Failure is a central notion both in ethics of engineering and in engineering practice. Engineers devote considerable resources to assure their products will not fail and considerable progress has been made in the development of tools and methods for understanding and avoiding failure. Engineering ethics, on the other hand, is concerned with the moral and social aspects related to the causes and consequences of technological failures. But what is meant by failure, and what does it mean that a failure has (...) occurred? The subject of this paper is how engineers use and define this notion. Although a traditional definition of failure can be identified that is shared by a large part of the engineering community, the literature shows that engineers are willing to consider as failures also events and circumstance that are at odds with this traditional definition. These cases violate one or more of three assumptions made by the traditional approach to failure. An alternative approach, inspired by the notion of product life cycle, is proposed which dispenses with these assumptions. Besides being able to address the traditional cases of failure, it can deal successfully with the problematic cases. The adoption of a life cycle perspective allows the introduction of a clearer notion of failure and allows a classification of failure phenomena that takes into account the roles of stakeholders involved in the various stages of a product life cycle.

This paper defends the view that standards, which are typically social in nature, play a role in determining whether a subject has knowledge. While the argument focuses on standards that pertain to reasoning, I also consider whether there are similar standards for memory and perception.Ultimately, I argue that the standards are context sensitive and, as such, we must view attributions of knowledge as indexical. I exploit similarities between this view and a version of the relevant alternatives reply to skepticism in (...) order to defend this reply against the objection that it is ad hoc. (shrink)

Contextualists such as Cohen and DeRose claim that the truth conditions of knowledge attributions vary contextually, in particular that the strength of epistemic position required for one to be truly ascribed knowledge depends on features of the attributor's context. Contextualists support their view by appeal to our intuitions about when it's correct (or incorrect) to ascribe knowledge. Someone might argue that some of these intuitions merely reflect when it is conversationally appropriate to ascribe knowledge, not when knowledge is truly ascribed, (...) and so try to accommodate these intuitions even on an invariantist view. DeRose (Blackwell Guide to Epistemology, 1998; Philosophical Review, 2002) argues that any such 'warranted assertibility manoeuvre', or 'WAM', against contextualism is unlikely to succeed. Here, I argue that his objections to a WAM against contextualism are not persuasive and offer a pragmatic account of the data about ascriptions of knowledge. (shrink)

What are the strengths and weaknesses of contemporary philosophy of technology, and how may the field be developed and improved in the future? That is the question I will address in this paper. I will argue that in the past twenty-five years, philosophy of technology has entered a new era. This era has arrived with new and distinct issues and approaches that differ from those that came before it. Many of the new developments have been for the good. Yet, I (...) will also argue, there are still large areas in the field that are currently underdeveloped or have been stagnant. I will identify these areas and suggest ways of moving forward in them.

This article presents an overview of discussions in the philosophy of technology on epistemological relations between science and technology, illustrating that often several mutually entangled issues are at stake. The focus is on conceptual and ideological issues concerning the relationship between scientific and technological knowledge. It argues that a widely accepted hierarchy between science and technology, which echoes classic conceptions of epistêmê and technê, engendered the need of emancipating technology from science, thus shifting focus to epistemic aspects of engineering design (...) and design methodology at the cost of in-depth philosophical analysis of the role of scientific research in the engineering sciences. Consequently, the majority of current literature on this topic in the philosophy of technology presents technology as almost completely divided from and independent of science, thereby losing sight of the epistemic relations between contemporary scientific practices and technology.

Unlike basic sciences, scientific research in advanced technologies aims to explain, predict, and (mathematically) describe not phenomena in nature, but phenomena in technological artefacts, thereby producing knowledge that is utilized in technological design. This article first explains why the covering-law view of applying science is inadequate for characterizing this research practice. Instead, the covering-law approach and causal explanation are integrated in this practice. Ludwig Prandtl's approach to concrete fluid flows is used as an example of scientific research in the engineering (...) sciences. A methodology of distinguishing between regions in space and/or phases in time that show distinct physical behaviours is specific to this research practice. Accordingly, two types of models specific to the engineering sciences are introduced. The diagrammatic model represents the causal explanation of physical behaviour in distinct spatial regions or time phases; the nomo-mathematical model represents the phenomenon in terms of a set of mathematically formulated laws.

