In this paper we present an action-theoretic account of artefact using and designing and describe our ICE-theory of function ascriptions to technical artefacts. By means of this account and theory we analyse the thesis of the dual nature of technical artefacts according to which descriptions of technical artefacts draw on structural and intentional conceptualisations. We show that the ascription of technical functions to technical artefacts can connect the intentional and structural parts of descriptions of (...) artefacts, but also separate these parts. Our conclusion is that the concept of technical functions forms a ‘conceptual drawbridge’ between the intentional and structural natures of technical artefacts.Keywords: Intentional and structural descriptions; Technical artefacts; Function theory; Action theory; Use; Design.

The paper argues that in order to understand the nature of technological knowledge (i.e., knowledge of technical artefacts as distinct from knowledge of natural objects) it is necessary to develop an epistemology of technical functions. This epistemology has to address the problem of the meaning of the notion of function. In the dominant interpretations, functions are considered to be dispositions, comparable to physical dispositions such as fragility and solubility. It is argued that this conception of functions is (...) principally flawed. With the help of Carnap’s analysis of dispositional terms it is shown that there is a fundamental difference between physical dispositional terms and functional dispositional terms. This difference concerns the issue of the normativity; with regard to functional dispositions, it makes sense to construct normative statements of a particular kind, with regard to physical dispositions it does not.

According to the dual nature thesis, technical artifacts have a dual nature: they are material objects that have a material base, but also functions that depend on their intentional history, in particular their intended and actual use. In an influential paper, Houkes and Meijers argue that the dual nature thesis does not square well with the seemingly plausible idea that the function of a technological artifact supervenes on its material base. They correctly point out that many versions of (...) the supervenience thesis are unable to account for the following two-way underdetermination condition: “an artefact type, as a functional type, is multiply realizable in material structures or systems, while a given material basis can realize a variety of functions” (Houkes and Meijers 2006, 120). In this paper, I articulate a supervenience thesis that is compatible with the two-way underdetermination condition. (shrink)

Current philosophical theorizing about technical functions is mainly focused on specifying conditions under which agents are justified in ascribing functions to technical artifacts. Yet, assessing the precise explanatory relevance of such function ascriptions is, by and large, a neglected topic in the philosophy of technical artifacts and technical functions. We assess the explanatory utility of ascriptions of technical functions in the following three explanation-seeking contexts: why was artifact x produced?, why does artifact x not (...) have the expected capacity to ϕ?, how does artifact x realize its capacity to ϕ? We argue that while function ascriptions serve a mere heuristic role in the first context, they have substantial explanatory leverage in the second and third context. In addition, we assess the relevance of function ascriptions in the context of engineering redesign. Here, function ascriptions also play a relevant role: they enable normative statements of the sort that component b functions better than component a. We unpack these claims by considering philosophical theories of technical functions, in particular the ICE theory, and engineering work on function ascription and explanation. We close the paper by relating our analysis to current debates on the explanatory power of mechanistic vis-à-vis functional explanations. (shrink)

The aim of this paper is to evaluate etiological accounts of functions for the domain of technical artefacts. Etiological theories ascribe functions to items on the basis of the causal histories of those items; they apply relatively straightforwardly to the biological domain, in which neo-Darwinian evolutionary theory provides a well-developed and generally accepted background for describing the causal histories of biological items. Yet there is no well-developed and generally accepted theory for describing the causal history of artefacts, so the (...) application of etiological theories to the technical domain is hardly straightforward. In this paper we consider the transposition of etiological theories in general from the biological to the technical domain. We argue that a number of etiological theories that appear defensible for biology become untenable for technology. We illustrate our argument by showing that the standard etiological accounts of Neander and Millikan, and some recent attempts to improve on them, provide examples of such untenable theories. 1 Introduction 2 Desiderata for theories of functions 3 Etiological theories in general 3.1 Common core and divergent aims 3.2 Reproduction versus non-reproduction etiological theories 3.3 Intentionalist versus non-intentionalist etiological theories 4 Problems for etiological theories in the technical domain 5 The failure of existing reproduction theories 6 The failure of existing non-reproduction theories 7 Improving reproduction by hybridisation 8 Conclusions.

