In commemoration of Husserl’s many years of teaching and research in Göttingen, the Göttingen Academy of Science staged an international symposium in Husserl’s jubilee year 2009. The results are presented in this edited volume. The contributions are arranged into three thematic groups: (1) Husserl’s philosophy of subjectivity, (2) Husserl’s theory of the intentional object and his definition of the relationship between truth and evidence, (3) Husserl’s philosophy of mathematics and logic.
