John Stuart Mill was a utilitarian from 19th Century England. He has written On Liberty, Utilitarianism, and The Subjection of Women.
He explained in the first chapter that individual liberty, while it does apply to women and men alike, it does not apply to children or “barbarian” races. He believes in benevolent imperialism of lesser races, but liberty for any adult who is “civilized”.
Please do keep in mind, what he argues is still relatively progressive for the year 1859.
Mill would be considered a libertarian today, based on this essay. He believes in very little government involvement, unless someone is harming someone else and/or society.
Utilitarianism is the theory that people should do what makes them happy, but especially if it creates a general goodness and happiness in society. Utilitarianism does not necessarily mean doing whatever you want regardless of the consequences.
It is not doing things that feel good at the time, binge-eating, binge-drinking, unprotected and copious amounts of sex with strangers. These actions do not crate a general good. They are damaging to the health of yourself and others. Utility is pleasure in the absence of pain. Poor health causes pain. So going on a drinking bender all the time, while it gives you some pleasure at the time, makes a higher level of happiness impossible, and it harms yourself and others.
However, if you see someone damaging their physical, emotional, mental, or financial health, there is nothing you can do, argues Mill. However, if the person is an abusive drunk and harms you or anyone else, it becomes a legal case.
As for the essay, I thought it was well-written. The English was not too archaic. It was an interesting read. I don’t agree with everything in the essay, but generally it is aligned with my views on what liberty is.