Neuroscientists have long sought to study the dynamic activity of the human brain—what's happening in the brain, that is, while people are thinking, feeling, and acting. Ideally, an inside look at brain function would simultaneously and continuously measure the biochemical state of every cell in the central nervous system. While such a miraculous method is science fiction, a century of progress in neuroimaging technologies has made such simultaneous and continuous measurement a plausible fiction. Despite this progress, practitioners of modern (...) neuroimaging struggle with two kinds of limitations: those that attend the particular neuroimaging methods we have today and those that would limit any method of imaging neural activity, no matter how powerful.In this essay, I consider the liabilities and potential of techniques that measure human brain activity. I am concerned here only with methods that measure relevant physiologic states of the central nervous system and relate those measures to particular mental states. I will consider in particular the preeminent method of functional neuroimaging: BOLD fMRI. While there are several practical limits on the biological information that current technologies can measure, these limits—as important as they are—are minor in comparison to the fundamental logical restraints on the conclusions that can be drawn from brain imaging studies.

It is argued that we cannot understand the notion of proper functions of artefacts independently of social notions. Functions of artefacts are related to social facts via the use of artefacts. The arguments in this article can be used to improve existing function theories that look to the causal history of artefacts to determine the function. A view that takes the intentions of designers into account to determine the proper function is both natural and often correct, but (...) it is shown that there are exceptions to this. Taking a social constitutive element into account may amend these backwards looking theories. An improved theory may either have a disjunctive form—either the history or collective intentions determine the proper function—or, as is suggested in the article, be in the form of an encompassing account that views the designers’ intentions as social, in so far as they are accepted by the users. Designers have authority, which is a social fact. The views argued for here are applied to two existing theories of artefact functions, a causal historic approach and an action theoretic approach.Keywords: Function; Artefact; Evaluative judgement; Action; Collective intentionality.

In 2006, in a special issue of this journal, several authors explored what they called the dual nature of artefacts. The core idea is simple, but attractive: to make sense of an artefact, one needs to consider both its physical nature—its being a material object—and its intentional nature—its being an entity designed to further human ends and needs. The authors construe the intentional component quite narrowly, though: it just refers to the artefact’s function, its being a means to realize (...) a certain practical end. Although such strong focus on functions is quite natural , I argue in this paper that an artefact’s intentional nature is not exhausted by functional considerations. Many non-functional properties of artefacts—such as their marketability and ease of manufacture—testify to the intentions of their users/designers; and I show that if these sorts of considerations are included, one gets much more satisfactory explanations of artefacts, their design, and normativity.Keywords: Artefacts; Dual Nature program; Function; Intentionality; Normativity.

This article aims to introduce English-speaking readers to a still little-known tradition of French philosophy of technology: the “biological philosophy of technology.” As recognized by Georges Canguilhem, this philosophy was initiated by Henri Bergson, who conceived of technology as an extension of life, which in its evolution, creates natural tools (organs) and artificial ones (technical objects). The paleontologist André Leroi-Gourhan took up this thesis and put it to the test of archaeological data to demonstrate, on the one hand, the (...) biological basis of technical evolution and on the other hand, the importance of technics for human evolution. Finally, Gilbert Simondon extended Leroi-Gourhan’s scientific technology from the study of tools to that of machines, providing yet another fruitful example of the biological philosophy of technology.

In this paper, it is examined to what extent functions, as analysed in the philosophy of technical artefacts, can serve a role in explaining the aesthetic appreciation of these objects. The main conclusion is that, despite first appearances, so-called ‘Functional Beauty’ accounts cannot derive strength from analyses of artefact functions; on the contrary, these analyses constrain the possibilities for developing a suitable, function-based account of aesthetic appreciation. The paper follows a conceptual-engineering approach. After presenting desiderata for an account (...) of aesthetic appreciation, relevant insights are reviewed that are drawn from philosophical work on artefact functions. Combining the desiderata and insights, three major issues are identified that complicate the relation between function ascriptions to and aesthetic appreciation of technical artefacts. In closing, options are offered for resolving these complications or avoiding them altogether. (shrink)

