    C. S. Peirce and the Square Root of Minus One: Quaternions and a Complex Approach to Classes of Signs and Categorical Degeneration

    The beginning for C. S. Peirce was the reduction of the traditional categories in a list composed of a fundamental triad: quality, respect and representation. Thus, these three would be named as Firstness, Secondness and Thirdness, as well given the ability to degeneration. Here we show how this degeneration categorical is related to mathematical revolution which Peirce family, especially his father Benjamin Peirce, took part: the advent of quaternions by William Rowan Hamilton, a number system that extends the complex numbers, i.e. those numbers which consists of an imaginary unit built by the square root of minus one. This is a debate that can, and should, have contributions that take into account the role that mathematical analysis and linear algebra had in C. S. Peirce’s past

    On a phaneroscopy beyond human consciousness: Building a phenomenology of multiple realities

    Get PDF
    This essay wants to rescue the concept of phaneroscopy, created by Charles Sanders Peirce, to adapt it in a phenomenological condition of multiple realities. Therefore, in addition to review the reflection of Peirce, we visited the approach of phenomenology of multiple realities proposed by Alfred Schutz in his reading of William James. The idea is to seek a phenomenology that goes beyond the human consciousness to other research subjects

    Phenomenological Tripod: Understanding Phenomenology's Episteme

    Get PDF
    The objective of this research essay is to understand the episteme of phenomenology using the recent construction of Mark D. Vagle which understands phenomenological knowledge as a conceptual tripod between encounters, way of living and crafting. There is here a preliminary view on the subject where it seeks to understand the phenomenology beyond its big names such as Husserl, Heidegger, Merleau-Ponty, Sartre, among others. It is a phenomenology of vision for the twenty-first century, focusing on the epistemological and methodological construction of phenomenological research

    Media Parergon, Media Ergon: An Analytical Overview of the Grammar and Pragmatics of the Media Language

    Get PDF
    The present work has a central question: how a certain media distinguishes itself from the other communicational and linguistic apparatuses of the world. And with that, he turns on the big question of what each media practice would be. The hypothesis defended here is that each type of media, in its definition, is a language and not an apparatus. Using the concepts of Ludwig Wittgenstein, Jacques Derrida, Jean-François Lyotard and John R. Searle, the concepts of parergon and ergon are discussed. Thus, there is the consideration that if the study of the parergon is a logical study, close to the philosophical debates of the Analytical Philosophy and of authors of Continental Philosophy that quoted Wittgenstein, the study of ergon is a pragmatic study, focused on the speech acts. Logic and Pragmatics do not enter here as competitors, but rather as analytical partners in the definition and study of a language. While the first one analyzes the clipping modes, the second analyzes the action made possible by its clipping

    Speed and Sense-Data: Understanding the Senses as Tensors

    Get PDF
    This paper discuss the problem of motion within sense-data concept. Using the sense of speed as starting-point, we debate how it is possible to find a conceptual formulation that combines the idea of mental states with its physicalist criticism. The answer lies in the field of quantum mechanics and its concept of tensor, a geometric object that has a mathematical matrix representation. Thinking about examples taken from the car racing world, where the sense of speed is preponderant, we see how the mental condition of speed is represented matrix-like, tensor-like, rather than ephemerally as the more traditional sense-data formulation advocates

    Efeitos sonoros enquanto fala audiovisual: Análise de Gerald McBoing-Boing à luz do §528 das Investigações Filosóficas

    Get PDF
    Dentro da produção da UPA, estúdio que buscou rivalizar esteticamente com os preceitos da Disney no cinema de animação nos anos 1950, Gerald McBoing-Boing é a personagem mais emblemática, estrelando quatro curtas de animação que representam os preceitos do estúdio. No entanto, o mote narrativo de McBoing-Boing é que ele não se comunica com sons, mas sim por efeitos sonoros, e se fazendo entender. Para entender quais são as possibilidades linguísticas desse uso sonoro e como ele não nos aparece enquanto algo surreal, analisaremos tal representação à luz da segunda filosofia de Ludwig Wittgenstein, cuja obra-chave são as Investigações Filosóficas. Concentrando no §528, o objetivo é mostrar como McBoing-Boing se encaixa em um fenômeno language-like, representando um ponto central na crítica estética da UPA

    Silence in the Coffee Plantation: The Painting-poetics of Candido Portinari

    Get PDF
    This article wants to analyze how Candido Portinari in his paintings with rural theme, engages a poetry of silence. To understand the functioning of this poetic language, we will adopt the Groupe μ analysis method (both the General Rhetoric andthe Treatise on theVisual Sign). Whereas the language is manifold as the forms of representation, and it present in all media, whatever the lack of speech -silence -would find its richest form in both directions through the metaphors and metonymy engaged in metasememes of the paintings studied

    A map for heavy inertial particles in fluid flows

    Full text link
    We introduce a map which reproduces qualitatively many fundamental properties of the dynamics of heavy particles in fluid flows. These include a uniform rate of decrease of volume in phase space, a slow-manifold effective dynamics when the single parameter ss (analogous of the Stokes number) approaches zero, the possibility of fold caustics in the "velocity field", and a minimum, as a function of ss, of the Lyapunov (Kaplan-Yorke) dimension of the attractor where particles accumulate.Comment: 10 pages, 5 figure
