Time in the ontology of Cornelius Castoriadis

We can locate the problematic of time within three philosophical questions, which respectively designate three central areas of philosophical reflection and contemplation. These are: 1) The ontological question, i.e. 'what is being?' 2) The epistemological question, i.e. 'what can we know with certainty?' 3) The existential question, i.e. 'what is the meaning of existence?' These three questions, which are philosophical, but also scientific and political, as they underline the political and moral question of truth and justice, arise from the phenomenon of time, the irreversible constant flow of phenomena that undermines every claim to absolute knowledge. The purpose of this essay is to illuminate the importance of time for philosophical thought and, more generally, for human social and psychical life, in the context of the ontology of Cornelius Castoriadis. Castoriadis, who asserted that " being is time – and not in the horizon of time " , correlated history to society and being to temporality within the social-historical stratum, the ontological plane created by human existence, where " existence is signification ". Time is interpreted as the creation and destruction of forms in a magmatic, layered with a non-regular stratification, reality, where the social-historical manifests as the creation of collective human activity, in the manner of social imaginary significations. This notion of temporality is accompanied by a profound criticism of traditional rationalistic philosophy, to which Castoriadis assigns the name 'ensemblistic/identitary', that highlights the necessity of a new, magmatic ontology, based on the primacy of time

Imagination and Interpretation On the dialogue between Cornelius Castoriadis and Paul Ricoeur

On March 9th, 1985, Paul Ricoeur and Cornelius Castoriadis met at the studio of the France Culture “Le Bon Plaisir” radio broadcaster. In 2016, the transcript of their dialogue, their only public debate, was published. This publication is significant not only because it highlights the points of convergence and divergence between the two prominent thinkers, but also because the issues they discuss: the relation between society and history, tradition and creativity, imagination and collective action, are relevant to the philosophical and political discourse of our time

"The Speech of Dasein: Heidegger and Quotidian Discourse"

In § 35 of Sein und Zeit Heidegger’s denunciation of Gerede, idle talk, is confident and scathing. It sounds so sinister and threatening. What could Heidegger be talking about? One could cite numerous fictional characters (e.g., Pecksniff, Mrs. Gamp, Skimpole, Podsnap – all in Dickens), characters whose speech is very nearly an idiolect of bad faith. And yet there is something so fascinating and creative in their speech, an exuberance in their dissimulation, that one wouldn’t want to miss them. Could idle talk in Heidegger’s sense contribute to the theoretization of Bakhtin's idea of the dialogic and heteroglossia and to the notion of discours as it has been developed by Benveniste, Barthes, and Genette? In prose fiction language is valorized (often implicitly) in terms of meaning/nonsense, serious/non-serious, full/empty. When in fiction language that is deemed low, formulaic, or “empty”-- gossip, chatter, prattle, idiotismes – comes to the fore the narrative elements falters, “nothing much” is said. But a kind of speech as act and process is foregrounded. It is this kind of inadvertence in language, its “idling” state, that Gerede points to

Denotation and connotation in the human-computer interface: The ‘Save as...’ command

This paper presents a semiotic technique as a means of exploring meaning and understanding in interface design and use. This is examined through a study of the interaction between the ‘file’ metaphor and ‘save as’ command metaphor. The behaviour of these (from a functional or computational basis) do not exactly match, or map onto, the meaning of the metaphor. We examine both the denotation of a term to the user, i.e. its literal meaning to that person, and the term’s connotations, i.e. any other meanings associated with the term. We suggest that the technique applied is useful in predicting future problems with understanding the use of metaphor at the interface and with designing appropriate signification for human-computer interaction. Variation in connotation was expected but a more fundamental difference in denotation was also uncovered. Moreover, the results clearly demonstrate that consistency in the denotation of a term is critical in achieving a good user understanding of the command

Chaos and Order in Nature/Creation: A Reading of Genesis l-2:4a in Dialogue with Science and Philosophy

With inspiration from post-modern scientific theories (complexity theory, chaos theory, relativity theory, uncertainty theory, no-singularity/boundary theory), and from philosophical understandings of nature (ecstatic naturalism and Taoism), the author offers an innovative reading of the Genesis creation stories, focusing on the concepts of order and chaos. While criticizing the dichotomous dualism that underpins the human ordering system, she connects these rich meanings and wisdom signified by nature with theological discourse through a discussion of the infinity of God, the abjection of origin, the autonomy of creatures, and nature's complex and fluid manifestations.ye

Plato's Reflections on Phone in Protagoras

One of the issues in regard to any language including classical Greek is phone. But it seems that Plato reflections on this notion are scattered, fragmented, and the like. With regard to this issue, by working on Protagoras dialogue I have tried to explore and explain the word/idea of phone that is used eighteen times in different meanings and significations

The NUHM2 after LHC Run 1

We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, $m^2_{H_{u,d}}$, vary independently from the universal soft SUSY-breaking contributions $m^2_0$ to the masses of squarks and sleptons. Our analysis uses the MultiNest sampling algorithm with over $4 \times 10^8$ points to sample the NUHM2 parameter space. It includes the ATLAS and CMS Higgs mass measurements as well as their searches for supersymmetric jets + MET signals using the full LHC Run~1 data, the measurements of $B_s \to \mu^+ \mu^-$ by LHCb and CMS together with other B-physics observables, electroweak precision observables and the XENON100 and LUX searches for spin-independent dark matter scattering. We find that the preferred regions of the NUHM2 parameter space have negative SUSY-breaking scalar masses squared for squarks and sleptons, $m_0^2 < 0$, as well as $m^2_{H_u} < m^2_{H_d} < 0$. The tension present in the CMSSM and NUHM1 between the supersymmetric interpretation of $g_\mu - 2$ and the absence to date of SUSY at the LHC is not significantly alleviated in the NUHM2. We find that the minimum $\chi^2 = 32.5$ with 21 degrees of freedom (dof) in the NUHM2, to be compared with $\chi^2/{\rm dof} = 35.0/23$ in the CMSSM, and $\chi^2/{\rm dof} = 32.7/22$ in the NUHM1. We find that the one-dimensional likelihood functions for sparticle masses and other observables are similar to those found previously in the CMSSM and NUHM1.Comment: 20 pages latex, 13 figure

Close binary evolution I. The tidally induced shear mixing in rotating binaries

We study how tides in a binary system induce some specific internal shear mixing, able to substantially modify the evolution of close binaries prior to mass transfer. We construct numerical models accounting for tidal interactions, meridional circulation, transport of angular momentum, shears and horizontal turbulence and consider a variety of orbital periods and initial rotation velocities. Depending on orbital periods and rotation velocities, tidal effects may spin down (spin down Case) or spin up (spin up Case) the axial rotation. In both cases, tides may induce a large internal differential rotation. The resulting tidally induced shear mixing (TISM) is so efficient that the internal distributions of angular velocity and chemical elements are greatly influenced. The evolutionary tracks are modified, and in both cases of spin down and spin up, large amounts of nitrogen can be transported to the stellar surfaces before any binary mass transfer. Meridional circulation, when properly treated as an advection, always tends to counteract the tidal interaction, tending to spin up the surface when it is braked down and vice versa. As a consequence, the times needed for the axial angular velocity to become equal to the orbital angular velocity may be larger than given by typical synchronization timescales. Also, due to meridional circulation some differential rotation remains in tidally locked binary systems.Comment: 10 pages, 18 figures, Accepted for publication in Astronomy and Astrophysic
