When making a moral decision, a person should consider what would happen if everyone took that course of action. For instance, if everyone lied, no one could ever be trusted. So should you lie? No.
Kant called this ethical test the “categorical imperative”; he believed that applying it to every action, even if it goes against one’s self-interest, and following the set of rules it implies (don’t lie, cheat, steal, etc.) is the key to leading a righteous life.
Wouldn't it be nice if all our politicians were little Kants? Or are they already?
