The paper addresses the following question: why do human beings, on Aristotle’s view, have an innate tendency to badness, that is, to developing desires that go beyond, and often against, their natural needs? Given Aristotle’s teleological assumptions (including the thesis that nature does nothing in vain), such tendency should not be present. I argue that the culprit is to be found in the workings of rationality. In particular, it is the presence of theoretical reason that necessitates the limitless nature of (...) human non-rational desires. (shrink)

Aristotle’s Meteorology 4.12 is puzzling, in part because the chapter appears to extend teleological explanation to include certain inorganic materials without natural biological functions, such as metals and stone. This paper examines two attempts to explain why such materials can have functions, and shows that they are problematic. As an alternative, I argue that raw inorganic materials—as well as separated parts of organisms—can have extrinsic functions. Extrinsic functions can explain why natural inorganic materials can be sorted into natural kinds, even (...) if their functions are ultimately related to their uses in the productive arts. (shrink)

In the shift from the balance of nature to the flux of nature paradigm, the concept of resilience has gained great traction in ecology. While it has been suggested that the concept of resilience does not imply a genuine departure from the balance of nature paradigm, I shall argue against this stance. To do so, I first show that the balance of nature paradigm and the related conception of a single-state equilibrium relies on what Eliot Sober has named the “Natural (...) State Model (NSM)”, suggesting that the NSM has instead been dismissed in the flux of nature paradigm. I then focus on resilience as the main explanatory concept of the flux paradigm. After distinguishing between two main different understandings of “resilience”, namely engineering resilience and ecological resilience, I argue that the former is close to the concept of balance or stability and still part of the NSM, while the latter is not. Finally, I claim that ecological resilience is inconsistent with the NSM, concluding that this concept–being incompatible with the NSM–is not part of the balance of nature paradigm but rather a genuinely new explanatory tool.
