“…Extended work by others points at the relevance of discourse in the building of a perspective (Ayers 2005, Burke 1968, 1973cited in Herndl and Brown 1996, Teymur 1982, Herndl and Brown 1996, Myerson and Rydin 1996, Darier 1999, Harré et al 1999, Brulle 1996, Podeschi 2002, Kaldis 2003, Williams et al 2005. Many authors have reflected on environmental discourse (e.g., Teymur 1982, Ehrlich and Ehrlich 1996, Herndl and Brown 1996, Myerson and Rydin 1996, Darier 1999, Harré Environmental Values 16.3 et al1999, Brulle 1996, Podeschi 2002, Kaldis 2003). Among them, Kaldis (2003) points at a ʻcrisis of discoursesʼ, for which disciplinary concept schemes exert hegemonic control over the signification and values of environmental issues; language that serves other spheres of thought (e.g., scientism, managerial-utilitarian) restricts the way practitioners view and understand environmental issues.…”
