Aribiah Attoe took issue with the materialist and the non-materialist African conceptions of death by arguing that the reality of death puts pressure on the human conception of life’s meaning. He admits the reality of an afterlife experience through a causal principle that sees events in the world as the product of interactions between predetermined past events. It is an afterlife where a decomposing body continues interacting with other things in the world, not an afterlife involving consciousness. While conscious meaning-making (...) ends in the death of the body in Attoe’s materialist view, thereby affirming the conclusion that human existence is meaningless and the universe is purposeless, the conviction about life’s meaninglessness is also reinforced by the possibility of a second death, that is, the death of the transcendent consciousness in the traditional African view. In this article, I will mount two objections to Attoe’s submission. First, I argue that Attoe’s refutation of life’s meaning may be faulted by a world view devoid of the ideas of the afterlife and immortality. Life’s meaninglessness for him should have been limited to the facts of human existence in the world, not the human inability to continue meaning after death. Second, Attoe’s conception of death as finality questions his principle of causality that suggests the reality of an endless afterlife. Attoe’s overarching submission on life’s meaninglessness gives the impression that theories of life’s meaning must be anchored on the thought of an afterlife and immortality. (shrink)

Limited communitarianism is presented as an alternative to classical communitarianism in African philosophy. Bernard Matolino, the proponent of this view, argues that personhood can be attained with the constitutive features of the self leading the process, as against the historical, classical communitarian view that prioritises the sociality of the self. He posits that it is a personhood conceived through such view as limited communitarianism that can guarantee individual rights and prioritises the claims of the individual in African philosophy. Matolino’s claim (...) is grounded on the view that Afro-communitarianism, as presented in the classical account such as the radical and moderate communitarianism of Menkiti and Gyekye, respectively, emphasises community essence in African philosophy and hinders the expression of rights. The claim of the classical view informs the nudge to question the relevance and compatibility of Afro- communitarianism with the complex, multicultural modern African societies. As a result, limited communitarianism rejects the mechanism of Afrocommunitarianism – essentialism. While limited communitarianism appears a rejection of what is known as Afro- communitarianism, which has earned it noncommunitarian labels such as being liberal and individualist, I argue that it is simply a well- argued form of moderate communitarianism that avoids the conundrum of community.

In a joint article1 with Wenceslaus Kwindingwi, Bernard Matolino declared an end to ubuntu. The declaration, they argue, is a result of the failure of ubuntu in practice and theory in modern African societies. This declaration triggered strong reactions, and an analysis of these responses suggests the need for continuous interrogations of African ideals and beliefs and their relevance to modern African thought. In this article, I argue that Kwindingwi and Matolino’s argument is in line with Matolino’s broader scepticism about (...) Afro-communitarianism in general. In other works, he insists that attempts to theoretically and practically ground postcolonial African philosophy in ideas of Afro-communitarianism exaggerate its functionality. I aim to show that Matolino’s Socratic process and the outcomes, as demonstrated in the “The end of ubuntu”, aim to produce quality understanding and reasoned defence of the traditional ideas aimed to guide modern African thought. The rejectionist approach should be seen as a nudge to make the advocacy for African ideals and beliefs, such as ubuntu, match up with the knowledge of them and how they operate in reality. (shrink)

This paper proposes a Multi-Agent based Particle Swarm Optimization (PSO) Framework for the Traveling salesman problem (MAPSOFT). The framework is a deployment of the recently proposed intelligent multi-agent based PSO model by the authors. MAPSOFT is made up of groups of agents that interact with one another in a coordinated search effort within their environment and the solution space. A discrete version of the original multi-agent model is presented and applied to the Travelling Salesman Problem. Based on the simulation results (...) obtained, it was observed that agents retrospectively decide on their next moves based on consistent better fitness values obtained from present and prospective neighborhoods, and by reflecting back to previous behaviors and sticking to historically better results. These overall attributes help enhance the conventional PSO by providing more intelligence and autonomy within the swarm and thus contributed to the emergence of good results for the studied problem.

