 In answer to the question, ‘What does well-being consist in?’, then, the hedonist will answer, ‘The greatest balance of pleasure over pain’. We might call this substantive hedonism. A complete hedonist position will involve also explanatory hedonism, which consists in an answer to the following question: ‘What makes pleasure good, and pain bad?’, that answer being, ‘The pleasantness of pleasure, and the painfulness of pain’. Consider a substantive hedonist who believed that what makes pleasure good for us is that it fulfills our nature. This theorist is not an explanatory hedonist.
