Urban dwellers’ food and nutritional wellbeing are both dependent on infrastructure and can be indicative of wider wellbeing in urban contexts and societal health. This paper focuses on the multiple relationships that exist between food and infrastructure to provide a thorough theoretical and empirical grounding to urgent work on urban food security and nutrition in the context of rapid urban and nutrition transitions in the South. We argue that urban systems and food systems thinking have not been well aligned, but (...) that such alignment is not only timely and overdue but also fruitful for both thematic areas of research and policy. We draw in particular on work within wider urban political economy and political ecology that can be classified as part of the ‘infrastructural turn’ that is influential with urban studies but little acknowledged within food studies. Drawing on these literatures helps us to better understand the interrelationships between people, things and ideas that make up both infrastructure and food systems. Policy, planning and research relating to both food and urban systems cannot afford to ignore such interlinkages, though much policy still operates on the neat assumptions of progressive connectivity to ‘the grid’ and formal food retail. Instead we argue how in many urban governance systems, a variety of hybrid mechanisms—on and off the grid, public and private formal and informal—better represent how urban residents, particularly the most marginalised, meet their everyday food and infrastructural needs along a continuum of gridded and off-grid access.

What is a just political order? What does justice require of us? These are perennial questions of political philosophy. John Rawls, generally acknowledged to be one of the most influential political philosophers of the twentieth century, answered them in a way that has drawn widespread attention, not only from political philosophers, but from political scientists, economists, those in the field of public policy, and experts in jurisprudence. It is not only academics who have been inspired by Rawls' ideas; they have (...) also influenced the theory of government and continue to play a role in actual public political debates. This introduction outlines Rawls' work on the theory of justice. Focusing on Rawls' own writings, from his first publication in 1951 to his final ones some fifty years later, Percy B. Lehning demonstrates how and why they can be considered as one consistent and coherent body of work. (shrink)

In 1971, John Rawls published A Theory of Justice, the burden of which was strongly egalitarian. But Rawls eventually came to the conclusion that the project of working out a stable, well‐ordered society as argued in A Theory of Justice had failed. In 1993, in Political Liberalism, Rawls sought to establish a sounder theoretical foundation for a stable, well‐ordered society. Rawls was widely viewed, however, as having given up egalitarianism in Political Liberalism ‐ the commitment to a fair distribution, or (...) ‘justice as fairness’, along lines originally developed in A Theory of Justice. I argue, by contrast, that Political Liberalism does not in fact repudiate the egalitarianism of A Theory of Justice. Political liberalism has many variants, including variant conceptions of justice. In the first part of what follows, the question is raised whether political liberalism can defend a conception of justice that is as egalitarian as ‘justice as fairness’. Such a conception would guarantee the fair value of political liberties and would also contain the so‐called ‘difference principal’, which states that social and economic inequalities are to be adjusted so that they are to the greatest benefit of the least advantaged. Although it seems possible to defend such an egalitarian conception of justice, it does not seem necessary, all the same, that all variants of political liberalism should be as egalitarian as justice as fairness. Thus, in the second part of my argument, I seek to overturn, or at least substantially to qualify, the idea that there is no need for political liberalism to be strongly egalitarian. I conclude that the egalitarian credentials of political liberalism have to be bolstered, even more so than Rawls himself seems to think. (shrink)

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)

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)

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.

Questions of political identity and citizenship, raised by thecreation of the `new Europe', pose new questions that politicaltheorists need to consider. Reflection upon the circumstances ofthe new Europe could help them in their task of delineatingconceptual structures and investigating the character ofpolitical argument.Does it make sense to use concepts as `citizenship' and`identity' beyond the borders of the nation-state? What does itmean when we speak about `European Citizenship' and `EuropeanIdentity'?It is argued that the pluralism that has led theorists tooffer a conception (...) of citizenship based upon principles of right,rather that the common good, applies even more strongly at thelevel of the European political order. Developing a contractariantheory of federation, an account of the basis of a Europeancitizenship will be offered in which federalism emerges out of anoverlapping consensus of European citizens on the terms of theirpolitical association.`European Citizenship' and `European Identity' are discussedin the context of the so-called `European Union', and not in thewider context of Europe `as a whole', or for that matter on aneven broader `cosmopolitan' scale. However, the gist of the articleis that arguments for concepts of `citizenship' and `identity'that go beyond borders of nation-states and that are applied tothe `European Union', could have implications for an even widerapplication.Finally, and in conclusion, the (empirical) context will beelaborated in which the normative concept of shared liberalcitizenship identity should be realized on a pan-national,European level.

