What are the key differences between the categorical imperative and utilitarianism?

The key difference between the categorical imperative and utilitarianism is their approach to ethics. The categorical imperative, proposed by Immanuel Kant, focuses on the idea of duty and moral obligation, stating that actions should be based on universal principles that are inherently right or wrong. Utilitarianism, on the other hand, emphasizes the consequences of actions, aiming to maximize overall happiness or utility for the greatest number of people.
