Early Greek Thought and Perspectives for the Interpretation of Quantum Mechanics: Preliminaries to an Ontological Approach
It will be shown in this article that an ontological approach for some
problems related to the interpretation of Quantum Mechanics could emerge from a
re-evaluation of the main paradox of early Greek thought: the paradox of Being
and non-Being, and the solutions presented to it by Plato and Aristotle.
Plato's and Aristotle's systems are argued here to do on the ontological level
essentially the same: to introduce stability in the world by introducing the
notion of a separable, stable object, for which a principle of contradiction is
valid: an object cannot be and not-be at the same place at the same time. After
leaving Aristotelian metaphysics, early modern science had to cope with these
problems: it did so by introducing ``space'' as the seat of stability, and
``time'' as the theater of motion. But the ontological structure present in
this solution remained the same. Therefore the fundamental notion `separable
system', related to the notions observation and measurement, themselves related
to the modern concepts of space and time, appears to be intrinsically
problematic, because it is inextricably connected to classical logic on the
ontological level. We see therefore the problems dealt with by quantum logic
not as merely formal, and the problem of `non-locality' as related to it,
indicating the need to re-think the notions `system', `entity', as well as the
implications of the operation `measurement', which is seen here as an
application of classical logic (including its ontological consequences) on the
material world.Comment: 18 page
The enigma of Vitruvian resonating vases and the relevance of the concept for today
The clarity of sound within Greek or Roman theatres (without any form of enhancement) will be impressive to any visitor. The seats arranged in curved rows around the circular orchestra form large horizontal reflecting surfaces. The paths of sound waves travel from the source (the actor or singer) to each of the listeners in a direct path (i.e. without obstruction or reflection). Vitruvius, however, claimed further enhancements could be made. In theatres, also, are copper vases and these are placed in chambers under the rows of seats in accordance with mathematical reckoning. The Greeks call them Echeia. The differences of the sounds which arise are combined into musical symphonies... ⊠it becomes fuller, and reaches the audience with a richer and sweeter note. Vitruvius, on Architecture, Book I, â on training of architects, Loeb This paper explores the notion of intent and purpose behind the Vitruvian concept and also addresses an arguably more complex issue, that of a potential fusion between archaeology, science and art.Peer reviewe

'Secure, anonymous, unregulated': 'Cryptonomicon' and the transnational data haven
This essay considers how Neal Stephensonâs 1999 epic novel Cryptonomicon engages with the long-standing and complex relationship between cryptology and national/transnational identity. Cryptonomicon's layered and disjointed structure allows it to explore the impact of cryptography and cryptanalysis in the Second World War (as well as their impact on the consequent rewriting of the international political stage), to reflect on the place of technology in the recent history of cryptology, and to consider how emergent (and supposedly secure) data storage technologies not only open up planetary-wide communication traffic but also unsettle the agreed protocols of national and international law. Stephenson provides a sense of technology's global effects by offering not a straightforward narrative of the demise of the nation-state but by showing how technologies are in a process of constant negotiation with the institutions of the nation-state, drawing upon the economic, material, and intellectual resources of the nation state, while at the same time challenging notions of a bordered and coherent national identity and working to disestablish nations of their regulatory authority. The essay is informed by recent work on cryptology, data havens, globalization, transnationalism, and postcoloniality, as well as Derrida's work on archives and technology
Beyond Desartes and Newton: Recovering life and humanity
Attempts to ânaturalizeâ phenomenology challenge both traditional phenomenology and traditional approaches to cognitive science. They challenge Edmund Husserlâs rejection of naturalism and his attempt to establish phenomenology as a foundational transcendental discipline, and they challenge efforts to explain cognition through mainstream science. While appearing to be a retreat from the bold claims made for phenomenology, it is really its triumph. Naturalized phenomenology is spearheading a successful challenge to the heritage of Cartesian dualism. This converges with the reaction against Cartesian thought within science itself. Descartes divided the universe between res cogitans, thinking substances, and res extensa, the mechanical world. The latter won with Newton and we have, in most of objective science since, literally lost our mind, hence our humanity. Despite Darwin, biologists remain children of Newton, and dream of a grand theory that is epistemologically complete and would allow lawful entailment of the evolution of the biosphere. This dream is no longer tenable. We now have to recognize that science and scientists are within and part of the world we are striving to comprehend, as proponents of endophysics have argued, and that physics, biology and mathematics have to be reconceived accordingly. Interpreting quantum mechanics from this perspective is shown to both illuminate conscious experience and reveal new paths