How Engineers Can Care from a Distance
Promoting Moral Sensitivity in Engineering Ethics Education
Moral (or ethical) sensitivity is widely viewed as a foundational learning goal in engineering ethics education. We have argued in this paper is that this view of moral sensitivity cannot be readily transported from the nursing context to the engineering context on the basis of a care-analogy. The particularized care characteristic of the nursing context is decisively different from the generalized and universalized forms of care characteristic of the engineering context. Through a focus on care and maintenance, the engineering student’s moral sensitivity can be refined, opening up a perceptual awakening and affectivity towards the complex nature of the engineer’s Other. This awakening is in part promoted through an understanding of the ideology of neutrality as a moment in the history engineering. Becoming aware of this ideology as an ideology can then be seen as an activity of dividing loyalties that allows for a reflexive and critical view of the biases and presuppositions inherited within the world of engineering. This process of deepening the engineering student’s moral sensitivity is perhaps as much a process of the student becoming aware of her professional world, how it shapes her understanding of herself, and what it means to be a good engineer.

Fostering responsible anticipation in engineering ethics education
How a multi-disciplinary enrichment of the responsible innovation framework can help
It is crucial for engineers to anticipate the socio-ethical impacts of emerging technologies. Such acts of anticipation are thoroughly normative and should be cultivated in engineering ethics education. In this paper we ask: ‘how do we anticipate the socio-ethical implications of emerging technologies responsibly?’ And ‘how can such responsible anticipation be taught?’ We offer a conceptual answer, building upon the framework of Responsible Innovation and its four core practices: anticipation, reflexivity, inclusion, and responsiveness. We forge a more explicit link between the practices of anticipation, reflexivity, and inclusion, while also enriching them with insights from disability studies, STS, design theory, and philosophy. On this basis we present responsible anticipation as an activity of reflective problem framing grounded in epistemic humility. Via the RI-practice of responsiveness we present responsible anticipation as a creative approach to engineering ethics, offering engineering students a critical yet productive perspective on how ethics may inform innovation.

Technology is no stranger to the city. Cities are planned, built, maintained, governed, demolished, and destroyed by technical means. Yet, the city has yet to receive much attention within the philosophy of technology. This volume addresses this gap, and in doing so contributes to the much-needed discussion on technology-enabled urban futures from the perspective of the philosophy of technology. In this introductory chapter, the larger volume is introduced by reflecting on the rationale and need for such a collection, sketching the main themes analyzed throughout, and providing an overview of the contributions.

Reimagining suggests the idea of opening up new, unconventional spaces of possibilities for an activity or an entity that already exists. This chapter sketches some ideas of the future of engineering in various aspects: designing, action, problem framing, professional and disciplinary identity, and the training of future engineers. The thoughts presented here are intended to be inconclusive. They take up and address the question of reimagining the future of engineering in order to inspire future dialogue between philosophers and engineers.

This paper undertakes a critical and constructive investigation into the applicability of value sensitive design (VSD) and design for values (DfV) methodologies for urban technologies, as a means to envision and enact responsible urban innovations. In particular, this paper focuses on the identification and analysis of values in urban technologies. First, an important methodological critique is highlighted, namely the vague articulation of ‘values' in VSD and DfV discourse. Next, cities are characterized as open, dynamic, and evolving systems, with ‘urban technologies’ as co-shapers of this process. This highlights the unique conditions requiring attention in order to arrive at a robust understanding of the relationship between values and urban technologies. Finally, these insights are combined to propose and sketch six heuristic principles aimed at surfacing and analysing values in urban technologies, offering a refinement of value-sensitive methodologies for the context of urban technological innovation.

