In all cases, the problem concerns the proper meaning of subjunctive and counterfactual conditionals. For present purposes, a conditional sentence is one composed of at least two clauses, the central connective of which is, or is understood to be, "if... then." A subjunctive conditional is a conditional sentence in which the clause following the "if," the antecedent, may be true or false, but in which the truth or falsity of the entire sentence does not depend upon the truth or falsity (...) of its two clauses, the antecedent and consequent. A contrary-to-fact conditional, or counterfactual sentence, is a subjunctive conditional sentence which implicitly asserts that the antecedent is false. An example of the subjunctive conditional is.

Communication is defined as an interaction between at least two living agents which share a repertoire of signs. These are combined according to syntactic, semantic and context-dependent, pragmatic rules in order to coordinate behavior. This volume deals with the important roles of soil bacteria in parasitic and symbiotic interactions with viruses, plants, animals and fungi. Starting with a general overview of the key levels of communication between bacteria, further reviews examine the various aspects of intracellular as well as intercellular biocommunication (...) between soil microorganisms. This includes the various levels of biocommunication between phages and bacteria, between soil algae and bacteria, and between bacteria, fungi and plants in the rhizosphere, the role of plasmids and transposons, horizontal gene transfer, quorum sensing and quorum quenching, bacterial-host cohabitation, phage-mediated genetic exchange and soil viral ecology.

Catharine Macaulay's first political pamphlet, “Loose remarks on certain positions to be found in Mr. Hobbes's philosophical rudiments of government and society with a short sketch for a democratical form of government in a letter to Signor Paoli,” published in London in 1769, has received no significant scholarly attention in over two hundred years. It is of primary interest because of the light it sheds on Macaulay's critique of patriarchal politics, which helps to establish a new line of thinking about (...) the historian as an early feminist writer. It appears she was working from an unauthorized edition of the Thomas Hobbes'sDe Cive entitledPhilosophicall Rudiments of Government and Society, printed by a royalist bookseller in London 1651. Some errors in this translation may explain Macaulay's skewed understanding of Hobbess argument in support of the premises of monarchy. Her intriguing analysis of paternal authority in “Loose Remarks” anticipates recent feminist explorations of Hobbesian political thought. (shrink)

The present debate in legal theory is dominated by an unfruitful schism. On the one hand, analytical theories are concerned with the positivity of law, running the risk of missing the law's relation to society. On the other hand, sociological approaches analyze all sorts of social interactions of law, but have developed no conceptual tools to do justice to the autonomy of law. The theory of autopoiesis offers law a chance of getting round the falsely posed alternative between an autonomous (...) rule system or a socially conditioned decision-making process. It is a theory of law that sees the law's autonomy in the self-reproduction of a communication network and understands its relation to society as interference with other autonomous communication networks. Building on the ideas of Humberto Maturana, Heinz von Foerster and Niklas Luhmann, Gunther Teubner uses the concepts of self-organization and autopoiesis to develop a concept of law as a hypercyclically closed social system. This book will stand as a landmark in legal theory and become a standard point of departure in the sociology of law. (shrink)

The paper is concerned with Quine's substitutional account of logical truth. The critique of Quine's definition tends to focus on miscellaneous odds and ends, such as problems with identity. However, in an appendix to his influential article On Second Order Logic, George Boolos offered an ingenious argument that seems to diminish Quine's account of logical truth on a deeper level. In the article he shows that Quine's substitutional account of logical truth cannot be generalized properly to the general concept of (...) logical consequence. The purpose of this paper is threefold: first, to introduce the reader to the metamathematics of Quine's substitutional definition of logical truth; second, to make Boolos' result accessible to a broader audience by giving a detailed and self-contained presentation of his proof; and, finally, to discuss some of the possible implications and how a defender of the Quinean concepts might react to the challenge posed by Boolos' result.

Christianity changed the world for the better through the development of education, charity organisations, art, music, law and medical care among others. However, not all changes initiated by Christianity were positive. The Christian religion was also responsible for division, death, destruction and war. Focusing on the positive changes, nearly 500 years after the reformation though, it seems as if Christianity has lost its renewing and transformative powers. It seems as if society, politics and the economy are pressurising Christianity to conform (...) to the world and not the other way round. Therefore, the research focuses on the question whether Christians can bring about positive change and transformation to the current problems in society. What can Christians do to provide a religious response to current persistent societal problems? Change agents – people who drive positive change – are capable and competent, make use of networks, are visible and contactable and are often also outsiders in the communities they serve. Examples of the work done by change agents – Christians within their local communities – through small-scale community projects are showcased here to suggest possible ways forward for dealing with persistent problems from a Christian point of view.

