John Stuart Mill

Utilitarianism: This is a philosophical belief that actions are right if they benefit the majority. It's like choosing a family vacation destination based on what most family members want.

Liberalism: A political ideology that values individual freedoms, equality, democracy, and human rights. It's like being at a buffet where everyone can choose what they want to eat without restrictions.

Political Economy: The study of production and trade and their relations with law, custom, and government. It's like looking at how all parts of a car work together - from engine design (production) to fuel consumption (trade) - under different driving rules (law), driving habits (custom), and traffic regulations (government).
