 Foot (1978, 1984, 1985) argues that the moral relevance of the doing /allowing distinction rests on a distinction between positive and negative rights. Negative rights are rights against interference whereas positive rights are rights to aid or support. Negative rights are, in general, stronger than positive rights: it typically takes more to justify an interference than to justify the withholding of goods and services. Foot connects this to her analysis of the doing/allowing distinction by arguing that interference implies breaking into an existing sequence and initiating a new one and that therefore violation of a right of non-interference must involve doing, rather than merely allowing, harm (Foot, 1984, 284).
