Robert Harles was a renowned British philosopher and economist who lived in the 18th century. He is best known for his work on the concept of utilitarianism, which he developed in his book An Introduction to the Principles of Morals and Legislation. Harles argued that the greatest good for the greatest number of people should be the basis for all moral decisions. He believed that the pursuit of pleasure and the avoidance of pain should be the guiding principles of morality. He also argued that the government should be responsible for providing the greatest good for the greatest number of people. Harles' work had a major influence on the development of modern economics and political philosophy. He is remembered as one of the most influential thinkers of the Enlightenment period. His ideas continue to be studied and discussed today, and his work has been cited by many modern philosophers.
