In your own words, describe what Thompson means by "functional integrity" and "resource sufficiency" -- the two paradigms he proposes for practically conceptualizing sustainability. Then, explain what Thompson means by "non-substantive sustainability," and how it falls within the dichotomy of empirical (practical) and normative (value based) considerations.
Finally, consider Thompson's conclusion as to the role of "non-substantive sustainability" within the functionality of sustainability as a movement. Do you agree with his conclusion? What is the role of philosophical arguments, such as those presented in this text, in our understanding of sustainability?
