Libertarianism upholds individual liberty as of primary political importance. The concern for liberty leads to support for highly limited government, and sometimes even anarchism. Sometimes people come under the mistaken impression that libertarians have such a myopic concern for individual liberty that they must oppose social rules and social order. While that is too extreme, libertarianism does seem to have significant tensions with social rules, and the role of social rules within libertarianism is complex and contentious. This work aims to (...) bring out some of this complexity and to clarify the important place of social rules in libertarian thought. (shrink)

Much has been written about climate change from an ethical view in general, but less has been written about it from a libertarian point of view in particular. In this paper, I apply the libertarian moral theory to the problem of climate change. I focus on libertarianism’s implications for our individual emissions. I argue that even if our individual emissions cause no harm to others, these emissions cross other people’s boundaries, although the boundary-crossings that are due to our ‘subsistence emissions’ (...) are implicitly consented to by others, there is no such consent to our ‘non-subsistence emissions’, and there is no independent justification for these emissions. Although offsetting would provide such a justification, most emitters do not offset their non-subsistence emissions. Therefore, these emissions violate people’s rights, which means that they are impermissible according to libertarianism’s non-aggression principle. (shrink)

Libertarianism holds that agents initially fully own themselves and have moral powers to acquire property rights in external things under certain conditions. It is normally advocated as a theory of justice in the sense of the duties that we owe each other. So understood, it is silent about any impersonal duties (i.e., duties owed to no one) that we may have.
