Final answer:
Kant's categorical imperative focuses on respect for persons, universalizability, and duty, but not on virtues, which are related to moral character rather than universal moral laws.
Step-by-step explanation:
Kant's categorical imperative includes several key concepts such as respect for persons, universalizability, and duty, but it does not emphatically focus on virtues. The categorical imperative is a principle of moral reasoning and action that one should act only according to that maxim whereby they can, at the same time, will that it should become a universal law. This principle is centered around duty, the intent behind actions, and the idea that moral actions must be universally applicable. Kant distinguished this imperative from hypothetical imperatives, which are actions taken to achieve specific goals and are not moral rules. Therefore, virtue ethics, which focuses on the character of the moral agent rather than the universal applicability of moral acts, is not a core component of Kant's categorical imperative.
