Now in so far as it is recognized that the constituents of the environment are not present inside the body in the same way as they are present outside it, to that extent they are bound, the moment they are inside it, to become something essentially different from the environment.

In a calculation involving imaginary numbers, we begin with real numbers that represent concrete measures and we end up with numbers that are equally real, but in the course of the operation we find ourselves walking “as if on a bridge that stands on no piles”. How is that possible? How does that work? And what is involved in the as-if stance that this metaphor introduces so beautifully? These are questions that bother Törless deeply. And that Törless is bothered by (...) such questions is a central question for any reader of Törless. Here I offer my interpretation, along with a reconstruction of the philosophical intuition that lies behind it all. (shrink)

Wittgenstein took the _Tractatus Logico-Philosophicus_ to be eventually invalidated by logical atomism. Our main thesis is that it can be revalidated, provided that we subtract the thesis 2.02 (“The object is simple.”) from it: atoms are not simple objects but, rather, bits of information the objects are made of. Starting from an introductory discussion about what is meant by a ‘logic of colors’, an explanatory framework is then proposed in the form of a partition semantics. The philosophical problem of Wittgenstein’s (...) color-statements is reformulated accordingly, thus overcoming the trouble with logical atomism. A Boolean treatment is advanced to solve the initial difficulty and leads to two final results: Wittgenstein’s logic of colors requires a mereological understanding of the relations between colors in order to make sense; the analysis of psychophysical concepts like colors casts some additional doubt about the analytic–synthetic distinction, to the point of treating relations between colors as analytic a posteriori judgments.

Douglas Harding developed a unique first-person experimental approach for investigating consciousness that is still relatively unknown in academia. In this paper, I present a critical dialogue between Harding, Sartre and Merleau-Ponty on the phenomenology of the body and intersubjectivity. Like Sartre and Merleau-Ponty, Harding observes that from the first-person perspective, I cannot see my own head. He points out that visually speaking nothing gets in the way of others. I am radically open to others and the world. Neither does my (...) somatic experience establish a boundary between me and the world. Rather to experience these sensations as part of a bounded, shaped thing (a body), already involves bringing in the perspectives of others. The reader is guided through a series of Harding’s first-person experiments to test these phenomenological claims for themselves. For Sartre, the other’s subjectivity is known through The Look, which makes me into a mere object for them. Merleau-Ponty criticised Sartre for making intersubjective relations primarily ones of conflict. Rather he held that the intentionality of my body is primordially interconnected with that of others’ bodies. We are already situated in a shared social world. For Harding, like Sartre, my consciousness is a form of nothingness; however, in contrast to Sartre, it does not negate the world, but is absolutely united with it. Confrontation is a delusion that comes from imagining that I am behind a face. Rather in lived personal relationships, I become the other. I conclude by arguing that for Harding all self-awareness is a form of other-awareness, and vice versa. (shrink)

The frequent excursions which I have made into this province have all sprung from the profound conviction that the foundations of science as a whole, and of physics in particular, await their next greatest elucidations from the side of biology, and especially, from the analysis of the sensations.Science stands thus in the midst of the natural process of evolution, and she can guide evolution in the proper direction and help it along, but never replace it.A broad foundation is laid for (...) the theory in question, and light is shed upon it from new sides, if, in conformity with the stimulus given by Darwinism, we conceive of all psychical life—including science—as biological appearance, and if we apply to the theory the ..

Nous abordons ici l’étude de la phénoménologie des objets visuels à partir de comptes rendus verbaux, de réponses à des questions ou de descriptions spontanées, ainsi que d’associations libres. Nous demandons même parfois aux sujets de réaliser de simples croquis. Cet éventail de méthodes permet de sonder la structure profonde de la conscience visuelle. Celle-ci est avant tout révélée par ce qui n’est pas spontanément mentionné par des qualités accidentelles ou encore par des changements induits lors de variations ou ajouts (...) mineurs. Nous avons trouvé une concordance remarquable parmi un grand nombre de participants. Ceci démonte que les comptes-rendus verbaux permettent d’explorer puissamment la structure de la conscience visuelle. Tout comme le langage, les « objets visuels simples » ont des racines profondes dans la conscience. Ces fondations « invisibles » servent à définir des figures simples, un « carré » par exemple, comme des objets prototypiques et uniques. La nature des « objets visuels » implique ainsi l’existence d’un « vaste domaine invisible ». Sans une telle prise en compte, la compréhension correcte de la nature de l’objet visuel n’est pas possible. Cette découverte devrait permettre de mener à une théorie de la syntaxe formelle des formes visuelles fondamentales. (shrink)

Ludwig Boltzmann’s Bildtheorie has been portrayed as a pre-cursor of the semantic view of theories and as such, the word “Bild” is translated as model. But this anachronistic understanding of Boltzmann’s use of Bilder fails to account for the wide range of roles they play in his understanding of scientific methodology. When the concept of Bild is understood historically in Viennese thought, a much broader sense emerges that leads to the investigation of its use in multiple ways in various contexts (...) in the process of proposing, pursuing, and justifying scientific beliefs.

We argue that the fundamental assertion underlying Mach's critique of Newton's first law is that inertial motion is not motion in the absence of causes; rather, it is motion whose cause lies in some homogeneous aspect of the environment. We distinguish this formal requirement (Mach's principle) from two hypotheses which Mach considers concerning the origin of inertia: that the distant stars play (1) a merely “collateral” or (2) a “fundamental” role in the causal determination of inertial motion. -/- In his (...) later writings, Mach deliberately avoids referring to the concept of causation, and indeed, this has made the interpretation of Mach's principle a subject of widespread controversy. However, in his earlier writings, the substance of Mach's critique is less ambiguously expressed. Therefore, close attention is given to Mach's early writings and the evolution of his thought. Various accounts in the secondary literature on Mach's principle, in particular those of Norton and DiSalle, are assessed on this basis. We end with a defence of the Machian status and legitimacy of the early Einstein's research program. (shrink)

In this work we discuss the widespread use and application of the notion of 'particle' within the standard understanding of quantum mechanics, trying to prove how it is not just an innocent and unproblematic “way of talking”, as it is often claimed, but the expression of an atomist metaphysics that represents rather a way of perceiving and thinking that inadvertently determines our understanding of the mathematical formalism and the experimental content of quantum mechanics. We show how the retention of atomist (...) concepts, especially due to Bohr’s work, appears not only as an epistemological obstacle but furthermore as an efficient factory of false problems and misleading intuitions that have concentrated the attention of researchers for some time. Revisiting again Heisenberg’s matrix mechanics, we discuss if it would be possible to advance beyond the substantialist account of QM going back to the operational-invariance of intensive quantities.

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)