This paper is concerned with scientific reasoning in the engineering sciences. Engineering sciences aim at explaining, predicting and describing physical phenomena occurring in technological devices. The focus of this paper is on mathematical description. These mathematical descriptions are important to computer-aided engineering or design programs (CAE and CAD). The first part of this paper explains why a traditional view, according to which scientific laws explain and predict phenomena and processes, is problematic. In the second part, the reasons of these methodological (...) difficulties are analyzed. Ludwig Prandtl’s method of integrating a theoretical and empirical approach is used as an example of good scientific practice. Based on this analysis, a distinction is made between different types of laws that play a role in constructing mathematical descriptions of phenomena. A central assumption in understanding research methodology is that, instead of scientific laws, knowledge of capacities and mechanisms are primary in the engineering sciences. Another important aspect in methodology of the engineering sciences is that in explaining a phenomenon or process spatial regions are distinguished in which distinct physical behaviour occur. The mechanisms in distinct spatial regions are represented in a so-called diagrammatic model. The construction of a mathematical description of the phenomenon or process is based on this diagrammatic model. (shrink)

Abstract One of the most popular objections against epistemic contextualism is the so-called ?warranted assertability? objection. The objection is based on the possibility of a ?warranted assertability manoeuvre?, also known as a WAM. I argue here that WAMs are of very limited scope and importance. An important class of cases cannot be dealt with by WAMs. No analogue of WAMs is available for these cases. One should thus not take WAMs too seriously in the debate about epistemic contextualism.

Any artefact – a hammer, a telescope, an artificial hip – may malfunction. Conceptually speaking, artefacts have an inherent normative aspect. I argue that the normativity of artefacts should be understood as part of reality, and not just “in our concepts.” I first set out Deflationary Views of artefacts, according to which there are no artefactual properties, just artefactual concepts. According to my contrasting view – the Constitution View – there are artefactual properties that things in the world really have. (...) For example, there is a property of being a telephone per se; we apply our concept telephone to things that have that property. Things that have the property of being a telephone are constituted by, but not identical to, aggregates of particles. To be an artefact, an object must have an intended function, among other things. Telephones – in virtue of being the kind of objects that they are – are always subject to malfunction. And malfunctions, when they occur, are just as much part of the world as telephones are. The example of artefacts shows that what is in the world – what really exists – need not be “mind-independent” nor independent of our concepts. (shrink)

This volume features 16 essays on the philosophy of technology that discuss its identity, its position in philosophy in general, and the role of empirical studies in philosophical analyses of engineering ethics and engineering practices. This volume is published about fifteen years after Peter Kroes and Anthonie Meijers published a collection of papers under the title The empirical turn in the philosophy of technology, in which they called for a reorientation toward the practice of engineering, and sketched the likely benefits (...) for philosophy of technology of pursuing its major questions in an empirically informed way. The essays in this volume fall apart in two different kinds. One kind follows up on The empirical turn discussion about what the philosophy of technology is all about. It continues the search for the identity of the philosophy of technology by asking what comes after the empirical turn. The other kind of essays follows the call for an empirical turn in the philosophy of technology by showing how it may be realized with regard to particular topics. Together these essays offer the reader an overview of the state of the art of an empirically informed philosophy of technology and of various views on the empirical turn as a stepping stone into the future of the philosophy of technology.

Dennett has argued that when people interpret artifacts and other designed objects ( such as biological items ) they rely on optimality considerations , rather than on designer's intentions. On his view , we infer an item's function by finding out what it is best at; and such functional attribution is more reliable than when we depend on the intention it was developed with. This paper examines research in cognitive psychology and archaeology , and argues that Dennett's account is implausible. (...) We conclude that , quite in contrast to Dennett , intentional considerations play a crucial role in artifact hermeneutics , and even stronger , are necessary for the sake of simplicity and precision. Finally , we question Dennett's contention that the interpretation of artifacts is the same project as the interpretation of any other designed entity. (shrink)

This paper critically examines the forays into metaphysics of The Dual Nature of Technical Artifacts Program (henceforth, DNP). I argue that the work of DNP is a valuable contribution to the epistemology of certain aspects of artifact design and use, but that it fails to advance a persuasive metaphysic. A central problem is that DNP approaches ontology from within a functionalist framework that is mainly concerned with ascriptions and justified beliefs. Thus, the materiality of artifacts emerges only as the external (...) conditions of realizability of function ascription. The work of DNP has a strong programmatic aspect and much of its foray into metaphysics is tentative, so the intent of my argument is partly synthetic: to sum up these issues as they are presented in the literature and highlight some recognized problems. But I also go beyond that, suggesting that these problems are foundational, arising from the very way in which DNP poses the question of artifact metaphysics. Although it sets out to incorporate objective aspects of technology, DNP places a strong focus on the intentional side of the purported matter-mind duality, bracketing off materiality in an irretrievable manner. Thus, some of the advantages of dualism are lost. I claim that DNP is dualistic, not merely based on “duality”, but that its version of dualism does not appropriately account for the material “nature” of artifacts. The paper ends by suggesting some correctives and alternatives to Dual Nature theory. (shrink)

