Internal Condition

Extant internalists are either accessibilists or mentalists. Accessibilists standardly claim that whenever p is justified, one is in a position to know this fact by reflection alone or else this fact has grounds that are accessible in this way. The argument for this claim assumes that one ought to believe p only if p is justified; that therefore, grounds for justification must be luminous; and that only facts accessible by reflection fit the bill. It founders already because too few conditions are luminous. A non-standard version of accessibilism avoids this problem by conceiving of the grounds for justification as facts about what one is in a position to know by reflection alone. The argument marshalled in its favour fails to show why they cannot be facts about what one is in a position to know by other means. Mentalists claim that whenever p is justified this fact is grounded in facts about one’s mental states. One argument contends that only mentalism can account for certain structural features of justification. It founders because the present account explains these features equally well. Another argument contends that only mentalism heeds our intuitions about sceptical cases. It founders because mental states can help to confer justification only if they are arrived at in certain ways—a fact not itself determined by such states. Accessibilism and mentalism lack sufficient support and incur costs internalists do better without. The present account delivers all the goods that internalists should wish for, without making justification an internal condition.

Rational Actions

This paper aims to discuss psychological aspect of rational choice theory. The standard version of rational choice rests on a kind of psychology, since it operates with mental states. In standard davidsonian version it is claimed that we explain rational actions by stating proper desires and beliefs that caused the action. We will explore two challenges to the standard version that might be called cultural and naturalistic versions of rational choice. Satz and Ferejohn (1994) challenged standard version by stating that we can provide rational-choice explanations without relying too much on psychological assumptions. They argued in favor of moderate externalism, which should replace thin desire-belief model with thick structuralist conception. According to their model moderate externalism is compatible with realism about psychological states, while at the same time those states need not figure in the best rational choice explanations of actions. The focus of rational choice explanations therefore shifts to non-individual and non-psychological entities, such as firms in explaining economic behavior, parties in explaining functioning of democracy, etc. Although there is a place for psychological states within a moderate externalism, those states are not causally relevant. On Pettit?s account desires and beliefs figure in rational choice explanations merely as ?standby causes?. They explain resilience of certain behavior, not its actual cause. Quite contrary to standard rational choice theory, the programming model (Pettit, 2002) defines the neurophysiological level as more basic in explaining behavior. This means that higher-level psychological states are causally relevant for certain behavior only if certain lower-level neurophysiological producer obtains. In this paper standard rational choice theory will be defended against culturalist and naturalist criticism.

The Relationship

To what extent are theological questions knowable? This chapter outlines some tools for addressing this question by first giving some plausible structural constraints on knowledge. These constraints include the absence of false beliefs in nearby worlds, connections to other mental states, and the relationship between knowledge and rationality and moral worth. Then it uses these constraints to explore the relationship between the possibility (or impossibility) of theological knowledge and various issues including private interpretation, faith, the problem of evil, religious diversity, and morally good action. Even with these relatively simple structural features of knowledge in hand, we can outline some potential difficulties for familiar discussions in the epistemology of theology, and point to some new considerations that bear on familiar questions. Thus we hope to show that careful thinking about the structural constraints on knowledge, especially as related to sceptical concerns, is of interest to familiar epistemological debates in theology.

Purpose. The article is aimed to analyse the phenomenon of bodily memory in the context of commemorative practices. The commemorative practices are a social instrument known since archaic times, which had different ways of use in different epochs. In totalitarian societies, officially organized commemorative practices are frequently used for propaganda and manipulation. For most people, their mechanism remains unconscious, as bodily memory plays a leading role there. The density of a modern social world actualises the ability to observe own changes and regulate the processes of their flow. This updates an exploration of the bodily memory phenomenon. Theoretical basis. The classification of forms of bodily memory is carried out in the article: genetic (cellular memory, heredity), psychophysical (memory for different types of sensations, skills, muscle tone, etc.), psychoenergetic (emotions, mental states, mood, unconscious action, etc.), mental (knowledge of the rules of social games, attitudes, stereotypes, thoughts, memories, ways of our detection, behaviour, etc.). It has been revealed that the systemic openness of bodily memory is the fundamental basis of commemorative practices. Originality. The term "conscious commemoration" is proposed to denote the anthropological process associated with self-knowledge, self-construction and co-creation, which requires a distinction between forms of bodily memory, understanding of its structural features and functional capabilities. Conclusions. The phenomenon of bodily memory reveals the anthropological potential of commemorative practices. It can manifest itself as an independently organized body-spiritual practice of self-construction (harmonization of the architecture of one’s own body and individuality) on the basis of self-knowledge and self-observation (directing attention to one’s movements, reactions, behaviour, honest recognition of one’s attitudes). The latter is the foundation of conscious co-creation. The phenomenon of bodily memory reveals the secret of spiritualization in the process of approaching a person to his body.

