Since Mueller’s 1958 article calling Hegelian dialectics a “legend,” it has been fashionable to deny that Hegel used thesis-antithesis-synthesis dialectics. But in truth, Hegel’s Phenomenology of Spirit has 28 dialectics hidden on four outline levels, and The Philosophy of History has 10 more on three outline levels. In Phenomenology’s macrodialectic, Hegel’s nonsupernatural Spirit–all reality, everything in the universe, including man and artificial objects–advances from unconscious + union (thesis) to conscious + separation (antithesis) to a synthesis of conscious (from the antithesis) (...) + union (from the thesis). Previous interpretations of Phenomenology have missed this dialectic: they have assumed that Spirit’s journey begins with consciousness, whereas the journey actually begins in the primordial state of nature, before man arrives and provides Spirit with its Mind (the collective mind of man). Mind then misperceives itself as a multitude of separate alien “objects”–things other than itself. The macrodialectic and all other dialectics are based on Christianity’s Johannine separation-and-return mythology; all Hegelian dialectics separate from a concept in the thesis, going to that something’s opposite (antithesis), and then return to the thesis concept. Thus, in Hegel’s master-and-slave dialectic (God = master, man = slave), man advances from potential + freedom to actual + bondage (religiosity) to actual + freedom (atheism). Only Marx and Tillich understood Hegelian dialectics. Marx’s basic dialectic (one of four) saw history separating from and returning to Communism, going from communal ownership + poverty (primitive communism, or gens) to private ownership + wealth (slavery, feudalism, capitalism) to communal ownership + wealth (final communism). Tillich’s basic dialectic (one of many) separates from and returns to God, advancing from Yes to God + Yes to supernaturalism (theism) to No to God + No to supernaturalism (atheism) to Yes to God + No to supernaturalism (humanism: humanity is the nonsupernatural “God above the God of theism”).

We present a model for several early stages of the sensorimotor transformations involved in targeted arm movement. In psychophysical experiments, human subjects pointed to the remembered locations of randomly placed targets in three-dimensional space. They made consistent errors in distance, and from these errors stages in the sensorimotor transformation were deduced. When subjects attempted to move the right index finger to a virtual target they consistently undershot the distance of the more distal targets. Other experiments indicated that the error was (...) in the sensorimotor transformation rather than in the perception of distance. The error was most consistent when evaluated using a spherical coordinate system based at the right shoulder, indicating that the neural representation of target parameters is transformed from a retinocentric representation to a shoulder-centered representation. According to the model, the error in distance results from the neural implementation of a linear approximation in the algorithm to transform shoulder-centered target parameters into a set of arm orientations appropriate for placing the finger on the target. The transformation to final arm orientations places visually derived information into a frame of reference where it can readily be combined with kinesthetically derived information about initial arm orientations. The combination of these representations of initial and final arm orientations could give rise to the representation of movement direction recorded in the motor cortex by Georgopoulos and his colleagues. Later stages, such as the transformation from kinematic to dynamic parameters, or to levels of muscle activation, are beyond the scope of the present model. (shrink)

This paper contributes to the foundations of a theory of rational choice for artificial agents in dynamic environments. Our work is developed within a theoretical framework, originally due to Bratman, that models resource-bounded agents as operating against the background of some current set of intentions, which helps to frame their subsequent reasoning. In contrast to the standard theory of rational choice, where options are evaluated in isolation, we therefore provide an analysis of situations in which the options presented to an (...) agent are evaluated against a background context provided by the agent’s current plans—commitments to future activities, which may themselves be only partially specified. The interactions between the new options and the background context can complicate the task of evaluating the option, rendering it either more or less desirable in context than it would have been in isolation.  2001 Elsevier Science B.V.

This collection brings together fourteen contributions by authors from around the globe. Each of the contributions engages with questions about how local and global bioethical issues are made to be comparable, in the hope of redressing basic needs and demands for justice. These works demonstrate the significant conceptual contributions that can be made through feminists' attention to debates in a range of interrelated fields, especially as they formulate appropriate responses to developments in medical technology, global economics, population shifts, and poverty.

Theoretically, a positive environment (PE) includes (a) tangible and intangible resources that satisfy human needs, (b) enablers of healthy, pro-social, and pro-environmental behaviors that guarantee socio-environmental quality and wellbeing, and (c) environmental challenges that must be faced and solved. One of the most salient challenges is the global COVID-19 pandemic. This study sought to investigate whether PEs can stimulate responsible actions (i.e., self-care and precautionary behaviors against COVID-19), while maintaining personal wellbeing. Nine hundred and forty-nine Mexicans participated in an online (...) survey encompassing five primary factors: resources, enablers, challenges, responsible health behaviors, and wellbeing. The first three factors examine “resources” such as physical infrastructure as well as family and social support, “enablers” which include information about protective health practices and perceived legitimacy of authorities in handling the pandemic, and “challenges” encompassing threat perception and social pressure to not engage in precautionary measures. Participants also self-reported hedonic wellbeing as well as self-care and precautionary behaviors, which formed the “responsible (health) behavior” factor. Structural equations model (n= 714 after list-wise deletion) showed that “resources,” “challenges,” and “enablers” form a second-order factor, “positive environments,” and this factor strongly covaries with “responsible behavior” and “wellbeing.” These results suggest that PEs are not only buffers against the negative impact of the COVID-19 pandemic but can also stimulate effective responses against a threat while maintaining individual wellbeing. These results can be used to inform the development and maintenance of PE frameworks aimed at minimizing the spread of COVID-19 and encouraging mental and physical health. (shrink)
