  Can Time Exist Without Change?

  Fabio Llorella Costa, Aug. 5, 2026Can Time Pass When Absolutely No Change Occurs? This question, which lies at the heart of Sydney Shoemaker’s famous thought experiment, invites us to distinguish the measurement of time from its very nature. By revisiting this argument, Fabio R. Llorella Costa suggests that the hypothesis of “time without change” may already presuppose what it claims to prove. A clear and rigorous reflection leading from logical analysis to a genuinely ontological inquiry into the nature of becoming.

  An Interview with Sylvie Paillat: The Metaphysics of Laughter

  Sylvie Paillat, Jul. 27, 2026Why has laughter occupied such a marginal place in the history of philosophy when it may well reveal one of the deepest dimensions of human existence? In this interview, Sylvie Paillat presents the central insights of her work The Metaphysics of Laughter. She argues that laughter, far from being merely a psychological or social phenomenon, can become a privileged avenue toward the great metaphysical questions: Being, consciousness, finitude, transcendence, and the meaning of the Logos. An original reflection that invites us to rethink philosophy itself in the light of a truly “metaphysical laughter.”

  AI, artificial mental energy, unintelligent by nature

  Bruno Bérard, Jun. 21, 2026Machines calculate, but do they understand? Based on the fundamental distinction between reason and intelligence—a distinction overlooked by much of modern thought—this article argues that the term “artificial intelligence” is a misnomer. Current systems do not think, do not understand, and are not free; they harness a new power of computation and simulation. From Kant to Turing, from Leibniz to Jean Borella, this reflection sheds new light on the debates surrounding AI, its dangers, its promises, its energy costs, and its impact on the future of human societies.

  Descartes the Metaphysician

  Françoise Pochon-Wesolek, Jun. 16, 2026How should Cartesian philosophy be approached? It is important to emphasize, throughout Descartes’ intellectual journey, the essential role of evidence (évidence), which must be distinguished from mere certainty. It is the indubitability of evidence that enables Descartes to discover the Cogito and to formulate the various “proofs” of God’s existence. Evidence is not a demonstrative procedure that constructs its object; rather, it is an immediate experience of thought through which the mind necessarily submits to a given intellectual content. Consequently, interpretations that reduce Descartes’ philosophy to an onto-theology or to a merely pre-critical enterprise ought to be challenged. One may thus speak of a genuine Cartesian metaphysics, a metaphysics whose inspiration can, in many respects, be traced back to Platonic thought.

  Metaphilosophy: The Three Modes of Philosophizing

  Bruno Bérard, Jun. 4, 2026What does it mean to philosophize? To seek the truth, to contemplate it, or to formulate it? Drawing on an insight of Jean Borella, this article argues that the philosophical act comprises three inseparable dimensions: interrogation, contemplation, and formulation. Every great philosophy is shaped by the tension among these three modes, sometimes privileging one at the expense of the others. Such a perspective opens the way to a genuine metaphilosophy: no longer a particular doctrine, but a reflection on the very nature of philosophizing itself.