Justification as Ignorance offers an original account of epistemic justification as both non-factive and luminous that vindicates core internalist intuitions, without construing justification as an internal condition. The account conceives of justification, in its doxastic and propositional varieties, as a kind of epistemic possibility of knowing, and of being in a position to know, respectively. It thus contrasts with other recently proposed views that characterize justification in terms of the metaphysical possibility of knowing. In developing his account, Rosenkranz devises a suitable non-normal multi-modal epistemic logic for knowledge and being in a position to know that respects the finding that these notions create hyperintensional contexts, defends his conception of justification against well-known anti-luminosity arguments, shows that the account allows for fruitful applications and principled solutions to the lottery and preface paradoxes, and provides a metaphysics of justification, and of its varying degrees of strength, that is compatible with core assumptions of the knowledge-first approach and disjunctivist conceptions of mental states.

Drawing on recent work on digital narratives of personal experience in online genres such as email, social networking sites, and blogs, the present study explores narrative features in 100 online consumer reviews of hotels. Focusing on negative reviews, or “Rants,” from popular consumer travel platform, TripAdvisor, the article examines both canonical and genre-specific structural features of narratives, as well as some of the discursive resources used by online narrators to engage their audiences, and to draw them into their stories. Specifically, the study explores the use of story prefaces and related forms of second person address, represented speech and mental states, and deictic shifts, and suggests that narrative features such as these are useful in attracting the attention of an audience amidst a vast universe of online information.

Negative Introspection

Core theses of the novel account of justification to be developed are first stated: one has propositional justification for p just in case one is in no position to know that one is in no position to know p; and one has doxastic justification for p just in case one is in no position to know that one does not know p. Unlike other theories that conceive of justification in terms of the metaphysical possibility of knowing, the present account thus construes it as a distinctive kind of epistemic possibility. It treats propositional justification as non-factive, both its presence and its absence as luminous conditions, and by assuming a weak non-normal modal logic for knowledge and being in a position to know, validates principles of positive and negative introspection for it. The account thereby attributes features to justification that internalists care about. But it does so without construing justification as an internal condition. The account allows one to systematically distinguish between the condition of being justified and the metaphysical grounds for its obtaining, thereby heeding externalist insights into the difference between the good cases and the bad cases envisaged by radical scepticism. Lines of argument that show the account’s potential, e.g. in dealing with the preface and lottery paradoxes, are previewed, and so are lines of defence against challenges and objections, including prominent anti-luminosity arguments.

Commercial polyimide films have shown to be homogeneous on a scale of 5 to 200 nm. The observation of Skybond (SKB) 705 and PI5878 was carried out by using a Philips 400, 120 KeV STEM. The objective was to elucidate the structural features of the polymeric samples. The specimens were spun and cured at stepped temperatures in an inert atmosphere and cooled slowly for eight hours. TEM micrographs showed heterogeneities (or nodular structures) generally on a scale of 100 nm for PI5878 and approximately 40 nm for SKB 705, present in large volume fractions of both specimens. See Figures 1 and 2. It is possible that the nodulus observed may be associated with surface effects and the structure of the polymers be regarded as random amorphous arrays. Diffraction patterns of the matrix and the nodular areas showed different amorphous ring patterns in both materials. The specimens were viewed in both bright and dark fields using a high resolution electron microscope which provided magnifications of 100,000X or more on the photographic plates if desired.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Highly ordered or crystalline biological macromolecules become severely damaged and structurally disordered after a brief electron exposure. Evidence that damage and structural disorder are occurring is clearly given by the fading and eventual disappearance of the specimen's electron diffraction pattern. The fading and disappearance of sharp diffraction spots implies a corresponding disappearance of periodic structural features in the specimen. By the same token, there is a oneto- one correspondence between the disappearance of the crystalline diffraction pattern and the disappearance of reproducible structural information that can be observed in the images of identical unit cells of the object structure. The electron exposures that result in a significant decrease in the diffraction intensity will depend somewhat upon the resolution (Bragg spacing) involved, and can vary considerably with the chemical makeup and composition of the specimen material.
