Conceptual engineers aim to revise rather than describe our concepts. But what are concepts? And how does one engineer them? Answering these questions is of central importance for implementing and theorizing about conceptual engineering. This paper discusses and criticizes two influential views of this issue: semanticism, according to which conceptual engineers aim to change linguistic meanings, and psychologism, according to which conceptual engineers aim to change psychological structures. I argue that neither of these accounts can give us the full story. (...) Instead, I propose and defend the Dual Content View of Conceptual Engineering. On this view, conceptual engineering targets concepts, where concepts are understood as having two kinds of contents: referential content and cognitive content. I show that this view is independently plausible and that it gives us a comprehensive account of conceptual engineering that helps to make progress on some of the most difficult problems surrounding conceptual engineering.

Conceptual engineering is the design, implementation, and evaluation of concepts. Conceptual engineering includes or should include de novo conceptual engineering (designing a new concept) as well as conceptual re-engineering (fixing an old concept). It should also include heteronymous (different-word) as well as homonymous (same-word) conceptual engineering. I discuss the importance and the difficulty of these sorts of conceptual engineering in philosophy and elsewhere.

Conceptual engineering means to provide a method to assess and improve our concepts working as cognitive devices. But conceptual engineering still lacks an account of what concepts are (as cognitive devices) and of what engineering is (in the case of cognition). And without such prior understanding of its subject matter, or so it is claimed here, conceptual engineering is bound to remain useless, merely operating as a piecemeal approach, with no overall grip on its target domain. The purpose of this (...) programmatic paper is to overcome this knowledge gap by providing some guidelines for developing the theories of concepts and of cognition that will ground the systematic unified framework needed to effectively implement conceptual engineering as a widely applicable method for the cognitive optimization of our conceptual devices.

In this paper, we discuss the following four alternative ways of understanding the outcomes of resurrection biology. Implications of each of the ways are discussed with respect to concepts of species and extinction. Replication: animals created by resurrection biology do not belong to the original species but are copies of it. The view is compatible with finality of extinction as well as with certain biological and ecological species concepts. Re-creation: animals created are members of the original species but, despite their (...) existence, the species remains extinct. The view is incompatible with all species concepts presented. Non-extinction: animals produced belong to the original species which actually never went extinct. The view may be consistent with phenetic and phylogenetic species concepts as well as with finality of extinction. According to literal resurrection, resurrection biology is successful in reversing extinction through the creation of new members of species that once went extinct. This view presupposes non-finality of extinction and it is compatible with phenetic species concepts. It is notable that no species or extinction concept is consistent with all possible views of resurrection biology nor is any view of resurrection biology consistent with all species or extinction concepts. Thus, one’s views regarding species and extinction determine which views one can adopt regarding resurrection biology and vice versa. (shrink)

Because of accelerating technological progress, humankind may be rapidly approaching a critical phase in its career. In addition to well-known threats such as nuclear holocaust, the propects of radically transforming technologies like nanotech systems and machine intelligence present us with unprecedented opportunities and risks. Our future, and whether we will have a future at all, may well be determined by how we deal with these challenges. In the case of radically transforming technologies, a better understanding of the transition dynamics from (...) a human to a "posthuman" society is needed. Of particular importance is to know where the pitfalls are: the ways in which things could go terminally wrong. While we have had long exposure to various personal, local, and endurable global hazards, this paper analyzes a recently emerging category: that of existential risks. These are threats that could case our extinction or destroy the potential of Earth - originating intelligent life. Some of these threats are relatively well known while others, including some of the gravest, have gone almost unrecognized. Existential risks have a cluster of features that make ordinary risk management ineffective. A final section of this paper discusses several ethical and policy implications. A clearer understanding of the threat picture will enable us to formulate better strategies. (shrink)

I begin by briefly tracing the history of the split between environmental ethics and animal liberation, go on to sketch a theory of value that I think is implicit in animal liberation, and explain how this theory is consistent with strong environmental commitments. I conclude with some observations about problems that remain.

