Looking at the fifth chapter of Mill’s ‘Utilitarianism’ in more depth, we can deduce many ideas that also relate to the war on Iraq and whether it is a ‘just’ or ethical war. The first section of the chapter is largely descriptive as Mill begins by saying that throughout history, one of the major obstacles to the reception of utility has been that it does not tolerate a supposition of justice. Whether or not the justice or injustice of an act is something inherent and separate from questions of utility is what Mill attempts to determine in the chapter.Mill commences by attempting to pinpoint the definition of justice, by coming up with a list of things that are often described as just or unjust. In trying to define justice, Mill considers many factors, including legal rights, deprivation of something someone has a moral right to possess, whether a person receives what they deserve or not, violating agreements, the injustice of preferentialism in improper situations, and finally the notion of equality as an element of justice. In the mainly descriptive first part of the chapter, Mill counters the assertion that utilitarianism is opposed to justice. He mainly writes about the classification of justice and its origins historically and it is also noteworthy that Mill does not offer his own conjecture about what is required for justice. From Mill’s point of view, justice is not a theoretical model so much as it is a feeling about morality that lots of people possess. As a result, in defining justice Mill studies what other people denote by the term. He concludes that justice exists for the reason that people believe it does, and it means what they consider it to mean. Beginning at the accepted understanding of justice, Mill envisages what associates a different set of ideas about the theory. Subsequently, he puts forward that they are amalgamated by the concept of rights, an idea he brings in through his claims about ‘perfect obligation’. For Mill, a right insinuates that an individual has a legitimate entitlement that the social order is to guard them against any desecration. Many advocates of utilitarianism write off the idea of rights, and many debates about the subject are based around whether rights do actually exist, but Mill held a different perspective.
