Every single day, every newspaper in the world carries some further evidence as to how limited the Earth’s resources are. Every single day, therefore, we should grow more deeply convinced that the notion of abundance has become hopelessly irrelevant and can safely be shelved forever. Or so it seems. In the final section of this paper, I shall defend the opposite view: that growing awareness of the limits of our resources should make the notion of abundance, suitably defined, more and (...) not less relevant to our pursuits. Whether or not this defence turns out to be successful, I hope this paper will go some way towards clarifying this notoriously elusive notion, as well as its no less elusive and no less important antonym: scarcity.