In ethics, aesthetics and increasingly in epistemology, a distinction is drawn between thick and thin evaluative concepts. A common characterisation of the distinction is that thin concepts have only evaluative content, whereas thick concepts combine evaluative and descriptive content. Because of this combination, it is again commonly thought that thick concepts have various distinctive powers including the power to undermine the distinction between fact and value. This paper discusses the accuracy of this view of the thick concepts debate, as well (...) as assessing the prospects for a thick concepts argument against the fact value distinction, while introducing the three main philosophical positions on the nature of thick concepts.

Environmental philosophers often conflate the concepts of intrinsic value and moral standing. As a result, individualists needlessly deny intrinsic value to species, while holists falsely attribute moral standing to species. Conceived either as classes or as historical individuals, at least some species possess intrinsic value. Nevertheless, even if a species has interests or a good of its own, it cannot have moral standing because species lack sentience. Although there is a basis for duties toward some species (in terms of their (...) intrinsic value), it is not the one that the holists claim. (shrink)

[Sally Haslanger] In debates over the existence and nature of social kinds such as 'race' and 'gender', philosophers often rely heavily on our intuitions about the nature of the kind. Following this strategy, philosophers often reject social constructionist analyses, suggesting that they change rather than capture the meaning of the kind terms. However, given that social constructionists are often trying to debunk our ordinary (and ideology-ridden?) understandings of social kinds, it is not surprising that their analyses are counterintuitive. This article (...) argues that externalist insights from the critique of the analytic/synthetic distinction can be extended to justify social constructionist analyses. /// [Jennifer Saul] Sally Haslanger's 'What Good Are Our Intuitions? Philosophical Analysis and Social Kinds' is, among other things, a part of the theoretical underpinning for analyses of race and gender concepts that she discusses far more fully elsewhere. My reply focuses on these analyses of race and gender concepts, exploring the ways in which the theoretical work done in this paper and others can or cannot be used to defend these analyses against certain objections. I argue that the problems faced by Haslanger's analyses are in some ways less serious, and in some ways more serious, than they may at first appear. Along the way, I suggest that ordinary speakers may not in fact have race and gender concepts and I explore the ramifications of this claim. (shrink)

The phenomenon of species extinction raises more and more concern among ecologists facing the actual crisis of biodiversity. Scientific investigations of the causes and effects of extinction must be completed by a philosophical analysis of the concept of extinction that aims to clarify the meanings of the term ‘extinction’ and to analyse modalities, criteria and degrees of extinction. We will focus our attention on the apparent paradox of the possible ‘resurrection’ of species in the near future with the help of (...) genetic biotechnology and cloning techniques. The ontological background of the extinction concept is analysed in relation to the idea of species as classes. We will also show that there is no simple analogy between death and species extinction, and develop a conceptualist and dualistic system of supra-individual entities , supported by an instrumentalist approach to genetic manipulations which transform species into interactive kinds, which can go extinct and be recreated.

An environmental ethic holds that some entities in nature or in natural states of affairs are intrinsically valuable. I argue that proposals for an environmental ethic either fail to satisfy requirements which any ethical system must satisty to be an ethic or they fail to give us reason to suppose that the values they promote are intrinsic values. If my arguments are correct, then environmental ethics is not properly ethics at all.

