I take issue with the view that libertarian theory does not imply any particular stand on abortion. Liberty is the absence of interference with people’s wills—interests, wishes, and desires. Only entities that have such are eligible for the direct rights of libertarian theory. Foetuses do not; and if aborted, there is then no future person whose rights are violated. Hence the “liberal” view of abortion: women (especially) may decide whether to bear the children they have conceived. Birth is a good (...) dividing line between the freedom to abort and the point at which society is permitted to take an interest. Once born, children detach from their mothers; no invasion of their bodies is necessary to separate them. Yet some ways of bringing them up can have a negative impact on society. There is a thus legitimate interest in protecting ourselves from the results of truly bad parenting. (shrink)

This paper aims to state the obvious – the commonsense, rational approach to child-producing. We have no general obligation to promote either the “general happiness” or the equalization of this and that. We have children if we want them, if their life prospects are decent – and if we can afford them, which is a considerable part of their life prospects being OK – and provided that in doing so we do not inflict injury on others. It’s extremely difficult to (...) do this latter, but affording them, in rich countries, is another matter. With that qualification, by and large people should just go ahead and have (or not have) children – as many as they think they want and can handle – as it suits them. (shrink)
