Utilitarianism summary

At the core of Mill's philosophy lies this deceptively simple idea: that the rightness of any action depends on the amount of happiness it produces. This is the essence of the pleasure principle, and it's a concept that the author explores in great depth.

Pleasure and pain are, according to Mill, the ultimate indicators of what is good and what is bad. He argues that we all naturally seek pleasure and avoid pain, and that this basic human impulse can serve as a reliable guide for moral decision-making. When faced with a choice between two actions, Mill suggests that people should always choose the one that will result in the greatest overall happiness for everyone affected.

The idea of utilitarianism challenges the long-held notion that moral decision-making should be based solely on rigid, inflexible rules dictated by tradition, custom, or religion. Instead, guiding principles should promote the overall happiness and well-being of both individuals and society.

At the heart of Mill's argument is the idea that any principle that opposes utility – that is, the maximum happiness for the greatest number of people – must be fundamentally flawed. Consider the belief that some people are inherently more deserving of happiness than others. This belief is still flourishing in some aristocratic societies, where the wealthy and powerful are seen as having a divine right to rule. In a modern, democratic world, utilitarianism holds such a belief as not only irrational but deeply unjust.

If religion, tradition, and custom are no longer an adequate basis for ethical decisions in society, then what about the justice system, which has for centuries followed religious or traditional punishments to enforce a so-called greater good? In utilitarianism, the principles that should guide a just and ethical society, lie in the concept of proportionality. 

According to this idea, the severity of any punishment or consequence should be commensurate with the harm caused by the offense in question. A person who commits a relatively minor infraction, like stealing a loaf of bread to feed their family, should not be subject to the same level of punishment as someone who commits a far more serious crime, like murder or assault.

The world of ethics stretches far beyond the world of criminal or social justice, and any moral system has to account for how life is actually lived: by individuals, who face complicated decisions every single day. So utilitarianism, to be useful itself, has to be put into daily practice. To find out more, let’s take a closer look.

For a moment, imagine you're a doctor working in a busy hospital during a flu pandemic. The hospital is running dangerously low on ventilators, and you're faced with a heartbreaking decision. Two patients, both critically ill, are in desperate need of a ventilator to survive. One is a young mother with two small children at home, while the other is an elderly man with a history of health problems. With only one ventilator available, you must choose which patient to save.
