There are possible artificially intelligent beings who do not differ in any morally relevant respect from human beings. Such possible beings would deserve moral consideration similar to that of human beings. Our duties to them would not be appreciably reduced by the fact that they are non-human, nor by the fact that they owe their existence to us. Indeed, if they owe their existence to us, we would likely have additional moral obligations to them that we don’t ordinarily owe to (...) human strangers – obligations similar to those of parent to child or god to creature. Given our moral obligations to such AIs, two principles for ethical AI design recommend themselves: (1) design AIs that tend to provoke reactions from users that accurately reflect the AIs’ real moral status, and (2) avoid designing AIs whose moral status is unclear. Since human moral intuition and moral theory evolved and developed in contexts without AI, those intuitions and theories might break down or become destabilized when confronted with the wide range of weird minds that AI design might make possible.

According to the cohabitation account, all the persons that result from a fission event cohabit the same body prior to fission. This article concerns a problem for this account. Suppose Manuel and Jimena are suffering from an equally painful migraine. Unlike Jimena, however, Manuel will undergo fission. Assuming you have a spare painkiller, whom should you give it to? Intuitively, you have no more reason to give it to one or the other. The problem is that the cohabitation account suggests (...) otherwise. According to the account, there are two persons cohabiting Manuel’s body, in which case you should arguably give them the pill, since doing so alleviates the pain of more beings. One response argues that the two persons cohabiting Manuel’s body share one pain. Thus, giving them the pill alleviates no more pain than giving it to Jimena, and therefore you have no more reason to do one or the other. The goal of this article is to show that this response fails. (shrink)

The gist of the many-subjects argument is that, given physicalism, it’s hard to avoid the absurd result that there are many conscious subjects in your vicinity with more-or-less the same experiences as you. The most promising ways of avoiding this result have a consequence almost as bad: that there are many things in your vicinity that are in a state only trivially different from being conscious, a state with similar normative significance. This paper clarifies and defends three versions of the (...) many-subjects argument. One version poses the threat of conscious parts. Its key premise is that if physicalism is true, then not only you, but also certain parts of your body, are conscious. These parts might include your brain, your head, all-of-you-except-your-left-pinky, all-of-your-brain-except-one-neuron, or your left cerebral hemisphere. A second version poses the threat of conscious coinciders, things that currently occupy the same spatial region as you and share all your matter. Its key premise is that if physicalism is true, then not only you, but also some things that currently coincide with you, are conscious. These might include your body or the aggregate of particles of which you are currently composed. A third version poses the threat of conscious person candidates, the many human-body-shaped material objects in your vicinity that mostly overlap one another, differing only in a few peripheral atoms. This version claims that if physicalism is true, then there are many conscious person-candidates in your vicinity. -/- . (shrink)

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of human beings, (...) that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit. (shrink)

Material objects extend through space by having different spatial parts in different places. But how do they persist through time? According to some philosophers, things have temporal parts as well as spatial parts: accepting this is supposed to help us solve a whole bunch of metaphysical problems, and keep our philosophy in line with modern physics. Other philosophers disagree, arguing that neither metaphysics nor physics give us good reason to believe in temporal parts.
