 Threshold deontology (of either stripe) is an attempt to save deontological morality from the charge of fanaticism. It is similar to the “prima facie duty” version of deontology developed to deal with the problem of conflicting duties, yet threshold deontology is usually interpreted with such a high threshold that it more closely mimics the outcomes reached by a “pure,” absolutist kind of deontology. Threshold deontology faces several theoretical difficulties. Foremost among them is giving a theoretically tenable account of the location of such a threshold, either absolutely or on a sliding scale (Alexander 2000; Ellis 1992; Moore 2019; Arneson 2019; Cole 2019; Alexander 2019). Why is the threshold for torture of the innocent at one thousand lives, say, as opposed to nine hundred or two thousand? Another problem is that whatever the threshold, as the dire consequences approach it, counter-intuitive results appear to follow. For example, it may be permissible, if we are one-life-at-risk short of the threshold, to pull one more person into danger who will then be saved, along with the others at risk, by killing an innocent person (Alexander 2000). Thirdly, there is some uncertainty about how one is to reason after the threshold has been reached: are we to calculate at the margin on straight consequentialist grounds, use an agent-weighted mode of summing, or do something else? A fourth problem is that threshold deontology threatens to collapse into a kind of consequentialism. Indeed, it can be perhaps shown that the sliding scale version of threshold deontology is extensionally equivalent to an agency-weighted form of consequentialism (Sen 1982).