Structural and functional descriptions of technical artefacts play an important role in engineering practice. A complete description of a technical artefact involves a description of both functional and structural features. Engineers, moreover, assume that there is an intimate relationship between the function and structure of technical artefacts and they reason from functional properties to structural ones and vice versa. This raises the question of how structural and functional descriptions are related. The kind of inference patterns that (...) establish coherence between structural and functional descriptions are explored in this paper, using the analysis of coherence creating relations of Thagard et al. Explanatory, analogical and practical inference patterns are discussed and it is argued that of these three, practical inferences may be the most important. Practical inferences, however, cannot provide a full underpinning of the coherence of structural and functional descriptions of technical artefacts. The paper ends with the suggestion that any account of the coherence of the structural and functional descriptions of technical artefacts must involve reference to their intentional features.Keywords: Technical artefact; Structural description; Functional description; Coherence relation; Practical inference.

In this paper I evaluate the ICE-theory of function ascriptions to technical artefacts as proposed by Houkes and Vermaas, 2004a and Houkes and Vermaas, 2004b. This account adds non-structural concepts to functional description of artefacts, which are typically not employed by engineers when they ascribe functions to artefacts. The aim of this paper is to analyse to what extent the ICE-theory can reproduce the engineering view that artefacts have their functions in virtue of their physicochemical structure. It is (...) shown that this theory can reproduce this engineering view for components of artefacts but not for the artefacts themselves: engineers can ascribe functions to components on the basis of only the physicochemical structure of artefacts; but when engineers ascribe functions to artefacts as a whole, they have to consider explicitly the goals for which agents use artefacts and the actions that constitute this use.Keywords: Function theory; Technical artefacts; Components; Physics and chemistry; Engineering; Action theory.

Looking for an adequate explication of the concept of a biological function, several authors have proposed to link function to design. Unfortunately, known explications of biological design in turn refer to functions. The concept of general design I will introduce here breaks up this circle. I specify design with respect to its ontogenetic role. This allows function to be based on design without making reference to the history of the design, or to the phylogeny of an organism, (...) while retaining the normative aspect of function ascriptions. The concept is applicable to the function and design of technical artifacts as well. Several problems well known with other definitions can be overcome by this approach. (shrink)

For several hundred thousand years, the genus homo deployed a characteristic technical creativity, communicating and transmitting its outcomes, together with its operative protocols, without the available recourse to articulated language. The thesis proposed here is that the aforementioned functions should be attributed to a complex intertwining of embodied abilities, which can in turn be ascribed to the classic philosophical concept of imagination. It is through imagination that the human becomes involved in material engagement, by virtue of which its extended (...) mind takes part in the processes of producing artifacts and is in turn shaped by them. The main issue of this article consists in investigating how this involvement occurs and the part that articulated language plays in it, following the invention of the latter. The latter’s emergence can indeed be traced back to the transformation and specialization of a recursive element, already present in the pre-linguistic work of imagination, whose ability to implement a denotative semantics is discussed in particular.

This paper looks at a genre of meetings that, while neither purely ‘scientific’ nor ‘diplomatic’, drew on elements from both professional spheres and gained prominence in the interwar decades and during the Second World War. It proposes to make sense of ‘technical conferences’ as a phenomenon that was made by and through scientific experts and politicians championing the organizing power of rationality, science and liberal internationalism. Against the background of swelling ranks of state-employed scientists, this paper documents the emergence (...) of technical conferences as the forums where they got down to work. To make this case the paper traces the influence of a new way of thinking about the function and organization of conferences, originating in the time around the First World War, on one international organization in particular: the United Nations Relief and Rehabilitation Administration (UNRRA), as a new hub of scientists and technicians.

This paper presents a possibilistic conception of technological artifacts facing technological determinism. Technological artifacts are considered points in a space of pragmatic possibilities determined by the abilities of different sociocultural aspects. The determination process of one possibility is the design of an artifact that comes true as long as the abilities are effective. A design is a process of creation at several levels of reality: material, functional, usefulness. At the same time, the idea of design may also include the social (...) participation of the community, which hereby collectively expresses its desires. This proposed alternative responds to determinism as well as to social constructivism. (shrink)

