This paper is concerned with the reversal in meaning of the word positivism, which has come to mean ‘theory which assumes the existence of a world beyond our ideas’ whereas once it meant ‘theory which is agnostic about the existence of a world beyond our ideas', and with educational writers’ persistent mistakes in using quotation marks, as a consequence of this reversal.

In this paper, I argue for a version of panpsychist idealism on first-person experiential grounds. As things always appear in my field of consciousness, there is prima facie empirical support for idealism. Furthermore, by assuming that all things correspond to a conscious perspective or perspectives (i.e., panpsychism), realism about the world is arguably safeguarded without the need to appeal to God (as per Berkeley’s idealism). Panpsychist idealism also has a phenomenological advantage over traditional panpsychist views as it does not commit (...) perceptual experience to massive error by denying that perceived colours are properties of things. Finally, I argue that the subject combination problem for panpsychism has been motivated by the problematic assumption that consciousness is in things. Thinking about subject combination from the first-person perspective is fruitful for reframing the subject combination problem and for seeing how subjects could potentially combine for the idealist.

In this paper I propose to inquire into the theory of self-awareness propounded by the two Buddhist epistemologists, Dignaga and Dharmakirti. I first give an outline of the Buddhist notion of consciousness, then deal with the notion of objectual appearance, and finally dwell on the theory itself together with certain arguments in its favor. It is shown that the Buddhists subscribed themselves to the following self-awareness thesis: that our waking consciousness is always pre-reflectively and nonconceptually aware of itself. Adopting an (...) approach of interpretive and comparative analysis, I also clarify significant differences between the theory and the correspondent Cartesian views in order to reveal the theory's contemporary relevancy.

Fodor & Pylyshyn (1981) criticize J. J. Gibson's ecological account of perception for failing to address what I call the 'correlation problem' in visual perception. That is, they charge that Gibson cannot explain how perceivers learn to correlate detectable properties of the light with perceptible properties of the environment. Furthermore, they identify the correlation problem as a crucial issue for any theory of visual perception, what I call a 'primary problem'—i.e. a problem which plays a definitive role in establishing the (...) concerns of a particular scientific research program. If they are correct, Gibson's failure to resolve this problem would cast considerable doubt upon his ecological approach to perception. In response, I argue that both Fodor & Pylyshyn's problem itself and their proposed inferential solution embody a significant mistake which needs to be eliminated from our thinking about visual perception. As part of my response, I also suggest a Gibsonian alternative to Fodor & Pylyshyn's primary problem formulation. (shrink)

This paper focuses on the methodological issues related to the obstacles and potential horizons of approaching the philosophical traditions in Islam from the standpoint of comparative studies in philosophy, while also presenting selected case-studies that may potentially illustrate some of the possibilities of renewing the impetus of a philosophical thought that is inspired by Islamic intellectual history. This line of inquiry is divided into two parts: the first deals with questions of methodology, and the second focuses on ontology and phenomenology (...) of perception, by way of offering pathways in investigating the history of philosophical and scientific ideas in Islam from the viewpoint of contemporary debates in philosophy. A special emphasis will be placed on: (a) interpreting the ontology of the eleventh century metaphysician Ibn Sīnā (known in Latin as: Avicenna; d. 1037 CE) in terms of rethinking Heidegger’s critique of the history of metaphysics, and (b) analyzing the philosophical implications of the theory of vision of the eleventh century polymath Ibn al-Haytham (known in Latin as Alhazen; d. ca. 1041 CE) in terms of reflecting on Merleau-Ponty’s phenomenology of perception.

Different explanations of color vision favor different philosophical positions: Computational vision is more compatible with objectivism (the color is in the object), psychophysics and neurophysiology with subjectivism (the color is in the head). Comparative research suggests that an explanation of color must be both experientialist (unlike objectivism) and ecological (unlike subjectivism). Computational vision's emphasis on optimally prespecified features of the environment (i.e., distal properties, independent of the sensory-motor capacities of the animal) is unsatisfactory. Conceiving of visual perception instead as the (...) visual guidance of activity in an environment that is determined largely by that very activity suggests new directions for research. (shrink)

The purpose of this paper is to address some of the questions on the notion of agent and agency in relation to property and personhood. I argue that following the Kantian criticism of Aristotelian metaphysics, contemporary biotechnology and information and communication technologies bring about a new challenge—this time, with regard to the Kantian moral subject understood in the subject’s unique metaphysical qualities of dignity and autonomy. The concept of human dignity underlies the foundation of many democratic systems, particularly in Europe (...) as well as of international treaties, including the Universal Declaration of Human Rights. Digital agents, artificial organisms as well as new capabilities of the human agents related to their embeddedness in digital and biotechnological environments bring about an important transformation of the human self-appraisal. A critical comparative reflection of this transformation is important because of its ethical implications. I deal first with the concept of agent within the framework of Aristotelian philosophy, which is the basis for further theories in accordance with and/or in opposition to it, particularly since modernity. In the second part of this paper, I deal with the concept of personhood in Kantian philosophy, which supersedes the Aristotelian metaphysics of substance and builds the basis of a metaphysics of the moral human subject. In the third part, I discuss the question of artificial agents arising from modern biology and ICT. Blurring the difference between the human and the natural and/or artificial opens a “new space” for philosophical reflection as well as for debate in law and practical policy. (shrink)

This paper advances a novel argument that speech perception is a complex system best understood nonindividualistically and therefore that individualism fails as a general philosophical program for understanding cognition. The argument proceeds in four steps. First, I describe a "replaceability strategy", commonly deployed by individualists, in which one imagines replacing an object with an appropriate surrogate. This strategy conveys the appearance that relata can be substituted without changing the laws that hold within the domain. Second, I advance a "counterfactual test" (...) as an alternative to the replaceability strategy. Third, I show how the typical objects of cross-modal processes (in this case, auditory-visual speech perception), more clearly irreplaceable than the objects of the unimodal process examined by Burge [(1986) Individualism and psychology, The Philosophical Review, XCV, 3-45], supply a firm basis for a nonindividualist interpretation of such cases. Finally, I demonstrate that the routine violation of the individualist's Replaceability Condition occurs even in unimodal cases - so the violation of the replaceability constraint does not derive simply from the diversity of modal sources but rather from the causal complexity of psychological processes generally. The conclusion is that philosophical progress on this issue must await progress in psychology, or, at least, philosophical progress in accounting for psychological complexity--precisely the vicissitude predicted by a thoroughgoing naturalism.

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)

The secondary qualities are those qualities of objects that bear a certain relation to our sensory powers: roughly, they are those qualities that we can readily detect only through a certain distinctive phenomenal experience. Contrary to what is sometimes supposed, there is nothing about the world itself (independent of our minds) that determines the distinction between primary and secondary qualities. Instead, a theory of the secondary qualities must be grounded in facts about how we conceive of these qualities, and ultimately (...) in facts about human perception. (shrink)
