In the approximation that every inertial observer experiences a homogeneous, uniform flow of time and sees a space that is Euclidean, the arena of physics is Minkowskian and one speed is the same in all intertial frames. If a given intertial observer finds an infinitesimal source or particle traveling faster than this fundamental speed near a given event, the source must appear in some inertial frame spread over neighboring positions at a given time as a spacelike structure. If this structure (...) persists over a period of proper time, it can be interpreted as a wave group. If it is conserved, it can be interpreted as a line or tube of force. (shrink)

In Oneself as Another, Ricœur famously writes of the ethical intention as “aiming at the ‘good life’ with and for others, in just institutions.” This article explores the potential meaning of “just institutions,” a theme underdeveloped in Ricœur’s work. While many have argued that institutions necessarily reify and so cannot aim toward just ends, the article draws on Ricœur’s differentiation between objectification and reification to show why this need not be the case. While reification destroys human value and meaning because (...) it reduces human activity to a thing, objectification characterizes the positive externalization of ourselves in objects—in words, deeds, structures, and institutions. Institutions such as the law are structures that can positively objectify our just aspirations, even if we must continually guard against these structures’ reified reduction. Ricœur shows us how objectification, including objectification of values in institutions, can be something not only positive but necessary in order for values to flourish. (shrink)
