Singer Replacability Argument

The Replaceability argument allows the killing of sentient beings who are hindered by their inability to conceptualise an existence in the future (Singer, p.94-95). Provided such beings lead a pleasant life and are killed painlessly, they ought to be replaced by those who would have equally pleasant lives (Unit reader, pg. 69). I will be arguing that Singer's theory is flawed because it fails to individuate entities with moral status, by treating them as mere 'receptacles' of value and as a means to an end. This paper begins by examining Singer's overall ethical theory and his reasons for the replacability claim. I will then illustrate that his premise also supports the replaceability of humans, those particularly who are not as mentally capable …show more content…

While Singer's argument justifies eating merely sentient animals, his premise would also warrant harming and eating human infants, dementia patients or cognitively disabled human beings. Unless of course, you are a Speciesist who favour's their own species, without moral justification, whilst harming and exploiting members of other species (Unit reader pg.66-67). If we consider perhaps how humans might react to Super Advanced extra-terrestrial beings who arrive on earth to raise and kill humans for food, one might begin to understand the unjustifiability of the replaceability argument, and on a greater level, the killing of innocent beings in factory farming. Singer's Principle of Equality theory also runs into a problem. Although the theory contends that all beings with preferences should have those preference considered equally (Unit reader pg. 60-61), if we go ahead and take animals out of the question, we must then also give unequal consideration to different human beings such as the human infant or the dementia patient mentioned above. This would go against the theory of equality in which all human's preferences/interests are considered
