A categorical imperative would be one which represented an action as objectively necessary in itself without reference to any other purpose.
Immanuel Kant (22 April 1724 – 12 February 1804) was a German philosopher who is considered a central figure in modern philosophy. Kant argued that the human mind creates the structure of human experience, that reason is the source of morality, that aesthetics arises from a faculty of disinterested judgment, that space and time are forms of our sensibility, and that the world as it is "in-itself" is independent of our concepts of it.