Analysis of the adequacy of engineering design methods, as well as analysis of the utility of concepts of function often invoked in these methods, is a neglected topic in both philosophy of technology and in engineering proper. In this paper, I present an approach—dubbed an explanationist perspective—for assessing the adequacy of function-based design methods. Engineering design is often intertwined with explanation, for instance, in reverse engineering and subsequent redesign, knowledge base-assisted designing, and diagnostic reasoning. I argue that the (...) presented approach is useful for validating function-based design methods with respect to their explanatory elements and that it supports assessment of the explanatory and design utility of “function”, and the different conceptualizations thereof, as used in such engineering design methods. I deploy two key desiderata from the explanation literature to assess the viability of function-based design methods: explanatorily relevant difference-making factors and counterfactual understanding defined in terms of what-if-things-had-been-different questions. I explicate the approach and its merits in terms of two case studies drawn from the engineering functional modeling literature: reverse engineering and redesign and malfunction analysis. I close the paper by discussing ramifications of the presented approach for the philosophy of design and the philosophy of explanation. (shrink)

This book is dedicated to a classic presentation of the theory of computable functions in the context of the foundations of mathematics. Part I motivates the study of computability with discussions and readings about the crisis in the foundations of mathematics in the early 20th century, while presenting the basic ideas of whole number, function, proof, and real number. Part II starts with readings from Turing and Post leading to the formal theory of recursive functions. Part III presents sufficient (...) formal logic to give a full development of Gödel's incompleteness theorems. Part IV considers the significance of the technical work with a discussion of Church's Thesis and readings on the foundations of mathematics. This new edition contains the timeline "Computability and Undecidability" as well as the essay "On mathematics". (shrink)

Much recent discussion has focused on the nature of artifacts, particularly on whether artifacts have essences. While the general consensus is that artifacts are at least intention-dependent, an equally common view is function essentialism about artifacts, the view that artifacts are essentially functional objects and that membership in an artifact kind is determined by a particular, shared function. This paper argues that function essentialism about artifacts is false. First, the two component conditions of function essentialism are (...) given a clear and precise formulation, after which counterexamples are offered to each. Second, ways to handle the counterexamples suggested by Randall Dipert and Simon Evnine are considered and rejected. Third, I then consider the prospects for restricting function essentialism to so-called technical artifacts, as Lynne Baker does, and argue that this, too, fails. This paper thereby consolidates the scattered literature on function essentialism and shows that, despite the seeming plausibility of the thesis, it should be rejected as an account of artifact essences.

The topic of this paper is the notion of technical (as opposed to biological) malfunction. It is shown how to form the property being a malfunctioning F from the property F and the property modifier malfunctioning (a mapping taking a property to a property). We present two interpretations of malfunctioning. Both interpretations agree that a malfunctioning F lacks the dispositional property of functioning as an F. However, its subsective interpretation entails that malfunctioning Fs are Fs, whereas its privative interpretation (...) entails that malfunctioning Fs are not Fs. We chart various of their respective logical consequences and discuss some of the philosophical implications of both interpretations. (shrink)

This volume handles in various perspectives the concept of function and the nature of functional explanations, topics much discussed since two major and conflicting accounts have been raised by Larry Wright and Robert Cummins’s papers in the 1970s. Here, both Wright’s ”etiological theory of functions’ and Cummins’s ”systemic’ conception of functions are refined and elaborated in the light of current scientific practice, with papers showing how the ”etiological’ theory faces several objections and may in reply be revisited, while its (...) counterpart became ever more sophisticated, as researchers discovered fresh applications for it. Relying on a firm knowledge of the original positions and debates, this volume presents cutting-edge research evincing the complexities that today pertain in function theory in various sciences. Alongside original papers from authors central to the controversy, work by emerging researchers taking novel perspectives will add to the potential avenues to be followed in the future. Not only does the book adopt no a priori assumptions about the scope of functional explanations, it also incorporates material from several very different scientific domains, e.g. neurosciences, ecology, or technology. In general, functions are implemented in mechanisms; and functional explanations in biology have often an essential relation with natural selection. These two basic claims set the stage for this book’s coverage of investigations concerning both ”functional’ explanations, and the ”metaphysics’ of functions. It casts new light on these claims, by testing them through their confrontation with scientific developments in biology, psychology, and recent developments concerning the metaphysics of realization. Rather than debating a single theory of functions, this book presents the richness of philosophical issues raised by functional discourse throughout the various sciences.​ Content Level » Research Keywords » Causal role theory of functions - Determination of content - Ecosystem selection - Etiological theory of function - Evolutionary biology - Functional explanations - Historical concepts in biology - Larry Wright - Neurosciences - New mechanism - Selected effects functions - Systemic theory of functions - William Wimsatt Related subjects » Anthropology & Archaeology - Epistemology & Philosophy of Science - Evolutionary & Developmental Biology - Neuroscience - Philosophy TABLE OF CONTENTS Introduction.- Section I.

