Subject: Intersubjectivity and Community in Logical and Mathematical Objectivity

Supervisor: Dr. Michael Roubach

Abstract: My dissertation aims to discuss different models of intersubjectivity and community, with a focus on their relations to logical and mathematical objectivity. It takes on the form of a comparative study of the structure and function of intersubjectivity and community in the philosophies of Edmund Husserl, Martin Heidegger, and Hans Georg Gadamer, mainly during the 1930s, with special attention to the way these notions relate to the concepts of mathematical and logical objectivity. Despite this historical backdrop, the motivation of the study is chiefly systematic; it aims to discuss, from a phenomenological perspective, the essential relation of different models of intersubjectivity and community to logical and mathematical objectivity.

The inquiry into the relation of intersubjectivity and community to mathematics and logic is twofold. First, I investigate the role which intersubjectivity and community play in the process of constituting logical and mathematical objectivity. A key step in gaining insight about this issue consists in defining the precise role which language plays in the constitution of logical and mathematical meaning, within a general framework of collective experience. Second, I also assess the extent to which some models of intersubjectivity and community themselves have a mathematical character. In this respect, this study attempts to show how a basic conception of mathematical objectivity is an integral part of the essential structure of transcendental intersubjectivity and primordial community.

Bio: I'm a PhD candidate in the department of Philosophy at the Hebrew University. My research focuses on Phenomenology in the 20th century, with an emphasis on the works of Edmund Husserl, Martin Heidegger, and Hans-Georg Gadamer. I hold a B.A in Philosophy and Art History (summa cum laude) and an M.A in Philosophy (summa cum laude) from Ben Gurion University of the Negev. My M.A thesis dealt with the question of the unity of the soul in Plato's "Timaeus" and "Philebus". In addition, I am interested in political philosophy, philosophy of science, and the relations between philosophy and literature. I like long backpacking trips, coffee, music, art, running, and homemade beer.
