A common assumption is that psychological egoism, the view that a person can do an act only if she believes that the act is in her interest, combined with ought-implies-can, the view that a person morally ought to do an act only if she can do it, entails the view – call it OIB – that a person morally ought to do an act only if she believes that the act is in her interest. I argue that psychological egoism and ought-implies-can, interpreted fairly, use “can” in different ways; consequently, they do not entail OIB. They entail something similar to OIB, but not OIB itself. From these facts several significant results follow, each concerning arguments or assumptions about psychological, ethical, or rational egoism. For instance, they undermine the view that psychological egoism rules out those other two forms of egoism.

Melina Constantine Bell (2021) argues that J. S. Mill's harm principle permits society to coercively interfere with the use of bigoted insults, since these insults are harmful on “a more expansive, modern, conception of harm.” According to Bell, these insults are harmful in virtue of their contributing to detrimental objective states like health problems. I argue that people with illiberal dispositions might have intense and sustained negative subjective reactions to behavior that the harm principle ought to protect, reactions intense enough to affect their health or other objective interests. Bell's way of thinking about harm therefore has illiberal implications. Yet I agree with her that bigoted insults should be regarded as harmful. I therefore propose an alternative way of understanding harm according to which subjective pain is a harm when it is intentionally caused.

Daniel Immerman has recently put forward a novel account of harm, the Worse than Nothing Account. We argue that this account faces fatal problems in cases in which an agent performs several simultaneous actions. We also argue that our criticism is considerably more powerful than another one that has recently been advanced.

Climate change is to a large extent a collective action problem, but many believe that individual action is also required. But what if no individual contribution to climate change is necessary nor sufficient to cause climate change-induced harms? This issue is known as the problem of inconsequentialism. It is particularly problematic for act consequentialism because the theory does not seem to judge such inconsequential contributions negatively. In this paper, we apply Henry Sidgwick's idea of esoteric morality to climate change and assess whether what we call a climate esoteric morality could help to deal with the problem of inconsequentialism from an act consequentialist perspective. Consequentialists ought then to promote what we call nonconsequentialist faux principles; exaggerate existing consequentialist principles that pro tanto forbid contributing to climate change whenever strictly consequentialist principles fail to do so; and refrain from criticising nonconsequentialist principles that forbid contributing to climate change.
