    This article is the text of a Plenary Session lecture presented at the World Congress of Philosophy, Rome, 2024. In it I argue that archaeological evidence shows that the first written philosophy originated not in Greece, India, or China as is commonly believed, but, in Sumer, Mesopotamia, approximately 2600 BCE. The author, En Hedu’Anna, was a woman. I describe four writings by her, distinguish her views from then-prevailing Mesopotamian views about a variety of philosophic concepts and topics.…Read more

  • This text provides a dual portrait of two Croatian women philosophers, Elza Kučera and Ivana Rossi, who were related to each other, by exploring their contributions to philosophy and psychology. Kučera’s opus is far more extensive than Rossi’s: while Kučera left behind around 13,000 papers, Rossi’s output is limited to a doctoral dissertation, a short academic text, and a translation. Methodologically, Kučera followed a combination of philosophical concept analysis with experimental approach inf…Read more
  • Three nuns from the Jansenist convent of Port-Royal illustrate the type of philosophical reflection which can emerge within a theological itinerary. Jacqueline Pascal (1615–1661) sketches the philosophy of education which guided the convent school she directed. The teaching nun exercises authority as the theologian and spiritual director for the students she meets in periodic tutorials. Agnès Arnauld (1593–1672) analyzes the moral virtues which the nun must cultivate in terms of her fundamental …Read more

    Both Antoinette Brown-Blackwell and Mary Whiton Calkins pursued an interest in the metaphysical nature of individuality and the self. Their perspectives, however, differed greatly: while Calkins’s perspective was influenced by psychology, Brown-Blackwell’s was influenced by physics. What formed the theoretical basis of their perspectives also differed: for Brown-Blackwell energy is what is ultimate in the universe, God being energy itself; for Calkins absolute personalism is what is ultimate in …Read more
  • This article is a brief introduction and overview of my research project on Donna J. Haraway. The aim of this project is to examine how existing boundaries can be dissolved and address grievances in science and research. These grievances impact the image of society and the body and can be clearly located in patriarchal culture. To this end, the work of the American biologist and philosopher Donna J. Haraway will be examined, and examples of deconstructing scientific objects will be sought that q…Read more
  • This article compares Arendt’s and Aquinas’ views on thinking and willing, in order to prepare the ground for a comparison of their respective understandings of judging and justice. It takes its point of departure in Arendt’s attention to Aquinas in her last unfinished work, The Life of the Mind. Contrary to expectations, Arendt’s rejection of the ‘two-world theory’ does not inform her dealings with Aquinas directly. Far from criticising his metaphysics, she expresses admiration for his metaphys…Read more

This project greatly advanced the recognition of the hi…Read more
  • Helle Lambridis (1896–1970) was a philosopher from Greece whose work spans various philosophical fields. This paper focuses on her moral-political philosophy, specifically her theory of justice for the state, as unfolded in the final chapter of her unfinished posthumous work Fantasia Philosophica (Λαμπρίδη, Ακαδημία Αθηνών, Κέντρον Ερεύνης της Ελληνικής Φιλοσοφίας, 2021). In this chapter, among others, Lambridis defends the moral principle of the survival of the human species as the basis for ad…Read more
  • Stein uses the language of ‘soul’ (Seele, seelisch) in numerous different ways within her philosophical corpus, drawing at differing times from ways of speaking of soul that are more common in phenomenological, metaphysical, theological, and mystical traditions. This essay argues that whenever Stein uses ‘soul’ in ways that appear analogous to more metaphysical conversations (e.g., a Platonic or Aristotelian vision of soul), Stein is not referring to soul as a distinct, immaterial part of the pe…Read more

    Husserl’s complex attitude toward religion and theology is shaped by his critique of the metaphysical search in the works of contemporary phenomenologists. He was particularly concerned with the religious conversion experiences and interest in theology exhibited by some of them. This chapter examines the relationship between phenomenology and religion, focusing on Hedwig Conrad-Martius (1888–1966) and Edith Stein (1891–1942), two figures from the Munich-Göttingen Circle who rejected Husserl’s tr…Read more

    Academic Biography
    In Ruth Edith Hagengruber (ed.), The History of Women Philosophers: Festschrift in Honour of Mary Ellen Waithe, Springer. pp. 23-24. 2026.
    My academic life began at age 12 when I asked my devoutly-Catholic father how we can be sure that an event that the Church calls a ‘miracle’ isn’t just something that science has not figured out how to explain. Furious at my apparent apostasy, he called me “a goddamned philosopher.” I thought that the word “philosopher” meant “prostitute” and, growing up in New York City, I knew that those were the ladies who wore too much makeup and approached men in Times Square. So, not only was I crushed by …Read more

    If I Were King! Morals and Physics in Emilie Du Ch'telet’s Subtle Thoughts on Liberty
    In Jacqueline Broad & Karen Detlefsen (eds.), Women and Liberty, 1600-1800: Philosophical Essays, Oxford University Press. pp. 195-205. 2017.
    This chapter argues that Emilie Du Châtelet’s practical moral philosophy and her theoretical physics are intimately connected into a systematic whole. Both the moral philosophy and the physics exhibit the same method, which relies, for example, on the principle of contradiction. Du Châtelet uses this method to argue against the injustice of women’s reduced educational opportunity and thus reduced freedom, as well as identifying the source of women’s social ostracism. Moreover, this chapter also …Read more

    In times of current crisis, the voices of women are needed more than ever. The accumulation of war and environmental catastrophes teaches us that exploitation of people and nature through violent appropriation and enrichment for the sake of short-term self-interest exacts its price. This book presents contributions on the currently most relevant and most urgent issues: reshaping the economy, environmental problems, technology and the re-reading of history from the non-western and western traditi…Read more

    Du Châtelet's philosophical analysis of time as presented in her Institutions physiques (1742) challenges prevailing Newtonian and Wolffian theories, asserting that time is not an external, absolute entity nor solely based on a relativistic and mathematical perspective. It is presented to be a construct of the human mind, emerging through the interplay of unity and difference. Du Châtelet also introduces the concept of “ideal time,” a uniform abstraction that enables the measurement of successio…Read more