Performing ethics of technology
Using improvisational performance-based techniques in engineering ethics education
The paper explores the potential for improvisational techniques used in ethics tutorials with the aim of fostering moral sensitivity. Recently there has been an increased interest in researching how performance-based techniques can foster certain ethical competencies. In ethics education for engineering, role-playing games have been an example of performance-based technique successfully employed to help students understand the complexities of ethical decision-making. However, role-playing games have several limitations because of the rigid structure of the roles and of choices in the script, which may lead students to act detached from the situation. Based on the idea that we need to foster also practice-based skills in engineering ethics education, not solely analytic skills, we have encountered in the previous literature the hypothesis that improvisation games can help students rehearse what it is like to act morally in an engineering situation. To clarify what is the potential of improvisation in engineering ethics education, we observed and helped with designing a course centred entirely on improvisational techniques for engineering and science students. Drawing from this pedagogical experiment, we noticed that improvisational performance-based techniques managed to stimulate the student’s moral sensitivity. This happened by two effects that we named the spectator effect and the shared space of vulnerability effect that we describe in detail. While role-playing has acquired the status of a “classical” exercise in engineering ethics education, improvisation still needs to be adopted by ethics teachers. Through our experiment, we hope to have shown that there is definitely an untapped potential in this kind of exercise for increasing student’s moral sensitivity and engagement, thus making possible an increased moral agency.

How to Teach Engineering Ethics?
A Retrospective and Prospective Sketch of TU Delft’s Approach to Engineering Ethics Education
This paper provides a retrospective and prospective overview of TU Delft’s approach to engineering ethics education. For over twenty years, the Ethics and Philosophy of Technology Section at TU Delft has been at the forefront of engineering ethics education, offering education to a wide range of engineering and design students. The approach developed at TU Delft is deeply informed by the research of the Section, which is centered around Responsible Research and Innovation, Design for Values, and Risk Ethics. These theoretical approaches are premised on the notion that technologies are inherently value-laden, and as such contain the possibility of fostering or hindering moral values. Each of these approaches encourages students to take a proactive attitude with respect to their projects and profession, thinking creatively about – and taking responsibility for – how to both prevent harm and do good via the technologies they help develop. To explain how this is put into practice, this paper sketches a brief history of ethics teaching at TU Delft, outlines current activities, and presents future plans for Bachelor and Master’s level engineering ethics education at TU Delft.

Towards a Darker Future?
Designing Environmental Values into the Next Generation of Streetlights
This paper examines the ethical dimensions of a critical urban infrastructure: streetlights. The development and proliferation of nighttime lighting has been fundamental and formative for urban nights, and streetlights constitute the primary source of illumination. Recent developments to lighting technologies, namely LEDs and ‘smart’ systems, are spurring a new generation of streetlights, with retrofits being rapidly undertaken around the world. While they may offer substantial energy savings, their long-term environmental effects are still under debate. Concurrent to these technological developments, the adverse costs and impacts of nighttime lighting—known as light pollution—have emerged as an ecological, economic, and ethical issue. This confluence of technological innovations and moral evaluations creates new challenges, but also an opportunity to envision and enact new strategies. For this, designing for darkness is presented as a value-sensitive framework for responsible lighting strategies that strives to incorporate and foster both substantive environmental values and meaningful nighttime experiences into the next generation of streetlights. First steps are taken to explore how this framework can be operationalized, and three design concepts are put forward as a means to create darker urban nights.

Normative design for society and anticipatory technology development
A double challenge for design research
This paper analyzes the increasing use of design tools and methods towards societal goals, and the interrelated approach to technology development it necessitates. Specifically, we argue that design research can assist in developing an anticipatory approach to technology development, which in turn widens future design possibilities. The paper proceeds in four steps. First, a distinction is made between different approaches to normative design, contrasting a precautionary approach (in which societal goals are constraints to design) from a directive approach (in which these goals are situated as design requirements). Second, a similar distinction between two types of normative technology development is made: precautionary (in which technology is created that safeguards societal goals) and directed (in which technology is created that realizes these goals). Third, an alternative approach to technology development is presented, aimed at enabling future technologies to realize precautionary or directed normative design for societal goals, termed anticipatory normative technology development. Such an anticipatory approach is thus conceptualized as an important enabler of normative design. Fourth, questions of how design research can support normative design is explored, highlighting two key roles: design research can create methods for normative design, and it can provide tools for anticipatory normative technology development that enables future normative design. Related to the latter, design research can draw from its established knowledge and methods for driving innovation. To contextualize this analysis, a running example is used throughout: The development of autonomous vehicles for reducing light pollution. Developing the navigation and sensors of autonomous vehicles to operate in low-light conditions is shown to anticipate an emerging social and environmental goal, thus creating the possibility for future normative design innovations.

