Arne Næss

Næss averred that while western environmental groups of the early post–World War II period had raised public awareness of the environmental issues of the time, they had largely failed to have insight into and address what he argued were the underlying cultural and philosophical background to these problems. Næss believed that the environmental crisis of the twentieth century had arisen due to certain unspoken philosophical presuppositions and attitudes within modern western developed societies which remained unacknowledged. He thereby distinguished between what he called deep and shallow ecological thinking. In contrast to the prevailing utilitarian pragmatism of western businesses and governments, he advocated that a true understanding of nature would give rise to a point of view that appreciates the value of biological diversity, understanding that each living thing is dependent on the existence of other creatures in the complex web of interrelationships that is the natural world.

Næss was born in Slemdal, Oslo, Norway, the son of Christine (Dekke) and Ragnar Eide Næss. Ragnar was a successful banker, and Arne was the younger brother of shipowner Erling Dekke Næss. Næss had two children with his first wife Else and was the uncle of mountaineer and businessman Arne Næss Jr. (1937–2004). In 1939, Næss was the youngest person to be appointed full professor at the University of Oslo and the only professor of philosophy in the country at the time. He was a noted mountaineer, who in 1950 led the expedition that made the first ascent of Tirich Mir (7,708 metres or 25,289 feet) in Pakistan, depicted in the documentary film Tirich Mir til topps. The Tvergastein hut in the Hallingskarvet massif played an important role in the name of Næss's philosophy, "Ecosophy T", as "T" is said to represent his mountain hut Tvergastein. In 1958, he founded the interdisciplinary journal of philosophy Inquiry. In 1970, together with a large number of protesters, he chained himself to rocks in front of Mardalsfossen, a waterfall in a Norwegian fjord, and refused to descend until plans to build a dam were dropped. Though the demonstrators were carried away by police and the dam was eventually built, the demonstration launched a more activist phase of Norwegian environmentalism. When he was 61, while guest-lecturing at the University of Hong Kong, he met Kit-Fai Tsui, a philosophy student who was four decades younger than him, whom he married seventeen years later. In 1996, he won the Swedish Academy Nordic Prize, known as the "little Nobel". In 2005 he was decorated as a Commander with Star of the Royal Norwegian Order of St. Olav for socially useful work. Næss was a minor political candidate for the Norwegian Green Party in 2005. Næss died on 12 January 2009, at the age of 96.

Næss's book Communication and Argument (1966) included his recommendations for objective public debate. Næss argued for adhering to the following principles to make discussions as fruitful and pleasant as possible: "Avoid tendentious references to side issues"—distractions such as personal attacks, claims about opponents' motivation, or irrelevant explanations or arguments. "Avoid tendentious renderings of other people's views"—editing quotes or paraphrasing in a biased or misleading way (for example, quoting out of context). "Avoid tendentious ambiguity"—deliberately offering ambiguous statements instead of more precise ones (equivocation). "Avoid tendentious argument from alleged implication"—assigning views to opponents that they do not hold (straw men). "Avoid tendentious firsthand reports"—information that is untrue or incomplete, withholding relevant information (for example, lying by omission). "Avoid tendentious use of contexts"—presenting material with extra accessories of persuasion and suggestion such as visual or aural appeals to emotion of irony, sarcasm, insult, exaggeration, or subtle (or open) threat. For many years these points were part of a compulsory course in philosophy (examen philosophicum) taught in Norwegian universities. Argumentation theorist Erik Krabbe later said that Næss's principles for effective discussion were precursors of the rules for critical discussion in pragma-dialectics.

Ecosophy T, as distinct from deep ecology, was originally the name of Næss's personal philosophy. Others such as Warwick Fox have interpreted deep ecology as a commitment to ecosophy T, Næss's personal beliefs. The "T" referred to Tvergastein, a mountain hut where he wrote many of his books, and reflected Næss's view that everyone should develop his own philosophy. Næss's ecosophy can be summed up as self-realization. According to Næss, every being, whether human, animal or vegetable, has an equal right to live and to blossom. Næss states that through self-realization humans can become part of the ecosystems of Earth, in distinction to becoming only themselves. According to one writer, Næss defined the ethical consequences of self-realization as: If one does not know how the outcomes of one's actions will affect other beings, one should not act. In an article that summarized Næss's career, Nina Witoszek noted that he qualified his most radical propositions using the rhetorical term "in principle", and he pragmatically recognized that, in Witoszek's words, "concessions are unavoidable; dogmas are ductile; and practice diverges from principle".
