I Can we make promises to ourselves? This is a question that has not received much consideration in the large body of philosophical work on promising. And in what commentary there is, the answer is uniformly negative. I think this negativity is a mistake, and that the conventional view that we can't make reflexive promises is wrong. I also think that this has some important implications for promissory theory in general. In what follows, I will attempt to argue for the (...) first of these two claims, and to briefly outline my reasons for the second. (shrink)

Philosophers often understand environmental sustainability as a duty of distributive justice between the generations of the earth. Since every generation is equally entitled to the bounty of the natural environment (the thinking goes) every generation should have a fair share of that bounty. But since generations precede each other in time, it is the duty of earlier generations to ensure that later generations receive their fair share. Acting sustainably is the way of meeting this duty, since sustainable practices are those (...) that (ideally) preserve the environment for the future. But what is a 'fair' share of something as complex, varied and dynamic as 'the environment'? How are we to value nature for the purposes of measuring 'shares' of it? I think the answer to these questions lies in the difference between sharing something by parts, like a pie, and sharing something by turns, like a bicycle. The generations share the earth by turns, not by parts, and so questions about fairness of shares are questions about turns, not parts. We need to ask what constitutes a 'fair turn' with the earth, and for that question we don't necessarily need to be able to commensurate the various parts of nature, just as we don't need to know the relative value of the parts of a bicycle to say what constitutes a fair turn with it.

In 1985, wildlife biologist Michael Soulé wrote a manifesto for the new field of Conservation Biology. In it he offered ‘Diversity of organisms is good’ and ‘Ecological complexity is...

There is a widely held view that the rules forbidding the use of performance enhancing drugs (PEDs) are justified on grounds that utilizing these drugs constitutes cheating . In this chapter we engage with this assumption. Relying on an interpretative approach borrowed from Ronald Dworkin, we offer a novel analysis of cheating, one that makes it out to be a matter of inhibiting the attainment of certain sorts of achievements. These achievements are the important goods at the centre of sport, (...) the telos of sport. We then argue that a given enhancement should be regarded as cheating only when it inhibits or prevents competitors from realizing these important goods. (shrink)
