This module discusses the responsibility of engineers. We will investigate what exactly responsibility is, distinguishing between passive responsibility for things that happened in the past and active responsibility for things not yet attained. Furthermore, we will discuss the professional responsibility of engineers, examine the consequences for this responsibility, such as whistle-blowing and the application of the precautionary principle.

In this module, we discuss the role of codes of conduct in engineering. In particular, we focus on professional codes as they have been proposed by professional engineering societies and on corporate codes, as they have been formulated by companies. We discuss these two types of codes, their structure and their content, and a number of common objections that have been levelled against codes of conduct. This includes the problem that someone is acting according to the code, but that it may nevertheless lead to dismissal.

In this module we will discuss some ethical theories that have been developed by various philosophers. Ethical theories help us to sort out our thinking and to develop a coherent and justifiable basis for dealing with moral questions. The role of ethical theories is to provide certain arguments or reasons for a moral judgment. They provide a normative framework for understanding and responding to moral problems, so improving ethical decision-making or, at least, avoiding certain shortcuts, such as neglecting certain relevant features of the problem or just stating an opinion without any justification. In this module we shall therefore introduce three of the most well-known ethical theories: consequentialism, duty ethics and virtue ethics. These theories each have their own criteria with which they determine whether an action is right or wrong. Before we go into these three theories we shall discuss what we mean by morality and ethics, and we shall look into the points of departure of ethics: values, norms, and virtues. These points of departure often recur in ethical theories.

Engineers will encounter in their professional life some difficult moral situations. Such situations call for moral judgment, using the tools we have introduced in the preceding modules. However, moral judgment is not a straightforward or linear process in which you simply apply ethical theories to find out what to do. Instead it is a process in which the formulation of the moral problem, the formulation of possible ‘solutions’, and the ethical judging of these solutions go hand in hand. This messy character of moral problems, however, does not rule out a systematic approach. In this module we describe a systematic approach to problem solving that does justice to the complex nature of moral problems and moral judgment: the ethical cycle. Our goal is to provide a structured method of addressing moral problems which helps to guide a sound analysis of these problems.
