This document discusses the ideology of utilitarianism, which aims to maximize happiness and pleasure for all individuals in a society. However, it can be difficult to achieve happiness for all, as different people may have different views of what constitutes happiness. Pursuing individual pleasure too far could jeopardize others' happiness. While utilitarianism could be beneficial if a society agreed on what makes people happy, in reality one person's happiness may cause misery for others. The document provides some examples of how laws or policies aimed at achieving the greatest good for all could require some individuals to experience pain or unhappiness through actions like paying taxes or military service.
