What is new here is the detailed discussion of several important results in the classical foundations of mathematics and of the relation of logic to mathematics. As regards logical questions, the central thesis of Wittgenstein's later philosophy is well known, both from the earlier posthumous volume and from the writings of his many disciples. In the Investigations the thesis is applied to the "logic of our expressions" in everyday contexts; here he discusses in the same spirit the more specialized language (...) used in talking about the foundations of mathematics.

Explores the extraordinary states of expanded consciousness that arise during comas, both positive and negative.

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of idealization because (...) they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

The themes of the book—the value of knowledge and epistemic appraisal broadly conceived—are introduced in this chapter. The Meno problem is explained and related to the swamping problem as discussed by Jonathan Kvanvig. The stance of virtue epistemologists is outlined. This is followed by a brief discussion of the role of truth in epistemic appraisal. The remainder of the introduction summarises the contributions to the book.

O texto investiga algumas dimensões do pensamento de Levinas em relação aos temas da linguagem, justiça, perdão e pluralidade, entre outros, a partir da leitura talmúdica “Envers Autrui”, estabelecendo relações com alguns aspectos da filosofia analítica e do pensamento do Kant e William Galston.

Although retroviral integration requires specific viral DNA sequences, factors which govern the choice of a chromosomal target site within an infected celi are less clear. For example, certain chromosomal regions may be inaccessible to the viral integration machinery, while others may favor integration. A recent paper by Withers‐Ward et al.(1) addresses this issue using a polymerase chain reaction‐based assay capable of identifying single integration events within a large population of infected cells. Their results show that integration can occur into many (...) different chromosomal regions, and that local DNA structure can influence the site of integration within a given region. (shrink)

Explores Russell's activities as a polemicist, agitator, educator, and popularizer and discusses the evolution of his moral philosophy and its application, including his final battle against American intervention in Vietnam.

Michael Tooley defends infanticide by analysing ‘A has a right to X’ as roughly synonymous with ‘If A desires X, then others are under a prima facie obligation to refrain from actions that would deprive him [or her] of it.’ An infant who cannot conceive of himself or herself as a continuing subject of experiences cannot desire to continue existing. Hence, on Tooley’s analysis, killing the infant is not impermissible, for it does not go against any of the infant’s desires. (...) However, Tooley’s argument in support of his analysis seems to justify, instead, a slightly more subtle analysis—namely, ‘A has a right to X’ is roughly extensionally equivalent with ‘Unless A expresses his or her desire that not‐X, then others are under a prima facie obligation to refrain from actions that would deprive him or her of X.’ But given this analysis, the infant’s purported lack of any capacity to conceive of himself or herself as a continuing subject of experiences implies that we cannot be released from any duty that we might have not to harm him or her. In short, Tooley’s argument in support of his analysis actually implies that infanticide may well be impermissible. (shrink)

In her dedicated promotion of feminism and pacifism, especially during the 1930s, Vera Brittain (1893–1970) was strongly influenced by Ber­trand Russell’s writings, especially Marriage and Morals (1929) and Which Way to Peace? (1936). Both were members of the Peace Pledge Union, and she continued as a sponsor after Russell abandoned his pac­ifism soon after the beginning of the Second World War. She admired his political and social activism in the aftermath of that war, endorsing it as much as her family (...) situation allowed; and, as chairman of the Peace News board, Brittain intervened in Russell’s support when a dispute broke out between him and the editor. Although their rela­tionship was personally limited, Russell’s influence on her opinions and actions was profound. (shrink)

Taking religious freedom as illustrative, this essay proposes a theory of the basic freedoms that pacifies the conflict among libertarian, egalitarian, and communitarian sects of liberalism. This theory follows John Rawls’s suggestion that constitutional courts are exemplars of public reason but rejects his partisan construal of public reason in terms that only an egalitarian liberal would recognize. If, as Rawls argues, liberal pluralism is reasonable and if constitutional courts are guardians of public reason, then an ideal constitutional court will guide (...) itself by the theory of the basic freedoms that reconciles liberal pluralism with the rule of public reason. Such a theory will integrate the plurality of liberal sects into an inclusive liberalism that preserves a distinctive role for each in defining and limiting constitutional rights, while refining them of the errors resulting from their hegemonic ambitions. Liberal pluralism is thus preserved, but liberal fragmentation is overcome. Public reason is sought not through an escape from pluralism but in a logical concord among the denominations of liberalism. The way for courts to execute this concord in constitutional cases is to follow the method of reasoning they have already largely adopted. That method is proportionality review. (shrink)

It is easy to read Hobbes's moral thinking as a deviant contribution to 'modern' natural law, especially if Leviathan (1651) is read through a lens provided by De Cive (1642). But The Elements of Law (1640) encourages the view that Hobbes's argument is 'physicalist', that is, that it requires no premises beyond those required by his physics of matter in motion. The Elements included a draft De Homine and its argument is intimately connected with De Cive's; it shows how such (...) concepts as 'reason', 'right', 'natural law' and 'obligation' can be understood in physicalist terms. But Hobbes's decision to print the latter work in isolation has led to serious misunderstandings. (shrink)
