Migration and Sustainability

In 'The Environmental Argument for Reducing Immigration Into the United States', Philip Cafaro and Winthrop Staples III argue that, given Americans' disproportionate "environmental footprint", environmentalists should want to halt population growth in the U.S., and hence to severely restrict immigration into the U.S.

Despite the authors' constant mentions of "population growth", migration of course doesn't (in itself) alter the global population. So what they're really objecting to is allowing poor people from dysfunctional countries the opportunity to increase their wealth (and hence consumption) through hard work in a place where their hard work will be better rewarded. Because material consumption is bad for the environment. So we should do what we can to keep people poor, including blocking their access to countries with better infrastructure, institutions, etc. After all, if they're stuck in a failed state, with no roads and barely enough reward from their work to put food on their family's plates, they'll use less gas! Yay! (Right?)

Parfit on Philosophical Waste

It seems strangely common for commentators to misrepresent Parfit as claiming that a mistaken philosophical project (e.g. exploring and defending a false theory) lacks all value. Eric Schliesser previously attributed to Parfit the view "that there is no philosophic value (pure waste) in failure." (Sadly, Eric refused to correct this misattribution even when prompted.) More recently, Philip Kitcher writes:

If Naturalism is true, then many of Parfit’s claims are indeed wrong and his perspective is indeed askew. Does it follow that his efforts (and consequently much of his life) have been wasted? I do not think so. Almost all those who have engaged in any form of inquiry have been wrong and misguided...