The concept of technical function is a key concept to describe technical artifacts and artifacts-to-be-designed. Engineers often give such descriptions in terms of functional decomposition models, which represent relationships between functions and sets of other functions. Despite the importance of the concept of function there is no consensus among engineers about its meaning. Models of functional decomposition are likewise conceptually divergent. Although this conceptual diversity hampers information exchange between engineers, they accept and maintain it. Engineers do (...) not, by and large, engage in a focused debate to establish commonly shared functional conceptualizations. This contrasts with science where both debates on the adequacy of key conceptualizations and convergence toward shared conceptualizations are common. This book investigates the side-by-side usage of different functional decomposition models in engineering. It explains this phenomenon by applying and extending the analysis of theory choice in terms of methodological incommensurability to engineering functional decomposition, rather than to science. This analysis shows that engineers’ usage of competing functional decomposition models is rational from a practical point of view. This book furthermore investigates the communication problems that the side-by-side usage of different models engenders and presents a strategy that supports the exchange and re-use of functional information between engineers.

My aim is to question whether the introduction of new technologies in society may be considered to be genuine experiments. I will argue that they are not, at least not in the sense in which the notion of experiment is being used in the natural and social sciences. If the introduction of a new technology in society is interpreted as an experiment, then we are dealing with a notion of experiment that differs in an important respect from the notion of (...) experiment as used in the natural and social sciences. This difference shows itself most prominently when the functioning of the new technological system is not only dependent on technological hardware but also on social ‘software’, that is, on social institutions such as appropriate laws, and actions of operators of the new technological system. In those cases we are not dealing with ‘simply’ the introduction of a new technology, but with the introduction of a new socio-technical system. I will argue that if the introduction of a new socio-technical system is considered to be an experiment, then the relation between the experimenter and the system on which the experiment is performed differs significantly from the relation in traditional experiments in the natural and social sciences. In the latter experiments it is assumed that the experimenter is not part of the experimental system and is able to intervene in and control the experimental system from the outside. With regard to the introduction of new socio-technical systems the idea that there is an experimenter outside the socio-technical system who intervenes in and controls that system becomes problematic. From that perspective we are dealing with a different kind of experiment. (shrink)

In this paper we consider the implications for belief revision of weakening the logic under which belief sets are taken to be closed. A widely held view is that the usual belief revision functions are highly classical, especially in being driven by consistency. We show that, on the contrary, the standard representation theorems still hold for paraconsistent belief revision. Then we give conditions under which consistency is preserved by revisions, and we show that this modelling allows for the gradual revision (...) of inconsistency. (shrink)

_Purpose._ To substantiate the definition of technics as the attributive characteristics of a human being and the necessity of its orientation towards human flourishing in the context of new anthropological models of the 21st century. _Theoretical basis._ Correlation between technics, technology and the human essence is examined. The role of technics is traced at different historical stages of human development. Negative and positive effects of digital technology development upon a contemporary human being is analysed in the light of new anthropological (...) models: homo technologicus, homo digitalis and homo eudaimonicus. The content of a new worldview-value paradigm of defining goals of technology is outlined. _Originality._ Transformation of the role of technics correlates with value and worldview shifts in person’s understanding of his/her purpose in both natural and social worlds. Nowadays, philosophical analysis of anthropological dimension of technics and technology opens a horizon for seeking effective solutions in the face of the contemporary challenges and anti-utopian threats by means of focusing on the fact that, indeed, technological development is subordinate to the humanist goal that is flourishing, wellbeing and comprehensive development of a human being. _Conclusions._ The essence of technology reveals not through its functional but anthropogenic definitions in a sense of a source of institutionalization and in a sense of a source of realization of a human way of self-identification and self-objectification of human subjectivity. Technics/technology is the attributive characteristics of human essence and being: a human being is as much human as much he/she is a creator of technics. The purpose of technics is not to master the nature and to transform the world; technics is, above all, a tool of human self-improvement and self-creation through broadening the horizon of human capacities. The analysis of new modern anthropological models shows that it is the orientation of technology/technology towards human flourishing that is, on the one hand, a response to the existential demands of modern man, and on the other hand, a way of preventing future threats related to technological development.

