An award-winning theoretical physicist and best-selling author of A Universe from Nothing traces the dramatic discovery of the counterintuitive world of reality, explaining how readers can shift their perspectives to gain greater understandings of our individual roles in the universe.

The Century between the death of Copernicus and the birth of Newton witnessed a major reshaping of traditional ways of viewing the universe. The Ptolemaic system was challenged by Copernican heliocentrism, the Aristotelian world was assailed by Galilean physics and revived atomism, and theology was troubled by the progressive distancing of God from the daily operation of His creation. Besides earning this era the title of ‘the Scientific Revolution’, the intellectual ferment of these times offered many world systems as successors (...) to the throne of crumbling Aristotelianism.

In recent years, a particular doctrine about forms of life has come to be associated with Wittgenstein's name by followers and critics of his philosophy alike. It is not a doctrine which Wittgenstein espoused or even, given his understanding of philosophy, one which he could have accepted; nor is it worthy of acceptance on its own merits. I shall here outline the standard interpretation of Wittgenstein's remarks on forms of life, consider the textual basis for such a reading of Wittgenstein, (...) present a more consistent reading of the texts, place the problem of forms of life within a wider philosophical context, and show the ways in which it is indeed possible to say that a form of life is wrong. In the process, I shall note some important similarities between Wittgenstein's actual position, Quine's analysis of scientific knowledge, and Hans-Georg Gadamer's claims about the fusion of horizons.

Corpus linguistics is becoming a respected method of statutory and constitutional interpretation in the United States over the past decade, yet it has also generated a backlash from a group of scholars that engage in empirical work. This essay attempts to demonstrate both the contributions and the risks of using linguistic corpora as a primary tool in legal interpretation. Its legitimacy stems from the fact that courts routinely state that statutory terms, when not defined as a matter of law, are (...) to be given their ordinary meaning. Judges have responded to this challenge, with the assistance of the linguistics community, by using corpora to determine which meanings are ordinary. However, legal analysts have not determined exactly what makes one meaning ordinary and another not ordinary. This gap has led to a level of disagreement in the field. Moreover, while linguists who engage in corpus linguistic analysis typically emphasize the importance of context, the legal application is peculiarly context-free, in keeping with legal philosophies that eschew reliance on reference to a law’s purpose and the intent of the legislature that enacted it. This move adds a political dimension to corpus analysis as a means of legal interpretation. Yet, the article concludes that by relying on a blend of general and specialized corpora, the legal system can substantially reduce the problem of contextualization, as some linguists and practitioners have already recognized.

During development, large numbers of cells die by a process known as programmed cell death. This loss of cells plays a number of important roles, including the sculpting of the body form and the removal of vestigial tissues. Data obtained from a variety of organisms has suggested that a cell's ‘decision’ to die is a differentiative event, requiring the activation of specific sets of genes. Several putative ‘cell death’ genes have recently been cloned, and one has been identified as the (...) product of the polyubiquitin gene. Accumulation of ubiquitin has been observed not only during programmed cell death, but also in several neurodegenerative disorders, including Alzheimer's Disease. (shrink)

En 1705, Wilhem Homberg, le principal chimiste de l’Académie royale des sciences, proposa une nouvelle théorie chimique selon laquelle le Soufre principe des corps mixtes était identique à la lumière. Il affirma par la suite que cette lumière corporelle était la seule source d’activité et de changement dans les substances matérielles. Cet article montre comment la théorie de Homberg s’élabora progressivement pendant de nombreuses années sous l’influence de ses observations et des résultats de ses expériences de laboratoire, ce qui nous (...) fournit un exemple de la manière selon laquelle un chimiste du début du XVIIIe siècle a pu développer une théorie raffinée grâce à l’interaction de la réflexion et de la manipulation. L’influence probable de la théorie de Homberg sur les fameuses « questions chimiques » de Newton est également signalée ici pour la première fois. Enfin l’article avance que nous comprendrons plus précisément l’histoire de la chimie si nous reconnaissons le caractère spécifique de la chimie et sa relative autonomie, plutôt que si nous cherchons à lui imposer des développements faciles et convenus tirés d’autres champs du savoir comme la philosophie ou la physique.

Shepard proposes that the human mind relies on screw displacement because of its adaptive simplicity and uniqueness. I discuss this hypothesis by assessing screw displacement with respect to (1) other plausible spatial transformations, (2) a variety of criteria for adaptive efficiency and utility, and (3) a variety of psychological conditions in which observed responses discriminate amongst alternative spatial procedures.

The essay is an attempt to examine aspects of legal interpretation from an external, sociological point of view. “Interpretation”, in its normal juristic sense, is primarily a process in which decision‐makers with secondary legitimacy link their decisions to authority of primary legitimacy. The type of legitimacy which is dominant within the legal system greatly influences the style of interpretation ‐ in “closed” systems, where the stock of premises is fixed, “legalism” will abound. Legal interpretation is not concerned with what a (...) text really means, in any literal sense; and standards for judging legal interpretation are different from the standards of judging other forms of communication, for example, literature. Indeed, a judge can be considered great precisely because of his creative acts of misinterpretation. (shrink)

It is a tacit assumption among most contemporary American and British philosophers that the question of style in philosophy is, at most, an issue of peripheral importance. Although it is generally agreed that a well developed sense of style may make a philosopher’s work more accessible and thus be a factor in its acceptance by a wider audience, and although it seems self-evident to many that the apparent inaccessibility of much of continental philosophy is due in part to stylistic vagaries (...) to which it is particularly prone, few would accord to style an importance beyond this. Certainly style is not an integral part of a philosophical position. It is always possible in principle, so the dominant view today suggests, to separate the position being expressed from the style the author employs in expressing it. The position itself is equated with the body of propositions that the philosopher is asserting; the style in which these are expressed either has no bearing on the truth value of the propositions and is consequently irrelevant or else it can be incorporated into either the propositions themselves or the structure of the argument, in which case it is no longer primarily a stylistic consideration. In either case, a philosopher’s style is ultimately not integral to the position which he advances. (shrink)
