Throughout his literary career Walker Percy read and studied the philosophical thought of Charles Sanders Peirce in an attempt to re-present in language the world as Percy knew it. Beginning in 1984 and ending in 1990, the year of his death, Percy corresponded with Kenneth Laine Ketner about the "semiotic" of Peirce. Their letters - honest, instructive, and often filled with down-home humor - record an epistolary friendship of two men both passionately interested in Peirce's theory of (...) signs. This volume of letters provides a rich philosophical perspective for better understanding the fiction and nonfiction of Walker Percy. (shrink)

Este texto aborda o paradoxo entre a indústria cultural e a formação humana, com base na teoria crítica. O texto utiliza uma metodologia bibliográfica, discutindo temas como educação, formação, semiformação, indústria cultural, capitalismo e emancipação. O objetivo é debater como a indústria cultural interfere na formação dos indivíduos. A contribuição dos processos educativos para o desenvolvimento da civilização é destacada, enfatizando a importância da criticidade e autorreflexão para evitar a barbárie. Os fundamentos da teoria crítica ressaltam a necessidade de um (...) pensamento filosófico que oriente o sujeito para o esclarecimento. A educação para a emancipação é considerada a mais eficaz para a formação humana em uma sociedade explorada pelo capital. O estudo reconhece que novas questões surgirão, indo além dos limites desta pesquisa. (shrink)

What is the real significance of covariance anyway, and why should it be regarded as so fundamental ? What we mean by a covariant expression is one whose ...

Cyril Scott once described Percy Grainger as a `lovable eccentric'. The Australian-American pianist, composer, ethnologist, and aspiring `all-round man' was, however, more eccentric to his own age than to ours. His views on the environment, food, the body, participatory democracy, and sex all anticipated by several decades views more typical of the mid-late twentieth century. Prolific as a composer, performer, and recording artist, Grainger was an indefatigable writer. This selection of forty-six essays about the production, promotion, and propagation of (...) music is drawn from his over 150 public writings. Written between the turn of the century and the early 1950s, these essays reveal Grainger's youthful compositional plans, his ideas about piano technique, and his enduring high regard for the music of Edvard Grieg, Frederick Delius, and `Frankfurt Group' colleagues Cyril Scott, Roger Quilter, and Henry Balfour Gardiner. Grainger on Music also pursues his evolving thoughts about Nordic music, `Free Music', instrumental usage, and his occasional suggestions for musical development in Australia and the United States.

The “Slicing Problem” is a thought experiment that raises questions for substrate-neutral computational theories of consciousness, including those that specify a certain causal structure for the computation like Integrated Information Theory. The thought experiment uses water-based logic gates to construct a computer in a way that permits cleanly slicing each gate and connection in half, creating two identical computers each instantiating the same computation. The slicing can be reversed and repeated via an on/off switch, without changing the amount of matter (...) in the system. The question is what do different computational theories of consciousness believe is happening to the number and nature of individual conscious units as this switch is toggled. Under a token interpretation, there are now two discrete conscious entities; under a type interpretation, there may remain only one. Both interpretations lead to different implications depending on the adopted theoretical stance. Any route taken either allows mechanisms for “consciousness-multiplying exploits” or requires ambiguous boundaries between conscious entities, raising philosophical and ethical questions for theorists to consider. We discuss resolutions under different theories of consciousness for those unwilling to accept consciousness-multiplying exploits. In particular, we specify three features that may help promising physicalist theories to navigate such thought experiments. (shrink)

The stream of human consciousness appears to be interruptible, in that we can experience a sensation of ‘returning to ourselves after an absence of content’ (e.g. sleep, anaesthesia, full-absorption meditation). Prima facie, such evidence poses a challenge to simple applications of theories of consciousness based on electromagnetic or neural activity in the brain, because some of this activity persists during periods of interruption. This paper elaborates one of several possible responses to the challenge. We build on a previous theory in (...) which EM field topology delineates complex macrophenomenal experience. We first apply an analytic lens to identify different ways in which field topologies might generate sensations of ‘absence of content’. We then test the feasibility of a particular phenomenological approach for assessing those field topologies, powered by the unusual lucidity about cessation pathways induced via certain meditation practices and psychedelic dosages. We build computational simulations of these cessation pathways and test them on eight interviewees with various levels of experience in cessation states. We conclude that this approach can generate usable insight, but requires further formalisation to fulfil its potential. The findings tentatively support our claims but the theory remains speculative at this stage. We set out empirical tests with 11 specific predictions, both for further phenomenological research and for brain manipulation research. Although they align neatly, our ontological and cessation theories can also be separated. The paper describes how our theories can be consistent with other perspectives on consciousness, such as variants of predictive processing or global network theory. (shrink)

Frustration has been growing with mainstay epistemological methods of logical deduction and experimental falsification for assessing theories of consciousness. This paper explores one among several alternatives being proposed: the listed requirements epistemology. A literature search identifies five papers that explicitly list requirements for assessing consciousness theories. These five lists are analysed as a promising starting point, but as yet insufficiently comprehensive to do the method justice. The longest list has 11 items, but 19 unique items are identified across the five (...) lists and a taxonomic analysis by category further surfaces at least 30 potential candidates. Four limitations of the method are discussed, arguing that it is best treated as one practical tool as part of a broader strategy for rigorously assessing consciousness theories and identifying avenues for future research. The conclusion describes a workplan for a sufficiently complete working taxonomy to support the field’s collective endeavours. (shrink)

Implementing an algorithm on part of our causally-interconnected physical environment requires three choices that are typically considered arbitrary, i.e. no single option is innately privileged without invoking an external observer perspective. First, how to delineate one set of local causal relationships from the environment. Second, within this delineation, which inputs and outputs to designate for attention. Third, what meaning to assign to particular states of the designated inputs and outputs. Having explained these types of arbitrariness, we assess their relevance for (...) algorithms from various computational theories of mind (CTM) seeking to account for phenomenal consciousness. Some CTM accounts can survive some of these arbitrariness challenges, but eventually each one examined faces a trilemma. Each is under pressure to dilute at least one of three important CTM desiderata: its causal relevance, its substrate neutrality, or its assignment discrimination (e.g. ability to avoid near-panpsychism). However, unlike previous research, we suggest the debate cannot be fully settled at the level of principle. Certain complex CTM algorithms may be salvageable, albeit not the algorithms specified to date. The paper specifies three areas of investigative work, as well as further theoretical avenues of research, which computationalists may wish to explore to escape the trilemma. (shrink)

In a comprehensive assessment of the penetration of Rawls's ideas in the Netherlands since 1971 five debates are discerned in which different aspects are highlighted or play a role. Some of these debates are more or less ongoing ones, some overlap with each other, and some can be pinpointed more precisely in time. In the first 15 years following the publication of A Theory of Justice, attention was focused on the distributive implications of `justice as fairness'. Next, the `liberalism-communitarianism debate' (...) came to the fore. More recently, Kantian aspects of Rawls's theory have been discussed. A fourth, also more recent debate relates to problems of multiculturalism. Finally, in recent years, and more or less in conjunction with the debate on multiculturalism, the current situation of the Dutch welfare state has been discussed. Here we get back to the core of Rawlsian theory, its distributive implications. But now it is argued that this theory focuses too much on equality at the expense of responsibility and incentives.
