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)

ABSTRACT It is obvious that Arne Naess had his most important philosophical experience, and quite possibly made his most significant achievement, in confrontation with the variety of philosophical scepticism known as Pyrrhonism. Naess maintained, however, that he did not defend scepticism as a philosophical position, and he was concerned to distinguish Pyrrhonism from the inverse form of dogmatism often associated with the term ?scepticism?. Naess was primarily preoccupied with the practical implications of this radical form of scepticism, in which he (...) thought peace of mind and serious inquisitiveness could be combined. In this article, I introduce some central aspects of Naess's Pyrrhonian scepticism, to illustrate how his philosophy may contribute to a relevant form of anti-dogmatism. (shrink)

Many of Tarski’s better known papers are either about or include lengthy discussions of how to properly define various concepts: truth, logical consequence, semantic concepts, or definability. In general, these papers identify two primary conditions for successful definitions: formal correctness and material adequacy. Material adequacy requires that the concept expressed by the formal definition capture the intuitive content of truth. Our primary interest in this paper is to better understand Tarski’s thinking about material adequacy, and whether components of his view (...) developed over time. More precisely, we are concerned with how Tarski’s understanding of the content of the common-sense, every-day usage of truth may have developed over time. We distinguish this concern from the character of the extensional criterion of adequacy Tarski proposes: that a materially adequate definition must entail all instances of Convention T. We will develop our reading of Tarski as follows: first, we will review the “Polemical Remarks,” focusing primarily on §§14 and 17, and Tarski’s references to Naess’ empirical research. Next, we will provide a summary and discussion of Naess’ work, especially his findings with respect to Tarski’s definition of truth and his research that suggests there is no single common or everyday concept of truth. Third, we will consider several possible objections to our interpretation of the Tarski–Naess dialectic. We will conclude that Tarski’s conception of material adequacy developed over time, potentially because of what he had learned through his interactions with Naess. (shrink)

Socratic irony can be understood independently of the immortal heroics of Plato’s Socrates. We need a systematic account and criticism of it both as a debate-winning strategy of argumentation and teaching method. The Speaker introduces an issue pretending to be at a lower intellectual level than her co-debaters, or Participants. An Audience looks over and evaluates the results. How is it possible that the Speaker like Socrates is, consistently, in the winning position? The situation is ironic because the Participants fight (...) from a losing position but realize it too late. Socratic irony compares with divine irony: divine irony is a subtype of Socratic irony since you lose when you challenge gods. Socratic irony is also, prima facie, a subtype of dramatic irony when the Audience knows more than the Participants on the stage. We must distinguish between the ideal and realistic elements of Socratic Irony. The very idea of Socratic irony looks idealized, or it is an ideal case, which explains the Speaker’s consistently winning position. In real life, the debate must be rigged, or the Dutch Book argument applies to the Participants, if the Speaker is so successful. (shrink)
