: In APo II 3-7 Aristotle discusses a series of difficulties concerning definition, deduction, and demonstration. In this paper I focus on two interrelated but distinct questions: firstly, what are exactly the difficulties emerging from or alluded to in the discussion in II 3-7; secondly, whether and in what sense the discussion in II 3-7 can be considered an aporetic discussion with a specific role to play in the development of the argument in APo II.

The article focuses on Galileo's Letter to Castelli, 21 December 1613. The author analyzes Galileo's hermeneutical principles established in the first part of the letter and his literal interpretation of the passage from the Book of Joshua 10, 12-13, in Copernican terms, in the second part of the letter. Galileo appears to use the Bible as a scientific authority, supporting his Copernican views, and thus he seems to contradict his own hermeneutical principles. The author argues that Galileo's position is (...) consistent, especially if one takes into account the historical context of its genesis, that is, in the context of the constant, theologically-inspired attacks on Copernicus and Galileo and his commitment to the heliocentric world system and in the context of his newly-made telescopic observations and discoveries.

This paper explores the deep philosophical affinities between Martin Heidegger and Friedrich Nietzsche, focusing on their shared understanding of the Apollonian and Dionysian dichotomy and its implications for the essence of human existence. The analysis begins by examining Nietzsche's concept of the unity of the Apollonian and Dionysian as a fundamental aspect of human identity, despite Nietzsche's own unawareness of its metaphysical significance. Heidegger, in turn, recognizes this insight as an epochal breakthrough in Nietzsche's thought, surpassing the boundaries of traditional (...) meta-physics. The discussion further explores the role of Hölderlin as a crucial figure in both Nietzsche's and Heidegger's philosophical trajectories. It argues that in the co-appropriation of the Apollonian and Dionysian and the concept of Ereignis (the Event), both philosophers reveal a profound engagement with the interplay of foundation and abyss. This interplay, according to Heidegger, constitutes the historical-epochal opening of being and provides a perspective for understanding the essence of Dasein as the Ek-sistence (existential being). The paper challenges Heidegger's reductionist interpretation of Nietzsche as merely the completion of metaphysics and suggests a closer affinity between Nietzsche and Hölderlin. It concludes by emphasizing the transformative potential of embracing the interplay of the Apollonian and Dionysian and the reevaluation of human essence based on existence, which enables a new understanding of the world and its inherent mysteries.

After more than two millennia of theorizing, a unified view of how laughter works is still lacking. Over the years, philosophers have proposed three predominant hypotheses to explain this peculiar human behavior, based on a feeling of superiority, the appreciation of something that violates our expectations, or the release of nervous energy. Contemporary affective neuroscience inherited these frameworks, attempting to parcellate the brain regions involved in laughter production accordingly. In the present paper, I will discuss a fourth hypothesis, suggesting that (...) laughter is, first and foremost, a mean for social bonding and communication, evolved to change the behavior of others. Such ‘social-interaction hypothesis’, which links the emotional aspect of laughter to social action tendencies, is in line with a longstanding tradition that goes back to the early Dewey and Mead’s theories of emotion, and the best equipped to explain new evidence from affective neuroscience.

This article delves into the mature philosophy of Leibniz, exploring his concepts of life and organism. It aims to establish links between the scientific discoveries of the 17th century and Leibnizian metaphysical assumptions. The paper also highlights how reflections on the Cudworthian system helped the Leipzig philosopher develop his «metaphysics of the organics». The article begins with a brief overview of the querelle sur les natures plastiques to deepen some Leibnizian positions on these topics. It emphasizes Leibniz’s focus on the (...) concept of organism and its fundamental relation and difference with the concept of life. The article also addresses the notion of «nested individuality» and plural individuality in the philosopher’s writings, attempting to determine if such concepts exist. The solution to the coexistence of plural organisms within an organism provided here is mereological. Lastly, the article gathers current research results to demonstrate how the «organism» in the Leibnizian system of maturity is like a fold, leading readers toward different aspects of his metaphysics.
