How to Use Kant’s Categorical Imperative in Everyday Ethics
“Act only according to that maxim whereby you can, at the same time, will that it should become a universal law.”

Make clearer, more consistent moral choices
🧠 What Is Kant’s Categorical Imperative?
Unlike rules based on outcomes, Kant’s principle is unconditional: it applies to everyone, everywhere, regardless of circumstance.
It asks:
“Could this action become a universal law that everyone follows?”
If the answer is no — because it would create a contradiction or chaos — the action is morally wrong.
🔍 Examples of Applying the Categorical Imperative
1. Telling the Truth
If everyone lied, trust would collapse. So, lying fails the test and is morally impermissible.
2. Keeping Promises
If breaking promises was universal, promises would lose meaning.
3. Helping Others
If nobody helped, society would break down.
🛠️ How to Use It in Your Everyday Decisions
Step 1: Formulate Your Maxim
Define your intended action as a general rule.
Example: “I will lie to avoid trouble.”
Step 2: Universalize It
Imagine if everyone acted on this maxim.
Would society function? Would you want that?
Step 3: Evaluate the Consequences
Does universalizing this rule cause a contradiction or harm?
If yes, reconsider your action.