LED Lighting Across Borders
Exploring the plea for darkness and value-sensitive design with Libbrecht’s comparative philosophy model
This chapter discusses how a comparative philosophical model can contribute to both substantive and procedural values in energy policy. We discuss the substantive values in the mainstream light-emitting diodes (LEDs) debate and Taylor Stone's alternative plea for darkness. We also explore Value Sensitive Design as a procedural approach. We conclude that the comparative philosophical model of Ulrich Libbrecht can appropriately broaden the set of substantive values used in VSD. We discuss the values of 'by-itself-so' and 'alter-intentionality', which come with the unforeseen necessity of accepting elements from other worldviews and of normativity in the procedural VSD approach.

Before Responsible Innovation
Teaching Anticipation as a Competency for Engineers
This paper focuses on engineering ethics education utilizing Responsible Innovation (RI). As a forward-looking approach aiming to embed ethics within innovation practices, RI strives to align technology development with societal values. However, when teaching the concepts and methods of RI, we face two intertwined challenges. First, RI presupposes we can estimate the consequences of an innovation or design intervention, while evidence shows it is nearly impossible to fully predict the consequences of new technologies. RI acknowledges this by replacing an ambition to predict with a call to anticipate innovation-consequences. However, without a robust account of anticipation this merely kicks the can down the road. Second, RI seems to suggest that we know what is meant by a specific value (e.g., privacy, sustainability) and its relation to a specific technology. While such knowledge is key to an anticipatory perspective, values are often treated superficially and a historically in RI literature. To address these challenges, we argue that RI-focused education – and engineering ethics generally – should be fostering historically informed anticipation as a core competency. To do so, we will define and characterize a set of interrelated virtues essential for engaging in historically informed anticipation: moral sensitivity (an ability to identify values at stake), epistemic humility (an awareness of the limits of one’s understanding), and moral imagination (an ability to envision new perspectives and solutions). We suggest this can be cultivated via a novel teaching method that involves an in-depth historically informed normative analysis of a value technology dynamic (called a value-genealogy of technology).

Legibility as a Design Principle
Surfacing Values in Sensing Technologies
This paper introduces the design principle of legibility as means to examine the epistemic and ethical conditions of sensing technologies. Emerging sensing technologies create new possibilities regarding what to measure, as well as how to analyze, interpret, and communicate said measurements. In doing so, they create ethical challenges for designers to navigate, specifically how the interpretation and communication of complex data affect moral values such as (user) autonomy. Contemporary sensing technologies require layers of mediation and exposition to render what they sense as intelligible and constructive to the end user, which is a value-laden design act. Legibility is positioned as both an evaluative lens and a design criterion, making it complimentary to existing frameworks such as value sensitive design. To concretize the notion of legibility, and understand how it could be utilized in both evaluative and anticipatory contexts, the case study of a vest embedded with sensors and an accompanying app for patients with chronic obstructive pulmonary disease is analyzed.

Driving in the Dark
Designing Autonomous Vehicles for Reducing Light Pollution
This paper proposes that autonomous vehicles should be designed to reduce light pollution. In support of this specific proposal, a moral assessment of autonomous vehicles more comprehensive than the dilemmatic life-and-death questions of trolley problem-style situations is presented. The paper therefore consists of two interre-lated arguments. The first is that autonomous vehicles are currently still a technol-ogy in development, and not one that has acquired its definitive shape, meaning the design of both the vehicles and the surrounding infrastructure is open-ended. Design for values is utilized to articulate a path forward, by which engineering ethics should strive to incorporate values into a technology during its development phase. Second, it is argued that nighttime lighting—a critical supporting infrastructure—should be a prima facie consideration for autonomous vehicles during their development phase. It is shown that a reduction in light pollution, and more boldly a better balance of lighting and darkness, can be achieved via the design of future autonomous vehicles. Two case studies are examined (parking lots and highways) through which autono-mous vehicles may be designed for “driving in the dark.” Nighttime lighting issues are thus inserted into a broader ethics of autonomous vehicles, while simultaneously introducing questions of autonomous vehicles into debates about light pollution.

