turned on its head. It is limitless growth on a finite planet that is unrealistic. After all, what could be more utopian, in the pejorative sense, than the neoclassical growth model which takes as 'given' certain non-physical parameters (e.g. market price, preferences, technology, wealth distribution, etc.) but on that basis purports to be independent of the biophysical laws of nature? Recognising the biophysical (and other) limits to growth may indeed require a radical new approach to how economies are structured, as I have argued it does; but this would be in recognition of certain realities, not in any attempt to transcend them. In a second sense, however, the charge of utopianism should be embraced, not as an indictment, but as a defence. 'Without the hypothesis that a different world is possible,' Genevieve Decrop has recently stated, 'there can be no politics, but only the administrative management of men [sic] and things' (as quoted in Latouche, 2009: 32). In this sense, the sufficiency economy is indeed a utopian vision, arising out of a defiant faith that a different world is possible. But as Serge Latouche (2009: 32) has aptly explained with respect to the degrowth movement, 'Far from representing a flight of fancy, it is an attempt to explore the objective possibility of its implementation.' With a nod to Latouche, the sufficiency economy described above should be understood in similar terms. Imagining the alternative is the first step toward its realisation. But there is a third sense in which the sufficiency