The functional capabilities that consciousness seems to provide to biological systems can supply valuable principles in the design of more autonomous and robust technical systems. These functional concepts keep a notable similarity to those underlying the notion of operating system in software engineering, which allows us to specialize the computer metaphor for the mind into that of the operating system metaphor for consciousness. In this article, departing from these ideas and a model-based theoretical framework for cognition, we present an (...) architectural proposal for machine consciousness, called the Operative Mind. According to it, machine consciousness could be implemented as a set of services, in an operative system fashion, based on modeling of the own control architecture, that supervise the adequacy of the system architectural structure to the current objectives, triggering and managing adaptativity mechanisms.

We explore the technical details and historical evolution of Charles Peirce's articulation of a truth table in 1893, against the background of his investigation into the truth-functional analysis of propositions involving implication. In 1997, John Shosky discovered, on the verso of a page of the typed transcript of Bertrand Russell's 1912 lecture on ?The Philosophy of Logical Atomism? truth table matrices. The matrix for negation is Russell's, alongside of which is the matrix for material implication in the hand of (...) Ludwig Wittgenstein. It is shown that an unpublished manuscript identified as composed by Peirce in 1893 includes a truth table matrix that is equivalent to the matrix for material implication discovered by John Shosky. An unpublished manuscript by Peirce identified as having been composed in 1883?1884 in connection with the composition of Peirce's ?On the Algebra of Logic: A Contribution to the Philosophy of Notation? that appeared in the American Journal of Mathematics in 1885 includes an example of an indirect truth table for the conditional.

Aim of the paper is to present a new logic of technical malfunction. The need for this logic is motivated by a simple-sounding philosophical question: Is a malfunctioning corkscrew, which fails to uncork bottles, nonetheless a corkscrew? Or in general terms, is a malfunctioning F, which fails to do what Fs do, nonetheless an F? We argue that ‘malfunctioning’ denotes the modifier Malfunctioning rather than a property, and that the answer depends on whether Malfunctioning is subsective or privative. If (...) subsective, a malfunctioning F is an F; if privative, a malfunctioning F is not an F. An intensional logic is required to raise and answer the question, because modifiers operate directly on properties and not on sets or individuals. This new logic provides the formal tools to reason about technical malfunction by means of a logical analysis of the sentence “a is a malfunctioning F”. (shrink)

The purpose of this article is to establish that Lewis Mumford’s historical and philosophical writings were heavily influenced by the psychoanalytic theories of Sigmund Freud. It is argued that Freudian ideas and concepts played a foundational role in the construction of Mumford’s views on the nature and function of mind, culture and history, which in turn founded his views on the relationship between technology and society. Indeed, it is argued that a full understanding of Mumford’s technological writings cannot be (...) achieved until one has grasped their psychoanalytic influence. To this end, this article will reconstruct the psychological views of Lewis Mumford and indicate how they draw upon and modify Freudian theory. It will then be shown how Mumford’s theory of the psyche interacts with Mumford’s own concept of the idolum. This interaction, I will argue, considerably underpins Mumford’s holistic views on the relationship between society and the individual and between the internal and external world and will require us to reconsider our understanding of Mumford’s philosophy of technology, particularly with regard to his descriptions of monotechnics and biotechnics, the authoritarian and democratic technological forms. It will be argued that for Mumford the division intechnics corresponds to a division in the human psyche, and indeed arises from it. Not only will an appreciation of Mumford’s Freudian influence alter our understanding of Mumford’s technological writings in general, but also in particular it can enable us better to comprehend the reasoning behind Mumford’s recommended method of resistance to the modern power complex of the megamachine. Such a revised understanding of Mumford’s philosophy also undercuts any attempts to characterize his position as being a technological determinist one. Rather, his philosophy of technology is better understood as a form of technological voluntarism. (shrink)

