ABSTRACT
Two distinct but related issues are discussed in this chapter. The first is how our use of language is implicated in our understanding of both sustainable development and learning as ideas. The second is how language is further implicated in our choice of actions in relation to sustainable development and learning as practice. We shall argue that a degree of insight into these matters is indispensable for any degree of practical planning in relation to our topic if it is to be effective. This is so even if some of the concepts involved initially may seem, to some at least, rather slippery, somewhat arcane or intellectually quite narcissistic.
