In this paper, we present and defend an analysis of harm that we call the Negative Influence on Well-Being Account (NIWA). We argue that NIWA has a number of significant advantages compared to its two main rivals, the Counterfactual Comparative Account (CCA) and the Causal Account (CA), and that it also helps explain why those views go wrong. In addition, we defend NIWA against a class of likely objections, and consider its implications for several questions about harm and its role (...) in normative theorizing. (shrink)

As autonomous systems rapidly become ubiquitous, there is a growing need for a legal and regulatory framework that addresses when and how such a system harms someone. There have been several attempts within the philosophy literature to define harm, but none of them has proven capable of dealing with the many examples that have been presented, leading some to suggest that the notion of harm should be abandoned and “replaced by more well-behaved notions”. As harm is generally something that is (...) caused, most of these definitions have involved causality at some level. Yet surprisingly, none of them makes use of causal models and the definitions of actual causality that they can express. In this paper, which is an expanded version of the conference paper Beckers et al. (Neurips, 2022), we formally define a qualitative notion of harm that uses causal models and is based on a well-known definition of actual causality. The key features of our definition are that it is based on contrastive causation and uses a default utility to which the utility of actual outcomes is compared. We show that our definition is able to handle the examples from the literature, and illustrate its importance for reasoning about situations involving autonomous systems. (shrink)

A popular view of harming is the causal account (CA), on which harming is causing harm. CA has several attractive features. In particular, it appears well equipped to deal with the most important problems for its main competitor, the counterfactual comparative account (CCA). However, we argue that, despite its advantages, CA is ultimately an unacceptable theory of harming. Indeed, while CA avoids several counterexamples to CCA, it is vulnerable to close variants of some of the problems that beset CCA.

In a typical non-identity case, the agent performs an action that causes someone to exist at a low but positive level of well-being, although an alternative was to create another, much happier person instead. There seem to be strong moral reasons against what the agent does, but it is difficult to explain how this can be so. In particular, it seems that on a simple counterfactual account of harm, the action does not harm anyone, as it does not make anyone (...) worse off than he or she would have been had the action not been performed. In this paper, I criticize the response that the action nevertheless harms the actual child, as well as the response that it makes the counterfactual child worse off. I argue that the following alternative view deserves attention: a compound of the actual and the counterfactual child is made worse off by the action. (shrink)

The ‘non-identity problem’ raises a well-known challenge to the person-affecting view, according to which an action can be wrong only if it affects someone for the worse. In a recent article, however, Thomas D. Bontly proposes a novel way to solve the non-identity problem in person-affecting terms. Bontly's argument is based on a contrastive causal account of harm. In this response, we argue that Bontly's argument fails even assuming that the contrastive causal account is correct.

Do we owe it to future generations, as a requirement of justice, to take action to mitigate anthropogenic climate change? This paper examines the implications of Derek Parfit’s notorious non-identity problem for that question. An argument from Jörg Tremmel that the non-identity effect of climate policy is “insignificant” is examined and found wanting, and a contrastive, difference-making approach for comparing different choices’ non-identity effects is developed. Using the approach, it is argued that the non-identity effect of a given policy response (...) to climate change depends on the contrasting policy. Compared to a baseline scenario without further mitigation, the non-identity effect of choosing to limit climate change to 1.5°C would be highly significant. (shrink)

The counterfactual comparative account of harm and benefit has several virtues, but it also faces serious problems. I argue that CCA is incompatible with the prudential and moral relevance of harm and benefit. Some possible ways to revise or restrict CCA, in order to avoid this conclusion, are discussed and found wanting. Finally, I try to show that appealing to the context-sensitivity of counterfactuals, or to the alleged contrastive nature of harm and benefit, does not provide a solution.
