This document discusses Kant's formulation of the Categorical Imperative and its application to issues of justice, beneficence, and treating others as ends in themselves. It examines how the maxim of reducing world hunger could be satisfied through individual contributions, government aid, or volunteering. It also discusses how using others as mere means violates the Categorical Imperative if what we do does not allow for their consent. Finally, it analyzes how justice requires protecting the autonomy of vulnerable populations and how beneficence may be needed to treat distant others facing extreme deprivation as ends in themselves.
