In JS Mill's book On Liberty in chapter four, "On the Limits on the Authority of Society over the Individual", Mill focuses on how every member of society should not harm others and how everyone is obliged to ensure the safety of society by maintaining a balance. However, as Mill explains in this chapter, society then has the right to punish those members who harm society. If the level of harm is high the law will be used and if the level of harm is lower then the public can scrutinize that person but the law will not intervene. Mill has various ideas that support his argument, but he also considered some objections to his argument. In chapter four of J. S. Mill's On Liberty, Mill argues that there must be a strong division between the rights of individuals and the capacity of society to punish. He believes that the “harm principle” will hold individuals accountable for their actions, thereby preventing harm. to others, however there are also flaws in Mill's argument all of which will be discussed in this essay. Mill asserts in his book, On Liberty, saying: “The disadvantages which are strictly inseparable from the unfavorable judgment of others are the only ones. to which a person should always be subject in that part of his conduct which concerns his own good, but which does not affect the interests of others in their relations with him. Acts harmful to others require entirely different treatment. (Page 72, Mill) This quote summarizes his harm principle, which states that in society, each individual cannot violate the rights of others or harm them in any way, but if it only affects him to itself, society cannot punish the individual. Mill explains how society will judge even if the person only harms themselves and has enough paper, which is a huge objection to Mill's argument.
