What is ethical egoism and utilitarianism

Ethical egoism is the philosophy that individuals should act in their own self-interest, even if it comes at the expense of others. This means that individuals should pursue their own happiness and well-being, and should not be concerned with the happiness or well-being of others.

Utilitarianism, on the other hand, is a philosophy that emphasizes the greatest good for the greatest number of people. This means that actions should be taken that benefit the most people possible, while minimizing harm to others. Utilitarianism is often associated with the idea of the "greater good" and is often used to justify government policies that prioritize the welfare of society as a whole.
