Having its seeds in the 2nd International Lauener Symposium held in honour of Dagfinn Føllesdal, the present collection contains a rich, kaleidoscopic ensemble of previously unpublished contributions by leading authors, representing diverse approaches to a variety of philosophical themes on which Føllesdal has had a longstanding, formative impact. Føllesdal himself contributes an orientating essay – continuing to develop his pioneering theory of reference – as well as in-depth commentaries on each of the other authors’ elaborated papers plus candid answers in the added interview. The volume assembles a wealth of original articles containing in part direct discussions of Føllesdal’s work and covering a broad range of topics like subjectivity, intersubjectivity, objectivity, rationality, logics and mathematics, choice theory, values, modalities, intentionality, individuation, perception, communication, meaning, reference, the slingshot, one- and two-sorted semantics, evidence, neuropsychology, space and time, science and society, methodology, fallibilism, the relative a priori, justification, holism, the life-world, reflective equilibrium, empathy, and ethics. Moreover the book includes an incisive memoir of Føllesdal the philosopher as well as a spanning interview with him, which are both critically directing toward Føllesdal’s subtly differentiated understanding of the dynamic philosophical horizon he shares in.
