  • Bergson’s Scientific Metaphysics: Matter and Memory Today

    Hirai Y., Bergson’s Scientific Metaphysics: Matter and Memory Today, 2023年01月

    　概要を見る

    This volume brings Bergson’s key ideas from Matter and Memory into dialogue with contemporary themes on memory and time in science, across analytic and continental philosophy. Focusing specifically on the application of Bergson’s ideas to cognitive science, the circuit between perception and memory receives full explication in 15 different essays. By re-reading Bergson through a cognitive lens, the essays provide a series of alternative analytic interpretations to the standard continental approach to Bergson’s oeuvre, without fully discounting either approach. The relevance of philosophies of mind and memory sit alongside the role of a metaphysics of time in exploring connections to psychology, biology, and physics. This eclecticism includes an exciting focus on numerous topics that are not given sufficient attention in extant studies of Bergson, including the precise nature of his ideas on dualism, memory, and ecological theories of perception, especially in relation to his contemporaries. Led by leading Bergson scholars from France and Japan, this book maps the rich terrain of Bergson’s contemporary relevance alongside the historical context of his ideas.

  • System 0/1/2/3: Quad-Process Theory for Multitimescale Embodied Collective Cognitive Systems

    Taniguchi T., Hirai Y., Suzuki M., Murata S., Horii T., Tanaka K.

    Artificial Life 31 （ 4 ） 465 - 496 2025年12月

    ISSN  10645462

    　概要を見る

    This article introduces the System 0/1/2/3 framework as an extension of dual-process theory, employing a quad-process model of cognition. Expanding upon System 1 (fast, intuitive thinking) and System 2 (slow, deliberative thinking), we incorporate System 0, which represents precognitive embodied processes, and System 3, which encompasses collective intelligence and symbol emergence. We contextualize this model within Bergson’s philosophy by adopting multiscale time theory to unify the diverse temporal dynamics of cognition. System 0 emphasizes morphological computation and passive dynamics, illustrating how physical embodiment enables adaptive behavior without explicit neural processing. Systems 1 and 2 are explained from a constructive perspective, incorporating neurodynamical and artificial intelligence (AI) viewpoints. In System 3, we introduce collective predictive coding to explain how societal-level adaptation and symbol emergence operate over extended timescales. This comprehensive framework ranges from rapid embodied reactions to slow-evolving collective intelligence, offering a unified perspective on cognition across multiple timescales, levels of abstraction, and forms of human intelligence. The System 0/1/2/3 model provides a novel theoretical foundation for understanding the interplay between adaptive and cognitive processes, thereby opening new avenues for research in cognitive science, AI, robotics, and collective intelligence.

  • Memory as the origin of the past: a developmental and conceptual refinement of the dependency thesis

    Hirai Y.

    Asian Journal of Philosophy 4 （ 2 ）  2025年12月

    　概要を見る

    This paper aims to refine the dependency thesis, which posits that episodic memory is necessary for acquiring the concept of pastness. By incorporating the hybrid concept thesis, which holds that pastness involves an irreducible experiential component, and the communicability constraint, which states that such experiential content cannot be acquired purely through linguistic or inferential means, this paper argues that pastness cannot be fully explained by relational properties alone. Developmental psychological evidence suggests that temporal cognition progresses in stages, with an early categorical sense of pastness emerging before the ability to structure time sequentially. At this early stage, individuals lack the capacity for time-place indexing, which reinforces the need for direct experiential access in forming the concept of the past. This structured framework clarifies why empirical objections—such as amnesia cases used to challenge the necessity of episodic memory—fail to undermine the dependency thesis. While patients with episodic memory loss retain some relational understanding of time, their concept of pastness remains indirectly dependent on the episodic memory of others. Similarly, critiques arguing that episodic memory is not sufficient for past concept formation conflate different stages of cognitive development, overlooking the necessity of early direct experiential awareness. By integrating philosophical and psychological insights, this paper provides a structured argument for the specific way in which episodic memory contributes to our understanding of time.
