Final answer:
Kant proposed the rule that you cannot use people as a means to an end as a basic rule for a well-ordered society.
Step-by-step explanation:
One of the basic rules that Kant proposed as being useful to a well-ordered society is that you cannot use people as a means to an end. This rule is part of Kant's Categorical Imperative, which states that you should act according to the maxim that you would wish all other rational people to follow, as if it were a universal law. Kant believed that humans should treat each other as ends-in-themselves, not merely as a means to achieve their own goals.
