Naïve Realism and Phenomenal Intentionality
This paper argues for the conjunctive thesis of naive realism and phenomenal intentionalism about perceptual experiences. Naive realism holds that the phenomenology of veridical perceptual experience is (at least in part) 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 naive realism is not incompatible with phenomenal intentionalism. I then argue that phenomenal intentionalists can handle two objections to it by adopting naive realism: the first objection is that phenomenal intentionalism cannot explain how a veridical perceptual experience is directed at a particular object rather than any other object of the same kind. The second objection is that phenomenal intentionalism cannot explain how a perceptual experience is directed at a type of external object rather than other types of objects without appealing to a resemblance relation between a perceptual experience and an external object, which is considered to be problematic
Consciousness is Sublime
Does consciousness have non-instrumental aesthetic value? This paper answers this question affirmatively by arguing that consciousness is sublime. The argument consists of three premises. (1) An awe experience of an object provides prima facie justification to believe that the object is sublime. (2) I have an awe experience about consciousness through introspecting three features of consciousness, namely the mystery of consciousness, the connection between consciousness and well-being, and the phenomenological complexity of consciousness. (3) There is no good defeater of the justificatory force of my feeling of awe for the sublime of consciousness. To defend the third premise, I argue against two potential defeaters: The first is that most people do not regard consciousness as sublime. The second is that there do not seem to be physical properties that can ground the sublimity of consciousness. I conclude by emphasizing an important ethical implication of the thesis that consciousness is sublime, namely that it explains why even conscious subjects who cannot have valenced experiences deserve moral consideration
Human Brain Organoids and Consciousness
ヒト脳オルガノイドがもちうる意識の問題を検討し、研究上の倫理的枠組みを提案. 京都大学プレスリリース. 2022-02-17.The ethics of research on conscious artificial brains. 京都大学プレスリリース. 2022-02-18.This article proposes a methodological schema for engaging in a productive discussion of ethical issues regarding human brain organoids (HBOs), 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 not certain whether HBOs have consciousness—and where treating HBOs as not having consciousness may cause harm to them—we should proceed as if they do have consciousness. This article emphasizes a methodological advantage of adopting the precautionary principle: it enables us to sidestep the question of whether HBOs have consciousness (the whether-question) and, instead, directly address the question of what kinds of conscious experiences HBOs can have (the what-kind-question), where the what-kind-question is more tractable than the whether-question. By addressing the what-kind-question (and, in particular, the question of what kinds of valenced experiences HBOs can have), we will be able to examine how much moral consideration HBOs deserve. With this in mind, this article confronts the what-kind-question with the assistance of experimental studies of consciousness and suggests an ethical framework which supports restricting the creation and use of HBOs in bioscience
The Sublime of Consciousness
The aesthetic tradition has identified as paradigmatically sublime such objects as imposing mountains and intense storms, as well as monumental art. But the tradition also acknowledges less paradigmatic cases, including sometimes mathematical structures or abstract concepts. In this paper, we argue that there is also a case for considering phenomenal consciousness – the experiential quality of subjective awareness – as a sublime phenomenon. One appreciates this, we argue, when one is struck by (fitting) awe upon contemplating (a) the perplexing existence of something like phenomenal consciousness in an otherwise completely material universe and (b) the role of consciousness in injecting meaning and value in an otherwise brutally factual reality
Mapping the Ethical Issues of Brain Organoid Research and Application
脳オルガノイドの研究と臨床応用での倫理問題を体系化. 京都大学プレスリリース. 2021-04-07.Society is not ready to make human brains. 京都大学プレスリリース. 2021-03-26.In 2008, researchers created human three-dimensional neural tissue – known as the pioneering work of “brain organoids.” In recent years, some researchers have transplanted human brain organoids into animal brains for applicational purposes. With these experiments have come many ethical concerns. It is thus an urgent task to clarify what is ethically permissible and impermissible in brain organoid research. This paper seeks (1) to sort out the ethical issues related to brain organoid research and application and (2) to propose future directions for additional ethical consideration and policy debates in the field. Toward (1), this paper first outlines the current state of brain organoid research, and then briefly responds to previously raised related ethical concerns. Looking next at anticipated scientific developments in brain organoid research, we will discuss (i) ethical issues related to in vitro brain organoids, (ii) ethical issues raised when brain organoids form complexes or have relationships with other entities, and (iii) ethical issues of research ethics and governance. Finally, in pursuit of (2), we propose research policies that are mindful of the ethics of brain organoid research and application and also suggest the need for an international framework for research and application of brain organoids