The enduring influence of the architect Gottfried Semper derives primarily from his monumental theoretical foray Der Stil in der technischen und tektonischen Künsten, here translated into English for the first time. A richly illustrated survey of the technical arts, Semper's analysis of the preconditions of style forever changed the interpretative context for aesthetics, architecture, and art history. Style, Semper believed, should be governed by historical function, cultural affinities, creative free will, and the innate properties of each medium. Thus, (...) in an ambitious attempt to turn nineteenth-century artistic discussion away from historicism, aestheticism, and materialism, Semper developed in Der Stil a complex picture of stylistic change based on scrutiny of specific objects and a remarkable grasp of cultural variety. Harry Francis Mallgrave's introductory essay offers an account of Semper's life and work, a survey of Der Stil, and a fresh consideration of Semper's landmark study and its lasting significance.

This article contributes to contemporary philosophy of technology by carrying out a diffractive reading of Ernst Cassirer’s “Form und Technik” (1930) and Gilbert Simondon’s Du mode d’existence des objets techniques (1958). Both thinkers, who are here brought together for the first time, stood on the brink of the defining bifurcations of twentieth-century philosophy. However, in their endeavor to come to grips with the “being” of technology, Cassirer and Simondon, each in their own way, were prompted to develop an ontology of (...) emergence that gives ontological priority to “technicity,” that is, to technology considered in its efficacy or operative functioning. By reading Cassirer’s and Simondon’s insights through one another, we aim to further develop this ontology of emergence, and, simultaneously, to demonstrate the relevance of these thinkers for present-day theorizing. As we hope to show, the insistence on the ontological force of technological apparatuses transverses received philosophical and ontological divides and revitalizes the notions of “nature” and “the human,” which are now understood as coevolving with technology.

In fields where science and technology overlap, so do different function-ascriptions. The entities of Synthetic Biology research are a case in point, where organisms with biological functionality are altered to perform technical functions. A function theory for SynBiofacts has to address artifactual as well as biological functions of one and the same entity. Further demands on a function theory for Synthetic Biology emerge from methods of SynBiofact creation called kludging and the use-scenarios of SynBiofacts in proof-of-concept (...) research and BioArt. After discussing intentional accounts of technical functions, etiological function theory, contextual causation and contextual selection, a pluralist and weakly normative account of function will be outlined, that, or so it will be argued, can indeed cover all function ascriptions in Synthetic Biology. Lastly, some of the advantages and disadvantages of taking this stance will be outlined. (shrink)

As we hope to show, the insistence on the ontological force of technological apparatuses transverses received philosophical and ontological divides and revitalizes the notions of “nature” and “the human,” which are now understood as coevolving with technology.

The purpose of this article is to explore the close link between technology and death in the philosophical writings of Lewis Mumford. Mumford famously argued that throughout the history of western civilization we find intertwined two competing forms of technics; the democratic biotechnic form and the authoritarian monotechnic form. The former technics were said to be strongly compatible with an organic form of life while the latter were said to be allied to a mechanical power complex. What is perhaps less (...) well known is the extent to which Mumford characterizes the authoritarian technical form as being a technics of death. This article will argue that the connection between death and technics is a key theme in Mumford’s philosophy of technology. In addition to elaborating this theme and detailing how it informs Mumford’s other positions on the nature of technology, this article will also argue that Mumford’s theory of a technics of death bears witness, both implicitly and explicitly, to the influence of Sigmund Freud’s theory of the death instinct. Freud’s account of the death instinct will be outlined briefly and its influence on Mumford’s writings will be explained. Death, in Mumford’s technological writings, has a generally negative function and serves to warn humanity of the perilous course that its technological civilization is set upon. However it also has a positive function in that it encourages man to transcend its biological existence in acts of creativity and purpose. Death, in this positive sense, serves the purpose of life whereas, in the negative sense, it hinders it. The role of death, in both aspects, will be explored and related to Mumford’s overall perspective on technics and life. It is argued that Mumford’s philosophy of technology cannot be fully understood without an awareness of his views on death and its role in the life of technological society. (shrink)