for its further development. In biology we must now justify the use of the word âfunctionâ. As we shall see, we cannot prestate the ever new biological functions that arise and constitute the very phase space of evolution. Hence, we cannot mathematize the detailed becoming of the biosphere, nor write differential equations for functional variables we do not know ahead of time, nor integrate those equations, so no laws âentailâ evolution. The dream of a grand theory fails. In place of entailing laws, a post-entailing law explanatory framework is proposed in which Actuals arise in evolution that constitute new boundary conditions that are enabling constraints that create new, typically unprestatable, Adjacent Possible opportunities for further evolution, in which new Actuals arise, in a persistent becoming. Evolution flows into a typically unprestatable succession of Adjacent Possibles. Given the concept of function, the concept of functional closure of an organism making a living in its world, becomes central. Implications for patterns in evolution include historical reconstruction, and statistical laws such as the distribution of extinction events, or species per genus, and the use of formal cause, not efficient cause, laws
Deconfabulation: Agamben's Italian Categories and the Impossibility of Experience
Agambenâs self-professed epigonism underwrites his entire project, serving as an even more fundamental methodological concept than the signature, paradigm, and archeology. In Infancy and History, Agamben maintains that transcendental experience is no longer a viable source of philosophical insight; philosophers go astray referring their thinking back to an authentic yet esoteric experience that, itself unspeakable, grounds positive philosophical assertions. Neither mysterious nor ineffable, the experience founding philosophy is the completely patent, non-latent, experience of language's pure exteriority. Rather than âdeconstructingâ metaphysics by exposing its hidden contradictions, philosophy must "deconfabulate," telling fables about philosophy to undo its enchantments, since it is through the fable that the spell of silence, which itself originates in fable, can be broken. This "epigonal" method, which follows after the tradition rather than seeking a new grounding, is itself justified through Agambenâs account, in The End of the Poem, of the Italian, as opposed to Germanic, physiognomy and of a specifically Italian relation to language going back to Dante. To be Italian is to embrace the âdeadnessâ of oneâs own language, rejecting the myth of the resurrection of the original potencies of a dead classical language through a living, modern language
Replicate after reading : on the extraction and evocation of cultural information
Does cultural evolution happen by a process of copying or replication? And how exactly does cultural transmission compare with that paradigmatic case of replication, the copying of DNA in living cells? Theorists of cultural evolution are divided on these issues. The most important objection to the replication model has been leveled by Dan Sperber and his colleagues. Cultural transmission, they argue, is almost always reconstructive and transformative, while strict 'replication' can be seen as a rare limiting case at most. By means of some thought experiments and intuition pumps, I clear up some confusion about what qualifies as 'replication'. I propose a distinction between evocation and extraction of cultural information, applying these concepts at different levels of resolution. I defend a purely abstract and information-theoretical definition of replication, while rejecting more material conceptions. In the end, even after taking Sperber's valuable and important points on board, the notion of cultural replication remains a valid and useful one. This is fortunate, because we need it for certain explanatory projects (e.g., understanding cumulative cultural adaptations)
Multi-algorithmic Cryptography using Deterministic Chaos with Applications to Mobile Communications
In this extended paper, we present an overview of the principal issues associated with cryptography, providing historically significant examples for illustrative purposes as part of a short tutorial for readers that are not familiar with the subject matter. This is used to introduce the role that nonlinear dynamics and chaos play in the design of encryption engines which utilize different types of Iteration Function Systems (IFS). The design of such encryption engines requires that they conform to the principles associated with diffusion and confusion for generating ciphers that are of a maximum entropy type. For this reason, the role of confusion and diffusion in cryptography is discussed giving a design guide to the construction of ciphers that are based on the use of IFS. We then present the background and operating framework associated with a new product - CrypsticTM - which is based on the application of multi-algorithmic IFS to design encryption engines mounted on a USB memory stick using both disinformation and obfuscation to âhideâ a forensically inert application. The protocols and procedures associated with the use of this product are also briefly discussed
Reassessing Neo-Kantianism. Another Look at Hermann Cohenâs Kant Interpretation
This article is a novel assessment of Hermann
Cohenâs theoretical philosophy, starting out
from his Kant interpretation. Hermann Cohen was
the head and founder of the Marburg School of Neo-
Kantianism. In the beginning, hence, I will commence
with some initial reflections on the makeup and
importance of this school, before I move on to Cohenâs
revolutionary Kant interpretation and its ramification
for the Marburg School in general
