This paper expresses certain qualms about causal theories of time, Such as have been put forward by h. Mehlberg and adolf gruenbaum. These qualms arise from doubts about the clarity of the notion of causality. It is suggested that a metalinguistic concept of causality cannot occur within the object language of physics, And that any non-Metalinguistic concept of causality leads to more difficulties than do the concepts of physical geometry which a causal theory of time is supposed to elucidate.

Advances in the understanding of genetics have led to the belief that it may become possible to use genetic engineering to manipulate the DNA of humans at the embryonic stage to produce certain desirable traits. Although this currently cannot be done on a large scale, many people nevertheless object in principle to such practices. Most often, they argue that genetic enhancements would harm the children who were engineered, cause societal harms, or that the risks of perfecting the procedures are too (...) high to proceed. However, many of these same people do not have serious objections to what is called ‘genetic planning’ procedures (such as the selection of sperm donors with desirable traits) that essentially have the same ends. The author calls the view that genetic engineering enhancements are impermissible while genetic planning enhancements are permissible the ‘popular view’, and argues that the typical reasons people give for the popular view fail to distinguish the two practices. This paper provides a principle that can salvage the popular view, which stresses that offspring from genetic engineering practices have grounds for complaint because they are identical to the pre-enhanced embryo, whereas offspring who are the result of genetic planning have no such grounds.

La situación laboral de los países desarrollados impone a la filosofía la tarea de pensar el trabajo en cuanto que los cambios producidos pueden afectar - y de hecho afectan- a la concepción de la persona, de la sociedad y del mundo actual. En este artículo, después de cuestionar que estemos asistiendo al final del trabajo a causa de la revolución tecnológica, analizaremos dos propuestas de reducción y reorganización del tiempo de trabajo, y otras dos que hacen referencia a un (...) cambio de paradigma: una rompe la actual barrera entre trabajo asalariado y trabajo no monetarizado, y la otra defiende el subsidio universal garantizado.

It is easy to have about the temporal present, the time that is now, thoughts that seem both true and impossible. E.g., ‘Now is the time that matters'. We may reflect that this is not just true but that ‘it is always like that', that is: now is always the time that matters. Yet here we seem to be generalizing the ascription to the temporal present of a property that claims uniqueness, viz., being the time that matters. The present paper (...) explores, in the case of the temporal present, the meaning and implications of this kind of impossible generalisation. (shrink)
