Jeremy Bentham is widely regarded as the founder of utilitarianism, a school of thought in ethics that emphasizes the importance of maximizing overall happiness or pleasure.

The fundamental principle of utilitarianism is that the morally right action is the one that produces the greatest amount of happiness or pleasure for the greatest number of people.

The primary objective of utilitarianism is to maximize the overall happiness or pleasure of all affected individuals, regardless of their individual circumstances or interests.

The term 'the greatest happiness principle' is commonly used to refer to the fundamental principle of utilitarianism, which emphasizes the importance of maximizing overall happiness or pleasure.

In utilitarianism, the rightness or wrongness of an action is determined primarily by its consequences and their impact on the overall happiness or pleasure of those affected.

One of the main criticisms of utilitarianism is that it tends to overlook the importance of individual rights and liberties, as it prioritizes the maximization of overall happiness, which may sometimes come at the expense of individual autonomy or well-being.

John Rawls is renowned for his critique of utilitarianism and his introduction of the 'veil of ignorance' thought experiment, which aims to ensure that moral principles are fair and just by disregarding individual knowledge of their own circumstances and interests.

The 'veil of ignorance' thought experiment is a hypothetical situation in which individuals are asked to make decisions about moral principles without knowing their own personal characteristics, circumstances, or interests, thereby promoting fairness and impartiality.

In utilitarianism, the primary consideration when making moral decisions is the maximization of overall happiness or pleasure for all affected individuals.

Act utilitarianism evaluates the rightness or wrongness of individual actions based on their consequences, while rule utilitarianism assesses the morality of actions by considering the consequences of following general rules or principles.

Immanuel Kant criticized the greatest happiness principle, arguing that it is too vague and subjective to serve as a reliable guide for moral decision-making.

The 'hedonic calculus' is a hypothetical method proposed by Jeremy Bentham for measuring and comparing different types of happiness or pleasure.

In utilitarianism, individual rights and liberties are generally considered important, but they can be overridden in certain situations if doing so would result in a greater overall happiness or pleasure.

John Rawls criticized the greatest happiness principle, arguing that it fails to consider the distribution of happiness and may lead to unjust outcomes, where the happiness of some individuals is sacrificed for the sake of maximizing the overall happiness.

The 'paradox of hedonism' is the idea that pursuing pleasure as the ultimate goal can ironically lead to unhappiness, as it may result in a constant state of desire and dissatisfaction.