It is often noted that institutional objects and artifacts depend on human beliefs and intentions and so fail to meet the realist paradigm of mind-independent objects. In this paper I draw out exactly in what ways the thesis of mind-independence fails, and show that it has some surprising consequences. For the specific forms of mind-dependence involved entail that we have certain forms of epistemic privilege with regard to our own institutional and artifactual kinds, protecting us from certain possibilities of ignorance (...) and error; they also demonstrate that not all cases of reference to these kinds can proceed along a causal model. As a result, realist views in ontology, epistemology, and semantics that were developed with natural scientific kinds in mind cannot fully apply to the everyday world. In closing I consider some wider consequences of these results for social science and philosophy. (shrink)

Contextualists offer "high-low standards" practical cases to show that a variety of knowledge standards are in play in different ordinary contexts. These cases show nothing of the sort, I maintain. However Keith DeRose gives an ingenious argument that standards for knowledge do go up in high-stakes cases. According to the knowledge account of assertion (Kn), only knowledge warrants assertion. Kn combined with the context sensitivity of assertability yields contextualism about knowledge. But is Kn correct? I offer a rival account of (...) warranted assertion and argue that it beats Kn as a response to the "knowledge" version of Moore's Paradox. (shrink)

Jason Stanley's "Knowledge and Practical Interests" is a brilliant book, combining insights about knowledge with a careful examination of how recent views in epistemology fit with the best of recent linguistic semantics. Although I am largely convinced by Stanley's objections to epistemic contextualism, I will try in what follows to formulate a version that might have some prospect of escaping his powerful critique.

The classic version of the relevant alternatives theory (RAT) identifies knowledge with the elimination of relevant alternatives (Dretske 1981, Stine 1976, Lewis 1996, inter alia). I argue that the RAT is trapped by the problem of the missed clue, in which the subject sees but does not appreciate decisive information.

ABSTRACT Before “applied science” and “technology” became keywords, the concept of art was central to discourse about material culture and its connections to natural knowledge. By the late nineteenth century, a new discourse of applied science had replaced the older discourse of art. This older discourse of art, especially as presented in Enlightenment encyclopedias, addressed the relationship between art and science in depth. But during the nineteenth century the concept of fine art gradually displaced the broader meanings of “art,” thus (...) undermining the utility of the term for discourse on the relationship between knowledge and practice. This narrowed meaning of “art” obscured key aspects of the industrial world. In effect, middle-class agents of industrialism, including “men of science,” used the rhetoric of “applied science” and, later, “technology” to cement the exclusion of artisanal knowledge from the discourse of industrial modernity.

A wide variety of skills, abilities and knowledge are used in technological activities such as engineering design. Together, they enable problem solving and artefact creation. Gilbert Ryle’s division of knowledge into knowing how and knowing that is often referred to when discussing this technological knowledge. Ryle’s view has been questioned and criticised by those who claim that there is only one type, for instance, Jason Stanley and Timothy Williamson who claim that knowing how is really a form of knowing that (...) and Stephen Hetherington who claims that knowing that is knowing how. Neither Ryle himself nor any of his critics have discussed technological knowledge. Exposing both Ryle’s and his critics’ ideas to technological knowledge show that there are strong reasons to keep the knowing how–knowing that dichotomy in technological contexts. The main reasons are that they are justified in different ways, that Stanley’s and Williamson’s ideas have great difficulties to account for learning of technological knowing how through training, and that knowing that is susceptible to Gettier problems, which technological knowing how is not.

Why do our intuitive knowledge ascriptions shift when a subject's practical interests are mentioned? Many efforts to answer this question have focused on empirical linguistic evidence for context sensitivity in knowledge claims, but the empirical psychology of belief formation and attribution also merits attention. The present paper examines a major psychological factor (called ?need-for-closure?) relevant to ascriptions involving practical interests. Need-for-closure plays an important role in determining whether one has a settled belief; it also influences the accuracy of one's cognition. (...) Given these effects, it is a mistake to assume that high- and low-stakes subjects provided with the same initial evidence are perceived to enjoy belief formation that is the same as far as truth-conducive factors are concerned. This mistaken assumption has underpinned contextualist and interest-relative invariantist treatments of cases in which contrasting knowledge ascriptions are elicited by descriptions of subjects with the same initial information and different stakes. The paper argues that intellectualist invariantism can easily accommodate such cases. (shrink)

Summary The rise to dominance of school culture in engineering education took place much later in England and the U.S.A. than in France or Germany. Why? This comparative essay argues that explanations are to be sought within the context of bureaucracy rather than in that of industrialization. The academic training of state engineers set a powerful role model in Continental Europe but was absent in Anglo-America. Consequently, the academic training of engineers for the private sector of the economy started earlier (...) in Continental Europe, and the professional strategies of the engineers included emulating the public service. During the late nineteenth century a general belief in education as a key to international competition joined forces with a thorough transformation of the economy in providing new job markets for engineers graduating from colleges and universities.

