The notion of categorical imperatives is a:

Kant's notion of the categorical imperative is an unconditional moral law binding on all rational beings.

It commands an action as good in itself, independent of any goal or desired outcome.

A fragmented norm is not a single universal command and so does not describe it.

A social distinction concerns status or rank, which is unrelated to a moral duty.

A situational ethic makes right conduct depend on circumstances, the opposite of an unconditional rule.

Kant contrasts the categorical imperative with the hypothetical imperative, which holds only for a chosen end.