This paper is about the good side of modal logic, the bad side of modal logic, and how hybrid logic takes the good and fixes the bad.In essence, modal logic is a simple formalism for working with relational structures . But modal logic has no mechanism for referring to or reasoning about the individual nodes in such structures, and this lessens its effectiveness as a representation formalism. In their simplest form, hybrid logics are upgraded modal logics in which reference to (...) individual nodes is possible.But hybrid logic is a rather unusual modal upgrade. It pushes one simple idea as far as it will go: represent all information as formulas. This turns out to be the key needed to draw together a surprisingly diverse range of work . Moreover, it displays a number of knowledge representation issues in a new light, notably the importance of sorting. (shrink)

In the last thirty years, the problem of presupposition projection has been taken to provide a decisive argument for a dynamic approach to meaning, one in which expressions are not evaluated with respect to the ‘global’ context of utterance, but rather with respect to a ‘local context’ obtained by updating the global one with expressions that occur earlier in the sentence. The computation of local contexts is taken by dynamic analyses to follow from a generalization of the notion of belief (...) update. I argue that the dynamic approach is faced with a dilemma: in its pragmatic incarnation (Stalnaker), it is explanatory but not general; in its semantic incarnation (Karttunen and Heim), it is general but not explanatory. I suggest that the dilemma stems for a faulty understanding of ‘local contexts’, and I offer a new reconstruction of this notion which eschews belief update but offers a general and fully precise solution to the projection problem.

This chapter investigates the problem of knowledge production on economic poverty in Africa as, largely, an instance of epistemic injustice. It applies Karl Popper’s critical rationalism to the issue of knowledge production on poverty. Methodologies of researches on poverty in Africa subtly promotes intended epistemic injustices against the subjects as the poor are underrepresented in knowledge about them; the experiences of the poor are often ignored, and their epistemic capacity for unearthing the push and pull factors of poverty are greeted (...) with much inferiority, skepticism and contempt. In severing the intersection between researching and reporting poverty in Africa and epistemic injustice, this chapter argues that Popper’s critical rationalism is philosophically indispensable. Popper’s scientific and political thoughts are potent theoretical interventions in addressing the epistemic, methodological, social, moral and political problems of poverty in Africa. The elements of scientific method inquiry, rationality, piecemeal social engineering, liberalism and intellectual openness explicit in Popper’s philosophy are explored, applied and found relevant to promoting poverty research ideals and policy development in Africa and beyond. The chapter concludes on the importance of Popper’s works, which span beyond his time and space, to knowledge about Africa. (shrink)

The aim of this study was to examine developmental differences in autobiographical memory using a novel test that assesses its semantic and episodic subcomponents. Forty-two children aged 7–13 years were asked to recall semantic information and episodic events from three different time periods. For the recalls of all events, sense of remembering or sense of just knowing was measured via the Remember/Know paradigm. Age-related differences were observed for episodic autobiographical memory whereas semantic autobiographical memory was characterized by a relative developmental (...) invariance. The increase with age was also found in the number of “Remember” responses and their justification in terms of the actual contextual information retrieved—factual, spatial, and, more especially, temporal details. These findings highlight developmental differences between the episodic and semantic subcomponents of autobiographical memory and support the view that mental ‘time travel’ through subjective time, which allows one to re-experience the past through self-awareness, is the last feature of autobiographical memory to become fully operational.

We live in a world of rapidly advancing, revolutionary technologies that are not just reshaping our world and wars, but also creating a host of ethical questions that must be dealt with. But in trying to answer them, we must also explore why exactly is it so hard to have effective discussions about ethics, technology, and war in the first place? This article delves into the all-too-rarely discussed underlying issues that challenge the field of ethics when it comes to talking (...) about war, weapons, and moral conduct. These issues include the difficulty of communicating across fields; the complexity of real world dilemmas versus the seminar room and laboratory; the magnified role that money and funding sources play in shaping not just who gets to talk, but what they research; cross-cultural differences; the growing role of geographic and temporal distance issues; suspicion of the actual value of law and ethics in a harsh realm like war; and a growing suspicion of science itself. If we hope better to address our growing ethical concerns, we must face up to these underlying issues as well. (shrink)

Purpose: A study was made of attitudes of clinical geneticists regarding the age at which minors should be allowed to undergo a carrier test and the reasons they provide to explain their answer. Methods: European clinical institutions where genetic counselling is offered to patients were contacted. 177 (63%) of the 287 eligible respondents answered a questionnaire. Results: Clinical geneticists were significantly more in favour of providing a carrier test to a younger person if the request was made together with the (...) parents than if the adolescent requested the test personally. Although a large fraction of respondents (16%–30%) were “neither unwilling nor willing” to provide a carrier test to a 16-year-old adolescent who requested the test personally, for most disorders slightly more clinical geneticists were “very willing” or “willing”. Conclusion: Age is not the only decisive element when considering the participation of adolescents in decisions affecting their health. The clinical geneticists referred to cognitive, emotional and sexual maturity and the support of parents as crucial elements in their comments regarding when to tell children about their genetic risk or to allow adolescents to request a carrier test.

