Step-by-step explanation:
Utilitarianism is a moral philosophy that focuses on promoting the greatest happiness or utility for the greatest number of people. Utilitarians believe that the right action is the one that results in the most overall happiness and satisfaction. The measure of happiness, satisfaction, and pleasure in life is subjective and varies from person to person. Therefore, each individual may have a different perspective on how they view their own happiness, satisfaction, and pleasure in life. Moreover, the principle of utility suggests that moral conduct is that which maximizes the good for the most people, leading to different approaches to calculating and maximizing 'utility' depending on the complexity of the situation.
