In the late forties and in the fifties, what was then known as the Oslo School of Philosophy, that is, Arne Naess and his students, received some fame, or notoriety, for its empirical investigations of lay uses of various epistemological terms, such as 'true', 'certain', 'probable'. It is less known that Arne Naess, in 1953, opened up a series of investigations into conceptual frameworks, the comparability of conceptual frameworks, and the senses, if any, in which a conceptual framework can be (...) said to represent knowledge. In the course of these investigations Arne Naess, together with some of his students, developed views that are strikingly close to those of Ludwig Wittgenstein in ber Gewissheit. This paper examines some of those similarities and a few dissimilarities. (shrink)

A clarification of Naess's ?depth metaphor? is offered. The relationship between Naess's empirical semantics and communication theory and his deep ecology approach to ecophilosophy (DEA) is developed. Naess's efforts to highlight significant conflicts by eliminating misunderstandings and promoting deep problematizing are focused upon. These insights are used to develop the implications of the DEA for environmental policy. Naess's efforts to promote the integration of science, ethics, and politics are related to the National Environmental Policy Act (NEPA). The action?oriented aspect of (...) deep ecology, its focus upon redirecting environmental policy, is also highlighted. The discussion is framed by Brian Norton's contention, in Toward Unity Among Environmentalists, that Naess's deep/ shallow distinction is not consequential. In the final section some of the uniqueness of Naess's contribution is intimated, the ?sturdiness? of deep ecology's foundation is considered, and directions for future theoretical and practical contributions are suggested. As will be observed, Naess has many important insights to offer, but some vexing issues persist. (shrink)
