It has sometimes been claimed (usually without evidence) that the harm caused by an individual's participation in a greenhouse-gas-intensive economy is negligible. Using data from several contemporary sources, this paper attempts to estimate the harm done by an average American. This estimate is crude, and further refinements are surely needed. But the upshot is that the average American is responsible, through his/her greenhouse gas emissions, for the suffering and/or deaths of one or two future people.

Most people believe that it is permissible to kill a nonresponsible threat, or someone who threatens one's life without exercising agency. Defenders of this view must show that there is a morally relevant difference between nonresponsible threats and innocent bystanders. Some philosophers, including Jonathan Quong and Helen Frowe, have attempted to do this by arguing that one who kills a bystander takes advantage of another person, while one who kills a threat does not. In this paper, I show that the (...) proposals offered by Quong and Frowe have unacceptable implications. I then argue that those who claim that nonresponsible threats may be killed face a dilemma generated by the possibility of a stationary threat, or someone who endangers another person's life without moving. Unless we arbitrarily distinguish between stationary and moving nonresponsible threats, it is unclear how the permission to kill nonresponsible threats is to be explicated. I conclude that nonresponsible threats are not legitimate targets of self-defence. (shrink)

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)
