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.

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)

Symbol and existence will prove fascinating to Walker Percy scholars and fans who wish to decipher Percy's authentic philosophical stance. Percy, an existentialist Catholic at his core, was also a scientist seeking an objective paradigm to portray his views. Symbol and existence demonstrates that Percy was quite methodical and logical in his thought and provides an entirely new perspective on his scholarship. Much of this book is unique and has never been published before; however, some sections (...) were revised and published as isolated journal articles or book chapters, never presented as the unified whole that Percy intended. The orderly unity of Percy's work has not previously been accessible to scholars and fans. Symbol and existences systematic presentation and its new material offer fresh insight and a more accurate view of Percy's ideas. His early philosophical writings were often revised and significantly modified by outside editorial intent to conform to prevailing intellectual currents of the time. Readers of some published articles with corresponding passages in Symbol and Existence will be surprised to discover major changes in meaning from Percy's initial writing due to editorial intrusion and loss of context upon their removal from Symbol and existence. As the only known systematic representation of Percy's general working theory, Symbol and existence gives an important framework for his diverse intellectual background--philosophy and psychology, medicine and anthropology, semiotic and zoology--creating a coherent view of Percy's "radical anthropology.

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.

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)

Beschrijving van het leven en gedachtegoed van de Amerikaanse rechtsfilosoof John Rawls, die in zijn werk een filosofisch concept uitwerkte van een samenleving waarin vrijheid en gelijkheid beide tot hun recht zouden komen.

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)

Although Polanyi regards technological knowledge as inferior to scientific knowledge, he uses the idea of machine-like operational principles as an analogy for both his epistemology and his ontology. Since his epistemology is based on personal knowledge, this suggest the need for a personal ontology. Polanyi tries to avoid such a conclusion by invoking impersonal evolutionary factors.
