What does Mill think about Utilitarian happiness?

John Stuart Mill believes that utilitarian happiness should be understood as a qualitative rather than merely quantitative measure of pleasure. He argues that higher pleasures, such as intellectual and moral satisfactions, are superior to lower, more base pleasures. Mill contends that the pursuit of happiness should consider the well-being of all individuals, emphasizing the importance of justice and individual rights in achieving the greatest happiness for the greatest number. Thus, for Mill, true happiness encompasses both the quantity and quality of pleasures experienced by individuals.