Designing for Darkness
Urban Nighttime Lighting and Environmental Values
Artificial illumination has had profound and far-reaching impacts on the development, use, and perceptions of urban nights, and has brought with it many benefits. However, in recent years its adverse costs and effects – commonly referred to as light pollution – have emerged as a topic of concern. Nighttime lighting uses enormous amounts of energy, costs billions of dollars annually, can be detrimental to the health of humans and ecosystems, and cuts off access to a starry night sky. Addressing these impacts, and more fundamentally understanding the underlying values shaping contemporary discourse, is a complex and pressing challenge with moral, aesthetic, political, and technical dimensions. This dissertation takes up this challenge by offering a critical examination of the historical roots and normative presuppositions shaping the concept of light pollution. This critique leads to the proposal of an alternative normative framework: instead of focusing on reducing lighting, it argues for fostering darkness in urban nightscapes. A designing for darkness approach is developed on two interrelated levels. The first is conceptual, exploring the relationship between darkness, illumination, and environmental values. The second is practical, proposing first steps towards realizing darker nights via the responsible design of new and emerging technologies, namely LEDs and autonomous vehicles. Taken together, the chapters of this dissertation weave together a critical investigation and constructive contribution to a pressing urban challenge for the 21st century.

Re-envisioning the Nocturnal Sublime
On the Ethics and Aesthetics of Nighttime Lighting
Grounded in the practical problem of light pollution, this paper examines the aesthetic dimensions of urban and natural darkness, and its impact on how we perceive and evaluate nighttime lighting. It is argued that competing notions of the sublime, manifested through artificial illumination and the natural night sky respectively, reinforce a geographical dualism between cities and wilderness. To challenge this spatial differentiation, recent work in urban-focused environmental ethics, as well as environmental aesthetics, are utilized to envision the moral and aesthetic possibilities of a new urban nocturnal sublime. Through articulating the aspirations and constraints of a new urban nocturnal experience, this paper elucidates the axiological dimensions of light pollution, draws attention to nightscapes as a site of importance for urban-focused (environmental) philosophy, and examines the enduring relevance of the sublime for both the design of nighttime illumination and the appreciation of the night sky.

The Value of Darkness
A Moral Framework for Urban Nighttime Lighting
The adverse effects of artificial nighttime lighting, known as light pollution, are emerging as an important environmental issue. To address these effects, current scientific research focuses mainly on identifying what is bad or undesirable about certain types and uses of lighting at night. This paper adopts a value-sensitive approach, focusing instead on what is good about darkness at night. In doing so, it offers a first comprehensive analysis of the environmental value of darkness at night from within applied ethics. A design for values orientation is utilized to conceptualize, define, and categorize the ways in which value is derived from darkness. Nine values are identified and categorized via their type of good, temporal outlook, and spatial characteristics. Furthermore, these nine values are translated into prima facie moral obligations that should be incorporated into future design choices, policy-making, and innovations to nighttime lighting. Thus, the value of darkness is analyzed with the practical goal of informing future decision-making about urban nighttime lighting.

Light pollution
A case study in framing an environmental problem
Light pollution is a topic gaining importance and acceptance in environmental discourse. This concept provides a framework for categorizing the adverse effects of nighttime lighting, which advocacy groups and regulatory efforts are increasingly utilizing. However, the ethical significance of the concept has, thus far, received little critical reflection. In this paper, I analyze the moral implications of framing issues in nighttime lighting via the concept of light pollution. First, the moral and political importance of problem framing is discussed. Next, the origins and contemporary understandings of light pollution are presented. Finally, the normative limitations and practical ambiguities of light pollution are discussed, with the aim of strengthening the framework through which decisions about urban nighttime lighting strategies are increasingly approached.