Many theorists hold that there is, among value concepts, a fundamental distinction between thin ones and thick ones. Among thin ones are concepts like good and right. Among concepts that have been regarded as thick are discretion, caution, enterprise, industry, assiduity, frugality, economy, good sense, prudence, discernment, treachery, promise, brutality, courage, coward, lie, gratitude, lewd, perverted, rude, glorious, graceful, exploited, and, of course, many others. Roughly speaking, thick concepts are value concepts with significant descriptive content. I will discuss a number (...) of problems having to do with how best to understand the notion of a thick concept. Thick concepts have been widely discussed in the .. (shrink)

I defend a view of the species category, pluralistic realism, which is designed to do justice to the insights of many different groups of systematists. After arguing that species are sets and not individuals, I proceed to outline briefly some defects of the biological species concept. I draw the general moral that similar shortcomings arise for other popular views of the nature of species. These shortcomings arise because the legitimate interests of biology are diverse, and these diverse interests are reflected (...) in different legitimate approaches to the classification of organisms. In the final section, I show briefly how the pluralistic approach can help to illuminate some areas of biological and philosophical dispute. (shrink)

In this paper we apply social epistemology to mathematical proofs and their role in mathematical knowledge. The most famous modern collaborative mathematical proof effort is the Classification of Finite Simple Groups. The history and sociology of this proof have been well-documented by Alma Steingart (2012), who highlights a number of surprising and unusual features of this collaborative endeavour that set it apart from smaller-scale pieces of mathematics. These features raise a number of interesting philosophical issues, but have received very little (...) attention. In this paper, we will consider the philosophical tensions that Steingart uncovers, and use them to argue that the best account of the epistemic status of the Classification Theorem will be essentially and ineliminably social. This forms part of the broader argument that in order to understand mathematical proofs, we must appreciate their social aspects. (shrink)

Conceptual engineering is commonly characterized as the method for assessing and improving our representational devices. Little has been said, however, on how best to construe these representational devices—in other words, on what conceptual engineering should be all about. This paper tackles this problem with a basic strategy: First, by presenting a taxonomy of the different possible subject matters for conceptual engineering; then, by comparatively assessing them and selecting the most conducive one with a view to making conceptual engineering an actionable (...) method, that is, a method that can be applied effectively and consistently to specific case studies. The outcome is that conceptual engineering should be all about concepts on pain of pragmatic inconsistencies otherwise. (shrink)

ABSTRACTSeveral philosophers have inquired into the metaphysical limits of conceptual engineering: ‘Can we engineer? And if so, to what extent?’. This paper is not concerned with answering these questions. It does concern itself, however, with the limits of conceptual engineering, albeit in a largely unexplored sense: it cares about the normative, rather than about the metaphysical limits thereof. I first defend an optimistic claim: I argue that the ameliorative project has, so far, been too modest; there is little value theoretic (...) reason to restrict the project to remedying deficient representational devices, rather than go on a more ambitious quest: conceptual improvement. That being said, I also identify a limitation to the optimistic claim: I show that the ‘should’ in ameliorative projects suffers from a ‘wrong-kind-of-reasons’ problem. Last but not least, I sketch a proposal of normative constraining meant to address both the above results. The proposal gives primacy to epistemic constraints: accordingly, a concept should be ameliorated only insofar as this does not translate into epistemic loss. (shrink)

Many explanations in science make use of mathematics. But are there cases where the mathematical component of a scientific explanation is explanatory in its own right? This issue of mathematical explanations in science has been for the most part neglected. I argue that there are genuine mathematical explanations in science, and present in some detail an example of such an explanation, taken from evolutionary biology, involving periodical cicadas. I also indicate how the answer to my title question impacts on broader (...) issues in the philosophy of mathematics; in particular it may help platonists respond to a recent challenge by Joseph Melia concerning the force of the Indispensability Argument.

The precautionary principle has been widely discussed in the academic, legal, and policy arenas. This paper argues, however, that there is no single precautionary principle and we should stop referring to ?the? precautionary principle. Instead, we should talk about ?precaution? and ?precautionary approaches? more generally and identify and defend distinct precautionary principles of limited scope. Drawing on the vast literature on ?the? precautionary principle, this paper further argues that the challenges of decision making under conditions of uncertainty necessitate taking a (...) precautionary approach to decision making that will enable us to understand what particular precautionary principles require of us on a case-by-case basis.