“Pure science” and “applied science” have peculiar histories in the United States. Both terms were in use in the early part of the nineteenth century, but it was only in the last decades that they took on new meanings and became commonplace in the discourse of American scientists. The rise in their currency reflected an acute concern about the corruption of character and the real possibilities of commercializing scientific knowledge. “Pure” was the preference of scientists who wanted to emphasize their (...) nonpecuniary motives and their distance from the marketplace. “Applied” was the choice of scientists who accepted patents and profits as other possible returns on their research. In general, the frequent conjoining of “pure” and “applied” bespoke the inseparable relations of science and capitalism in the Gilded Age. (shrink)

DeRose appeals to ordinary English usage to support his contextualist semantics for "know"-attributions. A common objection holds that though the relevant assertions are both appropriate and seemingly true, their seeming truth arises merely from their appropriateness. This Warranted Assertability Maneuver (WAM) aims to provide a stand-alone objection by providing a reason not to take the ordinary language data at face-value. However, there is no plausible model or mechanism for the pragmatic phenomena WAMmers must postulate. Given what the WAM requires, it (...) is doubtful it could work out in detail. (shrink)

In recent years, the idea has been gaining ground that our traditional conceptions of knowledge and cognition are unduly limiting, in that they privilege what goes on inside the ‘skin and skull’ of an individual reasoner. Instead, it has been argued, knowledge and cognition need to be understood as embodied, situated, and extended. Whether these various interrelations and dependencies are ‘merely’ causal, or are in a more fundamental sense constitutive of knowledge and cognition, is as much a matter of controversy (...) as the degree to which they pose a challenge to ‘traditional’ conceptions of cognition, knowledge and the mind. In this paper we argue that when the idea of ‘extendedness’ is applied to a core concept in epistemology and the philosophy of science—namely, scientific evidence—things appear to be on a much surer footing. The evidential status of data gathered through extended processes—including its utility as justification or warrant—do not seem to be weakened by virtue of being extended, but instead are often strengthened because of it. Indeed, it is often precisely by virtue of this extendedness that scientific evidence grounds knowledge claims, which individuals may subsequently ascribe to themselves. The functional equivalence between machine-based gathering, filtering, and processing of data and human interpretation and assessment is the crucial factor in deciding whether evidence has been gathered, rather than the distinction between intra- and extracranial processes or individual and social processes. To prioritize biological processes here, and to assert the superiority of human cognitive capacities seems both arbitrary and unwarranted with respect to gathering evidence, and ultimately would lead to an unattractive skepticism about many of the methods used in science to gather evidence. In other words, conceiving of scientific evidence as ‘impersonal’ not only better captures the character of evidence-gathering in practice, but also makes sense of a large amount of evidence-gathering that ‘personal’ accounts fail to either acknowledge or accurately describe. Whilst we suggest it is likely that all internally-distributed evidence-gathering processes are merely contingently internal processes, a significant number of externally-distributed evidence-gathering processes are necessarily externally-distributed. Some evidence can only be gathered by extended epistemic agents. (shrink)

We examine to what extent an adequate ontology of technical artefacts can be based on existing general accounts of the relation between higher-order objects and their material basis. We consider two of these accounts: supervenience and constitution. We take as our starting point the thesis that artefacts have a ‘dual nature’, that is, that they are both material bodies and functional objects. We present two criteria for an adequate ontology of artefacts, ‘Underdetermination’ and ‘Realizability Constraints’ , which address aspects of (...) the dual nature thesis. Assessing supervenience accounts, we find them either wanting with respect to these criteria or insufficiently informative. Next, we argue that a recent application of Lynne Rudder Baker’s constitution view to artefacts cannot meet our criteria, although the broader view leaves room for improvement. Based on our evaluation of the most promising candidates, we conclude that so far general metaphysical views fail to address the most salient features of artefacts. Although they can account for the fact that artefacts have a ‘dual nature’, they do not offer the conceptual resources needed to describe the relation between these natures; this relation raises a hard problem in metaphysics.Keywords: Metaphysics; Artefact; Supervenience; Constitution; Underdetermination.

I argue that technological functions warrant specific epistemological attention, which they have not received thus far. From a user’s perspective, knowledge about the possible functions of an artefact is not provided exclusively by beliefs about its physical characteristics; it is primarily provided by know-how related to its use. Analysing the latter shows that standards of practical and not just theoretical reasoning are involved. Moreover, knowledge of the function of artefacts is primarily based on testimony and a social division of labour (...) with respect to rational artefact use. Combining these two features, knowledge of functions can be shown to create a rich normative context, manifest in notions such as ‘improper’ use: designers inform users about how they ought to use artefacts. This normativity in knowledge of functions, which takes a different shape for possible and proper functions, is lacking in standard, descriptive knowledge.Keywords: Epistemology; Function; Knowing-how; Testimony; Artefact; Practical rationality.
