Now available in English for the first time, The Visibility of the Image explores the development of an influential aesthetic tradition through the work of six figures. Analysing their contribution to the progress of formal aesthetics, from its origins in Germany in the 1880s to semiotic interpretations in America a century later, the six chapters cover: Robert Zimmermann (1824-1898), the first to separate aesthetics and metaphysics and approach aesthetics along the lines of formal logic, providing a purely syntactic way of (...) using signs, regardless of objective content; Alois Riegl (1858-1905), who went on to further develop aesthetics on the model of formal logic, creating a theory of style in response to Zimmermann's call for an aesthetics oriented toward formal logic; Heinrich Wölfflin (1864-1945), who represents a step toward an understanding of consciousness by using pictures as cognitive tools; Konrad Fiedler (1841-1895), the Saxon philosopher who considered the possibility that some kinds of images are made and viewed not for what they show, but for their visibility's sake alone; Maurice Merleau-Ponty (1908-1961), responsible for taking up the connections between the problems of reducing the range of potential meanings and contexts of a given image down to just the picture surface; Charles William Morris (1901-1979), who set out to establish whether a picture with no objective reference, such as an abstract painting, still counts as a sign, and if so, in what sense. Bringing these thinkers together and interlinking their ideas, Lambert Wiesing presents an engaging history of formal aesthetics, while reconstructing the philosophical foundations for the appearance of new image forms in the 20th century, including the video-clip, abstract collage, digital simulation and virtual reality. Using this original approach, The Visibility of the Image introduces the rise of modern image theory and provides a valuable account of our engagement with pictures in the 21st century. (shrink)

This essay addresses Cartesian duality and how its implicit dialectic might be repaired using physics and information theory. Our agenda is to describe a key distinction in the physical sciences that may provide a foundation for the distinction between mind and matter, and between sentient and intentional systems. From this perspective, it becomes tenable to talk about the physics of sentience and ‘forces’ that underwrite our beliefs (in the sense of probability distributions represented by our internal states), which may ground (...) our mental states and consciousness. We will refer to this view as Markovian monism, which entails two claims: (1) fundamentally, there is only one type of thing and only one type of irreducible property (hence monism). (2) All systems possessing a Markov blanket have properties that are relevant for understanding the mind and consciousness: if such systems have mental properties, then they have them partly by virtue of possessing a Markov blanket (hence Markovian). Markovian monism rests upon the information geometry of random dynamic systems. In brief, the information geometry induced in any system—whose internal states can be distinguished from external states—must acquire a dual aspect. This dual aspect concerns the (intrinsic) information geometry of the probabilistic evolution of internal states and a separate (extrinsic) information geometry of probabilistic beliefs about external states that are parameterised by internal states. We call these intrinsic (i.e., mechanical, or state-based) and extrinsic (i.e., Markovian, or belief-based) information geometries, respectively. Although these mathematical notions may sound complicated, they are fairly straightforward to handle, and may offer a means through which to frame the origins of consciousness. (shrink)

Whilst the topic of representations is one of the key topics in philosophy of mind, it has only occasionally been noted that representations and representational features may be gradual. Apart from vague allusions, little has been said on what representational gradation amounts to and why it could be explanatorily useful. The aim of this paper is to provide a novel take on gradation of representational features within the neuroscientific framework of predictive processing. More specifically, we provide a gradual account of (...) two features of structural representations: structural similarity and decoupling. We argue that structural similarity can be analysed in terms of two dimensions: number of preserved relations and state space granularity. Both dimensions can take on different values and hence render structural similarity gradual. We further argue that decoupling is gradual in two ways. First, we show that different brain areas are involved in decoupled cognitive processes to a greater or lesser degree depending on the cause (internal or external) of their activity. Second, and more importantly, we show that the degree of decoupling can be further regulated in some brain areas through precision weighting of prediction error. We lastly argue that gradation of decoupling (via precision weighting) and gradation of structural similarity (via state space granularity) are conducive to behavioural success. (shrink)

Model-theoretic proofs of functional completenes along the lines of [McCullough 1971, Journal of Symbolic Logic 36, 15–20] are given for various constructive modal propositional logics with strong negation.

In this paper functional completeness results are obtained for certain positive and constructive propositional logics associated with a Tarski-type structured consequence relation as defined by Gabbay.

Text: Reproduktion nach Scan der Ausgabe von 1934, Verlag von J. C. B. Mohr (Paul Siebeck) in Tübingen. - Von dem kleinen Buch, das ich hier der Öffentlichkeit übergebe, bitte ich den Leser, nichts anderes zu erwarten, als das, was sein Titel ausdrücklich sagt. Es handelt sich in ihm nicht etwa um die Grundlinien eines Systems der Philosophie, sondern ausschließlich um dessen Probleme, und wenn diese sich auch nicht darlegen lassen, ohne die Richtung anzudeuten, in der das System bei der (...) Ausführung sich zu bewegen hätte, so sollen doch in dieser Schrift hauptsächlich Fragen gestellt, nicht Antworten gegeben werden. Oft brechen die Darlegungen dort ab, wo mancher Leser glauben kann, daß die größten Schwierigkeiten noch ungelöst sind. Ja mehr: nur die Grundprobleme der Philosophie werden erörtert, und das Eingehen auf Sonderfragen ist fast überall vermieden. Einzelheiten sind dann allein herangezogen worden, wenn es zur Verdeutlichung der Hauptbegriffe wünschenswert erschien. [Auszug aus dem Vorwort des Buches]. (shrink)

Herophilus, a contemporary of Euclid, practiced medicine in Alexandria in the third century B.C., and seems to have been the first Western scientist to dissect the human body. He made especially impressive contributions to many branches of anatomy and also developed influential views on many other aspects of medicine. Von Staden assembles the fragmentary evidence concerning one of the more important scientists of ancient Greece. Part 1 of the book presents the Greek and Latin texts accompanied by English translation and (...) interpretative commentary. Significant background information is given in the introductory essay preceding each chapter. Part 2 briefly sketches the major developments within the Herophilean school after Herophilus, and discusses the individual members within it. Anyone interested in the history of science, the history of medicine, or intellectual history will find this book a rich source of information about an unusual and important aspect of Greek culture.