The aim of this article is to contribute to a better understanding of Frege’s views on semantics and metatheory by looking at his take on several themes in nineteenth century geometry that were significant for the development of modern model-theoretic semantics. I will focus on three issues in which a central semantic idea, the idea of reinterpreting non-logical terms, gradually came to play a substantial role: the introduction of elements at infinity in projective geometry; the study of transfer principles, especially (...) the principle of duality; and the use of counterexamples in independence arguments. Based on a discussion of these issues and how nineteenth century geometers reflected about them, I will then look into Frege’s take on these matters. I conclude with a discussion of Frege’s views and what they entail for the debate about his stance towards semantics and metatheory more generally. (shrink)

In the twenty-second series of The Logic of Sense, Gilles Deleuze references a remarkable essay by Günther (Stern) Anders. Anders’ essay, translated here as ‘The Pathology of Freedom’, addresses the sickness and health of our negotiation with the negative anthropological condition of ‘not being cut out for the world’.

When two or more people coordinate their actions in space and time to produce a joint outcome, they perform a joint action. The perceptual, cognitive, and motor processes that enable individuals to coordinate their actions with others have been receiving increasing attention during the last decade, complementing earlier work on shared intentionality and discourse. This chapter reviews current theoretical concepts and empirical findings in order to provide a structured overview of the state of the art in joint action research. We (...) distinguish between planned and emergent coordination. In planned coordination, agents' behavior is driven by representations that specify the desired outcomes of joint action and the agent's own part in achieving these outcomes. In emergent coordination, coordinated behavior occurs due to perception action couplings that make multiple individuals act in similar ways, independently of joint plans. We review evidence for the two types of coordination and discuss potential synergies between them. (shrink)

The year 2017 is the year in which the Reformation, started by Martin Luther, is celebrating its 500th birthday. This depicts a milestone in the life of the Church of the Reformation and also in the life of Christians worldwide. This is a good time to ponder on the epistemological question of the validity and necessity of the Reformation. If this question is answered in a positive way, then it could bring us to the realisation that the time is ripe (...) for an African Reformation. This article will argue that this is indeed the case. A reformation, transformation and change is needed for the African Christian context. However, the question could well be asked: Who will be the 'second Luther?'. (shrink)

The knowledge driven, network society that is founded upon technology, demands from students to become independent, confident and motivated life-long, self-directed learners that can transfer their knowledge, skills and values. In order to deliver this type of graduates from a diverse and unequal student pool, effective education must be provided. Educators are encouraged to focus education on student-centeredness and to use technology effectively. Alternative assessment methods that are technology driven could enable both educators and students to become more effective in (...) this environment. This article advocates the use of alternative assessment methods by using technology driven assessment tools for possible replacement of traditional, paper based and ‘one size fits all’ assessment methods within theology. The SECTIONS framework was used to evaluate ten alternative assessment tools that are in accord with the development within society. (shrink)

Society is transforming from the industrial era to an information based, network society. Thereis widespread consensus that due to this revolution in society, education needs to make aparadigm shift in order to stay relevant to the changing needs of society. Although thisparadigm shift is promoted widely in academic literature, it seems as if in practice there arestumbling blocks preventing higher education to make positive strides into a new directionwithin the South African context. This research highlights some of the hurdles that (...) OpenDistance Learning higher education in South Africa is experiencing and also suggests apossible way forward to overcome these obstacles through the implementation of selfdeterminedlearning. In order for heutagogy to be implemented successfully,student support is of the upmost importance both in the curriculum design and the actualteaching and presenting of courses. (shrink)

This article applies change agency to the institutions of higher education in South Africa – referring here to all the post-school institutions and educators in general and more specifically focused on the unique opportunities and responsibilities towards change agency in theological training. The focus is on the characteristics of a change agent, which could be an individual or a group. Seemingly, change is not going to be initiated in a ‘top-down’ approach; therefore, this article suggests a ‘bottom-up’ approach, starting with (...) a change agent (an individual or a group) to become enthusiastic and active to bring about change. The method of constructivism is used, complemented by a general literature review of the past 70 years, filled with definitions of change agents and change agency. After the discussion of a few models, the researcher ventures to propose a way in which change agency can find a foothold among theological educators in higher education institutions in South Africa.

The article investigates one of the key contributions to modern structural mathematics, namely Hilbert’sFoundations of Geometry and its mathematical roots in nineteenth-century projective geometry. A central innovation of Hilbert’s book was to provide semantically minded independence proofs for various fragments of Euclidean geometry, thereby contributing to the development of the model-theoretic point of view in logical theory. Though it is generally acknowledged that the development of model theory is intimately bound up with innovations in 19th century geometry, so far, little (...) has been said about how exactly model-theoretic concepts grew out of methodological investigations within projective geometry. This article is supposed to fill this lacuna and investigates this geometrical prehistory of modern model theory, eventually leading up to Hilbert’sFoundations. (shrink)

Recent work by philosophers of mind and psychology on nonconceptual content.

From the 15th century onwards, most of the countries in Africa have been colonised by theEuropean world powers, Great Britain, France, Portugal, Germany, Spain, Italy and Belgium.South Africa was officially colonised in 1652. Apart from the European colonisation beingexecuted from the south of the continent, South Africa also experienced a migration andinvasion of people groups from the north. The indigenous people groups, inhabiting thecountry long before these two groups arrived there, will be discussed as background to the restof the article. (...) A few factors that made the colonisation of South Africa unique within theAfrican context will be discussed. (shrink)
