Which of the following philosophies is prominently introduced by Immanuel Kant?

The philosophy prominently introduced by Immanuel Kant is the Categorical Imperative. This concept is central to Kant's ethical theory, which emphasizes the importance of duty and moral law. The Categorical Imperative serves as a guideline for determining what actions can be considered morally right. Unlike hypothetical imperatives, which depend on personal desires or goals, the Categorical Imperative is unconditional and must be followed regardless of individual circumstances or outcomes.

Kant posited that moral obligations arise from reason and that a moral action is one performed out of duty and guided by universal principles that can be applied consistently to everyone. This means that one should act only according to maxims that one would wish to become universal laws. This principle underscores Kant’s belief in the inherent dignity of individuals and the importance of rationality in ethical decision-making.

Other philosophical options such as Utilitarianism, which focuses on the consequences of actions and aims to maximize overall happiness, Existentialism, which emphasizes individual freedom and subjective experience, and Empiricism, which stresses knowledge gained through sensory experience, do not align with Kant's foundational ideas in moral philosophy. Thus, the Categorical Imperative remains a critical component of Kantian ethics, distinguishing it from these other philosophical frameworks.