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)

El propósito del estudio que generó el presente artículo fue analizar las percepciones de coordinadores y docentes tutores sobre el desarrollo de competencias generales en estudiantes de pregrado desde la acción tutorial. El estudio se realizó según el enfoque cualitativo y diseño fenomenológico, cuya población la constituyeron coordinadores y docentes tutores de estudiantes de pregrado de una Universidad de Lima desde sus experiencias en la acción tutorial. El tamaño de la muestra se determinó por el criterio de saturación. Los datos (...) se recogieron por medio de una guía de encuesta estructurada y el rigor científico se orientó según criterios de calidad: credibilidad, transferibilidad, dependencia y confirmabilidad. Se encontró como resultado principal que la acción tutorial contribuye al desarrollo de algunas competencias genéricas, tales como las comunicativas escritas y orales, y el trabajo en equipo, que son las más valoradas por la experiencia tutorial, ya que se requiere de comunicación fluida.

This draft preprint presents a nine step argument for “Connectionist Structuralism” (CS), an account of the ontology of abstract objects that is neither purely nominalist nor purely platonist. CS is a common, often implicit assumption in parts of the artificial intelligence literature, but such discussions have not presented formal accounts of the position or engaged with metaphysical issues that potentially undermine it. By making the position legible and presenting an initial case for it, we hope to support a constructive dialogue (...) between AI researchers and philosophers of metaphysics that helps both sides to refine the position. -/- CS proposes that each abstract object we can draw on in human analysis corresponds to a particular subset of an individual person’s brain structure whose functionality is isomorphic to a subset of the nodes and connections in a suitable connectionist network. In other words, abstract objects are physically realised, but in individual brains, rather than only in the referent objects (pure nominalism) or in metaphysical universals (pure platonism). -/- This paper’s minimum claim is that CS can account for all abstract object predicables regarding sensible properties, such as “is red” or “is a square”. Using evidence from cognitive neuroscience, machine learning, and evolutionary biology, as well as a fully traceable toy example, we describe how CS can support our core cognitive uses of such sensible properties and can account for our core phenomenal experiences of them. In the former, CS provides sufficient albeit imperfect inferential safety, whose limitations are argued to strengthen rather than weaken the case for CS as describing human behaviour. In the latter, four target phenomenal features are accounted for – abstract objects as feeling intangible, non-located, transparent, and unchanging - along with accounts for further phenomena such as semantic refinement, the Stroop effect, synaesthesia, semantic clarity, sensory overload, and satiation. -/- Our minimum claim concerns the day-to-day usage and felt experience of abstract objects, but we suggest also an extended claim in which CS can form the basis of a pragmatic sufficient logic. As such, the initial outline of a response is provided for five common objections to positions that seek to ground abstract objects without reference to metaphysically stand-alone universals: referential opacity; identity of indiscernibles; infinite regression; non-physical concepts; and necessary truths. These outlines lay the foundation for (but do not seek to formally demonstrate) an extended CS account that addresses other abstract objects, including issues relating to their use in mathematics and formal logic. -/- The CS account leads to a four-layer hierarchy of similarity for whether your “red” is the same as mine. Considering both semantic and phenomenal similarity, we conclude that our “reds” are likely non-identical but can be made close enough for practical purposes. Finally, we describe how future work could elaborate CS as a metaphysical project and how confidence in it could be tested through empirical research. (shrink)

Though I have been a member of this Institute, I think from its foundation, I have been a steadily inactive member, and have resisted with what grace I could the blandishments of our Secretary when he has suggested that I should address my fellow-members. For I am not a philosopher, either by training or, I fear, by instinct; and, now that I have allowed myself to be inveigled into this place, I feel that I am brawling in church. I am (...) the most ill-informed of laymen, and, if you feel any interest at all in what I am about to say, it will, I fear, only be the rueful interest that the expert sometimes takes in an exhibition of ignorance.

Biko was not only considered a 'brilliant political theorist', he is also considered a formidable and articulate philosopher; an important Africana existential philosopher. From Biko's writings, speeches and interviews, Mabogo More's view is that philosophy is not a disembodied system of ideas nor is it a mechanical reflection about the world; rather, it is a way of existing and acting. What Biko himself describes as 'a way of life'. This important perspective on Biko would be of value to many African (...) philosophers, political and social thinkers, social scientists, psychologists, cultural critics, political activists, students, critical race theorists and anyone interested in the ideas that Biko presents.

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)

As this writer reads him, Emerson's thinking falls into three loose and broad categories. He held soul to be divine, that intuition or divine spark within every man, whereby every man is capable of infinite growth. He regarded Nature as the lengthened shadow of God cast upon human sense, a kind of incarnation of some Divine Power here on earth. And he believed Deity ever near to man, and every soul possessed of access to Deity, not continuously, but at least (...) in moments of exaltation. This triple structure--the primacy of the soul, the immediacy of Nature, and Divine Immanence--might be called the skeleton framework of his message. (shrink)
