Ezio Di Nucci

In a previous paper, I had argued that Strong’s counterexamples to Marquis’s argument against abortion—according to which terminating fetuses is wrong because it deprives them of a valuable future—fail either because they have no bearing on Marquis’s argument or because they make unacceptable claims about what constitutes a valuable future. In this paper I respond to Strong’s criticism of my argument according to which I fail to acknowledge that Marquis uses "future like ours" and "valuable future" interchangeably. I show that my argument does not rely on not acknowledging that "future like ours" and "valuable future" are interchangeable; and that, rather, it is exactly by replacing "future like ours" with "valuable future" that I construct my argument against Strong. I conclude with some remarks on how Marquis’s concept of "future like ours" should be interpreted.

Thinking is overrated: golfers perform best when distracted and under pressure; firefighters make the right calls without a clue as to why; and you are yourself ill advised to look at your steps as you go down the stairs, or to try and remember your pin number before typing it in. Just do it, mindlessly. Both empirical psychologists and the common man have long worked out that thinking is often a bad idea, but philosophers still hang on to an intellectualist picture of human action. This book challenges that picture and calls on philosophers to wake up to the power of mindlessness: it is our habits, skills and conventions that help us cope with a world way too diverse for us to hope to always reinterpret it. The book presents the empirical evidence that has been accumulating over the last few decades and offers a philosophical analysis of mindless phenomena such as habits, skilled activity, automatic actions, emotional and spontaneous reactions and social conventions, arguing that traditional philosophical theories of action should be revised to do justice to this forgotten but important part of our lives: when we act mindlessly, we are free and fully rational even though we neither deliberate nor are aware of what we are doing.

I argue against the Doctrine of Double Effect’s explanation of the moral difference between terror bombing and strategic bombing. I show that the standard thought-experiment of Terror Bomber and Strategic Bomber which dominates this debate is underdetermined in three crucial respects: (1) the non-psychological worlds of Terror Bomber and Strategic Bomber; (2) the psychologies of Terror Bomber and Strategic Bomber; and (3) the structure of the thought-experiment, especially in relation to its similarity with the Trolley Problem. (1) If the two worlds are not identical, then it may be these differences between the two worlds and not the Doctrine of Double Effect to explain the moral difference; (2a) if Terror Bomber and Strategic Bomber have the same causal beliefs, then why does Terror Bomber set out to kill the children? It may then be this unwarranted and immoral choice and not the Doctrine of Double Effect that explains the moral difference; (2b) if the two have different causal beliefs, then we can’t rule out the counterfactual that, had Strategic Bomber had the same beliefs as Terror Bomber, she would have also acted as Terror Bomber did. Finally, (3) the Strategic Bomber scenario could also be constructed so as to be structurally equivalent to the Fat Man scenario in the Trolley Problem: but then the Doctrine of Double Effect would give different answers to two symmetrical cases.

There are some interesting similarities between Aristotle’s ‘mixed actions’ in Book III of the Nicomachean Ethics and the actions often thought to be justifiable with the Doctrine of Double Effect. Here I analyse these similarities by comparing Aristotle’s examples of mixed actions with standard cases from the literature on double effect such as, amongst others, strategic bombing, the trolley problem, and craniotomy. I find that, despite some common features such as the dilemmatic structure and the inevitability of a bad effect, Aristotle’s mixed actions do not count as cases justifiable through application of the Doctrine of Double Effect because they fail to meet the crucial necessary condition of the Doctrine according to which the bad effect can only be a merely foreseen side-effect and not an intended means.

Ethics Without Intention tackles the questions raised by difficult moral dilemmas by providing a critical analysis of double effect and its most common ethical and political applications. The book discusses the philosophical distinction between intended harm and foreseen but unintended harm. This distinction, which, according to the doctrine of double effect, makes a difference to the moral justification of actions, is widely applied to some of the most controversial ethical and political questions of our time: collateral damages in wars and acts of terrorism; palliative care, euthanasia, abortion, and embryo research; self-defence, suicide, and self-sacrifice. It is also crucial to the now notorious theoretical cases of the trolley problem and the knobe effect. Di Nucci approaches the doctrine of double effect from four key directions: its historical origins, which can be traced further back than the classic attribution to Aquinas; its theoretical coherence, which is the subject of a lively contemporary debate in philosophy; its moral intuitiveness, which has always been taken for granted but has recently begun to be questioned; and finally its relevance to the difficult moral and political decisions of our time. An engaging and comprehensive introduction to the doctrine of double effect.
