyzing motion. This essay presents a series of discrete moments in this process. For mediaeval and Renaissance philosophers, mathematicians and painters, physical motion was the paradigm of change, hence of disorder, and ipso facto available to mathematical analysis only as idealized abstraction. Kepler and Galileo boldly reverted the traditional presumptions: for them, mathematical harmonies were embedded in creation; motion was the carrier of order; and the objects of mathematics were mathematical curves drawn by nature itself. Mathematics could thus be assigned an explanatory role in natural philosophy, capturing a new metaphysical entity: pure motion. Successive generations of natural philosophers from Descartes to Huygens and Hooke gradually relegated the need to legitimize the application of mathematics to natural phenomena and the blurring of natural and artificial this application relied on. Newton finally erased the distinction between nature’s and artificial mathematics altogether, equating all of geometry with mechanical practice. 相似文献

The paper investigates the propriety of applying the form versus matter distinction to arguments and to logic in general.
Its main point is that many of the currently pervasive views on form and matter with respect to logic rest on several substantive
and even contentious assumptions which are nevertheless uncritically accepted. Indeed, many of the issues raised by the application
of this distinction to arguments seem to be related to a questionable combination of different presuppositions and expectations;
this holds in particular of the vexed issue of demarcating the class of logical constants. I begin with a characterization
of currently widespread views on form and matter in logic, which I refer to as ‘logical hylomorphism as we know it’—LHAWKI,
for short—and argue that the hylomorphism underlying LHAWKI is mereological. Next, I sketch an overview of the historical
developments leading from Aristotelian, non-mereological metaphysical hylomorphism to mereological logical hylomorphism (LHAWKI).
I conclude with a reassessment of the prospects for the combination of hylomorphism and logic, arguing in particular that
LHAWKI is not the only and certainly not the most suitable version of logical hylomorphism. In particular, this implies that
the project of demarcating the class of logical constants as a means to define the scope and nature of logic rests on highly
problematic assumptions. 相似文献

In the present article, the lexical contribution to nonword reading was evaluated using Italian pseudohomophones that contained
atypical letters or letter sequences. Pseudohomophones were read faster than orthographically matched nonwords in both mixed
(Experiment 1) and pure (Experiment 2) lists; in addition, a base-word frequency effect was obtained in both conditions. The same pseudohomophone advantage was
observed when nonwords without atypical letter sequences were mixed in the experimental list (Experiment 3 ), and it disappeared only in lexical decision, in which pseudohomophones were rejected as quickly as control nonwords. The
pattern of results was explained by assuming that, due to their orthographic properties, the Italian pseudohomophones did
not benefit from an orthographic lexical contribution and were mainly processed through the interaction system between the
sublexical mechanisms and the phonological output lexicon. 相似文献

Holding an intention often interferes with other ongoing activities, indicating that resource-demanding processes are involved
in maintaining the intention and noticing the appropriate event to fulfill it. Little is known, however, about the nature
of the processes underlying this task interference effect. The goal of the present research was to decompose the processes
contributing to the task interference effect by applying the diffusion model (Ratcliff, Psychological Review 85:59–108, 1978) to an event-based prospective memory task. In the first experiment, we validated the interpretation of the response criterion
parameter (a) of the diffusion model as reflecting strategies to cope with the anticipated demands of a prospective memory task in the
context of the ongoing task. The second experiment served to investigate which underlying processes contribute to the task
interference often found with prospective memory tasks. Diffusion model analyses revealed that the task interference effect
was due to (1) less efficient processing in the more demanding than in the less demanding prospective memory task and (2)
a more conservative response criterion. We suggest that the anticipated demands and the additional processing demands of the
prospective memory task jointly contribute to the task interference effect. 相似文献

How a hobby can shape cognition: visual word recognition in competitive Scrabble players 总被引:1,自引:0,他引:1
Competitive Scrabble is an activity that involves extraordinary word recognition experience. We investigated whether that
experience is associated with exceptional behavior in the laboratory in a classic visual word recognition paradigm: the lexical
decision task (LDT). We used a version of the LDT that involved horizontal and vertical presentation and a concreteness manipulation.
In Experiment 1, we presented this task to a group of undergraduates, as these participants are the typical sample in word recognition studies.
In Experiment 2, we compared the performance of a group of competitive Scrabble players with a group of age-matched nonexpert control participants.
The results of a series of cognitive assessments showed that the Scrabble players and control participants differed only in
Scrabble-specific skills (e.g., anagramming). Scrabble expertise was associated with two specific effects (as compared to
controls): vertical fluency (relatively less difficulty judging lexicality for words presented in the vertical orientation)
and semantic deemphasis (smaller concreteness effects for word responses). These results suggest that visual word recognition
is shaped by experience, and that with experience there are efficiencies to be had even in the adult word recognition system. 相似文献