In his book, The Principles of Mathematics , the young Bertrand Russell abandoned the common-sense notion that the whole must be greater than its part, and argued that wholes and their parts can be similar, e.g. where both are infinite series, the one being a sub-series of the other. He also rejected the popular view that the idea of an infinite number is self-contradictory, and that an infinite set or collection is an impossibility. In this paper, I intend to re-examine (...) Russell's wisdom in doing both these things, and see if it might not have made more sense, and caused his enterprise fewer problems, if he had simply stuck to our commonplace ideas. To this end, I shall also be considering his treatment of certain paradoxes that he claims can only be resolved by the abandonment of the above notions, as well as certain others which his theories appear to have generated.

Ideal interpretation is understanding a text in the best possible way. It is usually used when the text has a canonical status, such as the Bible or the U.S. Constitution. We argue that Zhu Xi’s view about interpreting the Four Books and Ronald Dworkin’s view about constitutional interpretation are examples of ideal interpretation and that their basic principles are similar. Each holds, roughly, that their target text contains moral truth; that the author’s mind requires the mediation of learning; that the (...) purpose of interpretation is not only to lead the reader to the moral truth but to become a better person; that all propositions are about the same moral truth or about political justice; that the interpretation ultimately must come from oneself, purged of prejudices; and that the only correct interpretation is one that captures the original meaning.

In medieval writers an important distinction was drawn between two applications of the term ‘logica’: there was logica utens, the practice of thinking logically about this or that subject-matter, and there was logica docens, the construction of logical theory. Of course the English word ‘logic’ and its derivative ‘logical’ have a corresponding twofold meaning, and we ignore the distinction at the risk of serious confusion. ‘Logical thought’ may mean thinking that is being commended as orderly, consistent, and consequent, whatever its (...) subject-matter; or it may mean the thinking of logicians about logic, which alas has not always exhibited these virtues. Similarly for ‘teaching logic’: there is trying to get people, by precept and example, to be orderly, consistent, and consequent in their thinking, and there is the endeavour to train logicians for the next generation. In any respectable philosophy department there will be someone teaching logic in the first sense; in my own university there are very many first-year undergraduates who do a course called Reason and Argument with this aim. But we hold that the teacher of such logica utens must himself have a sufficient skill in logica docens if he is to do his job properly; and we undertake the further task of training people in logical theory so that some of them, who have sufficient native ability and motivation, may take up the torch from their teachers.

The accepted narrative treats John Stuart Mill's Kinds as the historical prototype for our natural kinds, but Mill actually employs two separate notions: Kinds and natural groups. Considering these, along with the accounts of Mill's 19th-century interlocutors, forces us to recognize two distinct questions. First, what marks a natural kind as worthy of inclusion in taxonomy? Second, what exists in the world that makes a category meet that criterion? Mill's two notions offer separate answers to the two questions: natural groups (...) for taxonomy, and Kinds for ontology. This distinction is ignored in many contemporary debates about natural kinds and is obscured by the standard narrative which treats our natural kinds just as a development of Mill's Kinds. (shrink)

When David Lewis ( 1986 ) told us that possible worlds were a ‘paradise for philosophers’, he neglected to add that they are a minefield for decision theorists. Possibilities — be they nomological, metaphysical, or epistemic possibilities — have little to do with subjective probabilities, and it is these latter that matter most to decision theory. Bernard Katz and Doris Olin ( 2007 ) have tried to solve the two-envelope problem by appealing to possible worlds and counterfactual conditionals. In this (...) article, I explain why any such attempt is misguided, and why we, qua decision theorists, must focus on the probable rather than the possible. (shrink)
