In his “Space, supervenience and substantivalism”, Le Poidevin proposes a substantivalism in which space is discrete, implying that there are unmediated spatial relations between neighboring primitive points. This proposition is motivated by his concern that relationism suffers from an explanatory lacuna and that substantivalism gives rise to a vicious regress. Le Poidevin implicitly requires that the relationist be committed to the “only x and y ” principle regarding spatial relations. It is not obvious that the relationist is committed to this (...) principle in such a context. An additional motivation for Le Poidevin's argument, that space should be considered to be discrete, is that he believes that substantivalists are committed to a vicious regress. I show that the regress is in fact not of the vicious variety. These two main arguments show that Le Poidevin's suggestion that we drop the density postulate for space is unnecessary. (shrink)

Everettian Interpretations of Quantum Mechanics Between the 1920s and the 1950s, the mathematical results of quantum mechanics were interpreted according to what is often referred to as “the standard interpretation” or the “Copenhagen interpretation.” This interpretation is known as the “collapse interpretation" because it supposes that an observer external to a system causes the system, … Continue reading Everettian Interpretations of Quantum Mechanics →.

In this paper, we use qualitative and quantitative research, along with reference to current philosophical literature to consider the question of whether the sport of free-soloing is inherently immoral given the unavoidable extreme risk taken by the climber and imposed upon others not directly participating in the sport. The first thing we look at is what kind of values climbers see in free-soloing and show, through interviews we conducted with soloers and through a review of the literature on the philosophy (...) of extreme sports, that climbers derive what might be called ‘higher pleasures’ from free-soloing. We then argue that despite its inherent riskiness, free-soloers ought to be allowed the autonomy and freedom to choose to engage in the sport, provided they are doing so in a conscientious manner. To show that they are, we again appeal to interviews we conducted to demonstrate that soloers decide to attempt a free-solo in a thoughtful manner, as prescribed by philosophers who work on the morality...
