  2. Illusionism and Definitions of Phenomenal Consciousness.Takuya Niikawa - 2020 - Philosophical Studies (1):1-21.
    This paper aims to uncover where the disagreement between illusionism and anti-illusionism about phenomenal consciousness lies fundamentally. While illusionists claim that phenomenal consciousness does not exist, many philosophers of mind regard illusionism as ridiculous, stating that the existence of phenomenal consciousness cannot be reasonably doubted. The question is, why does such a radical disagreement occur? To address this question, I list various characterisations of the term “phenomenal consciousness”: (1) the what-it-is-like locution, (2) inner ostension, (3) thought experiments such as philosophical (...)

    Classification of Disjunctivism About the Phenomenology of Visual Experience.Takuya Niikawa - 2019 - Journal of Philosophical Research 44:89-110.
    This paper proposes a classificatory framework for disjunctivism about the phenomenology of visual perceptual experience. Disjunctivism of this sort is typically divided into positive and negative disjunctivism. This distinction successfully reflects the disagreement amongst disjunctivists regarding the explanatory status of the introspective indiscriminability of veridical perception and hallucination. However, it is unsatisfactory in two respects. First, it cannot accommodate eliminativism about the phenomenology of hallucination. Second, the class of positive disjunctivism is too coarse-grained to provide an informative overview of the (...)

    A Challenge to the Phenomenal Sufficiency Thesis.Takuya Niikawa & Yasushi Ogusa - 2022 - Asian Journal of Philosophy 1 (1).
    Smithies defends the phenomenal sufficiency thesis, according to which every perceptual experience provides immediate, defeasible justification to believe some content in virtue of its phenomenal character alone. This commentary challenges this thesis by presenting two kinds of knowledge, the possession of which seems necessary for perceptual justification.

    Human Brain Organoids and Consciousness.Takuya Niikawa, Yoshiyuki Hayashi, Joshua Shepherd & Tsutomu Sawai - 2022 - Neuroethics 15 (1):1-16.
    This article proposes a methodological schema for engaging in a productive discussion of ethical issues regarding human brain organoids, which are three-dimensional cortical neural tissues created using human pluripotent stem cells. Although moral consideration of HBOs significantly involves the possibility that they have consciousness, there is no widely accepted procedure to determine whether HBOs are conscious. Given that this is the case, it has been argued that we should adopt a precautionary principle about consciousness according to which, if we are (...)

    Functions of Consciousness: Conceptual Clarification.Takuya Niikawa, Katsunori Miyahara, Hiro Taiyo Hamada & Satoshi Nishida - 2022 - Neuroscience of Consciousness 2022 (1).
    There are many theories of the functions of consciousness. How these theories relate to each other, how we should assess them, and whether any integration of them is possible are all issues that remain unclear. To contribute to a solution, this paper offers a conceptual framework to clarify the theories of the functions of consciousness. This framework consists of three dimensions: (i) target, (ii) explanatory order, and (iii) necessity/sufficiency. The first dimension, target, clarifies each theory in terms of the kind (...)

    Naïve Realism and Phenomenal Intentionality.Takuya Niikawa - 2020 - Philosophia 49 (3):1127-1143.
    This paper argues for the conjunctive thesis of naïve realism and phenomenal intentionalism about perceptual experiences. Naïve realism holds that the phenomenology of veridical perceptual experience is constituted by environmental objects that the subject perceives. Phenomenal intentionalism about perceptual experience states that perceptual experience has intentionality in virtue of its phenomenology. I first argue that naïve realism is not incompatible with phenomenal intentionalism. I then argue that phenomenal intentionalists can handle two objections to it by adopting naïve realism: the first (...)

    A Map of Consciousness Studies: Questions and Approaches.Takuya Niikawa - 2020 - Frontiers in Psychology 11.
    This article aims to present a map of consciousness studies, which consists of a list of fundamental questions about consciousness and existing approaches to them. The question list includes five fundamental categories: Definitional, Phenomenological, Epistemological, Ontological, and Axiological. Each fundamental category is divided into more determinate questions. Existing approaches to each question are also classified into a few groups, presenting principal researchers who take each kind of approach. In the final section, I demonstrate the usefulness of the proposed map of (...)

    Naïve Realism and the Conception of Hallucination as Non-Sensory Phenomena.Takuya Niikawa - 2017 - Disputatio 9 (46):353-381.
    In defence of naïve realism, Fish has advocated an eliminativist view of hallucination, according to which hallucinations lack visual phenomenology. Logue, and Dokic and Martin, respectively, have developed the eliminativist view in different manners. Logue claims that hallucination is a non-phenomenal, perceptual representational state. Dokic and Martin maintain that hallucinations consist in the confusion of monitoring mechanisms, which generates an affective feeling in the hallucinating subject. This paper aims to critically examine these views of hallucination. By doing so, I shall (...)

    A New Experimental Phenomenological Method to Explore the Subjective Features of Psychological Phenomena: Its Application to Binocular Rivalry.Takuya Niikawa, Katsunori Miyahara, Nishida Satoshi & Hamada Hiro Taiyo - 2020 - Neuroscience of Consciousness 2020 (1).
    The subjective features of psychological phenomena have been studied intensively in experimental science in recent years. Although various methods have been proposed to identify subjective features of psychological phenomena, there are elusive subjective features such as the spatiotemporal structure of experience, which are difficult to capture without some additional methodological tools. We propose a new experimental method to address this challenge, which we call the contrast-based experimental phenomenological method (CEP). CEP proceeds in four steps: (i) front-loading phenomenology, (ii) online second-personal (...)

    The Realizations of the Self.Andrea Altobrando, Takuya Niikawa & Richard Stone (eds.) - 2018 - Palgrave MacMillan.
    Recent discussions of self-realization have devolved into unscientific theories of self-help. However, this vague and often misused concept is connected to many important individual and social problems. As long as its meaning remains unclear, it can be abused for social, political, and commercial malpractices. To combat this issue, this book shares perspectives from scholars of various philosophical traditions. Each chapter takes new steps in asking what the meaning of self-realization is–both in terms of what it means to understand who or (...)

    Within the history of philosophy and across different cultures, few questions have been raised as frequently as what the realization of oneself means. Certainly, one of the very driving forces of philosophy seems to be the clarification of the self and its life. However, in spite of this, within recent years, there have been few serious critical and philosophical efforts to discuss what exactly it means to realize oneself. To this degree, there is a need to critically assess the meaning (...)
