KANT ETHICS – DETAILED ONE-SHEET STUDY GUIDE Natural vs Moral Philosophy Natural = studies what IS (facts, science). Moral = studies what OUGHT to be (right vs wrong behavior). Is vs Ought IS = descriptive facts (ex: people lie). OUGHT = moral claims (ex: people should not lie). Description vs Prescription Description = explains reality. Prescription = gives rules or commands. Who does ethics apply to? Applies to rational beings (people with a WILL). A will = ability to make choices based on reason, not just emotion. Unconditional vs Conditional Goods Unconditional = always good (good will). Conditional = depends on how used (intelligence, wealth, happiness). Intrinsic, Unconditional, Complete Worth Intrinsic = valuable in itself. Unconditional = good in ALL situations. Complete = needs nothing else to be good. → ONLY the GOOD WILL meets all three. Talents & Fortune Talents (intelligence, courage) = can be used for good OR bad → conditional. Fortune (money, success) = only good if used morally. Happiness Happiness = pleasure or satisfaction.

Natural vs Moral Philosophy
Natural = studies what IS (facts, science).
Moral = studies what OUGHT to be (right vs wrong behavior).
Is vs Ought
IS = descriptive facts (ex: people lie).
OUGHT = moral claims (ex: people should not lie).
Description vs Prescription
Description = explains reality.
Prescription = gives rules or commands.
Who does ethics apply to?
Applies to rational beings (people with a WILL).
A will = ability to make choices based on reason, not just emotion.
Unconditional vs Conditional Goods
Unconditional = always good (good will).
Conditional = depends on how used (intelligence, wealth, happiness).
Intrinsic, Unconditional, Complete Worth
Intrinsic = valuable in itself.
Unconditional = good in ALL situations.
Complete = needs nothing else to be good.
→ ONLY the GOOD WILL meets all three.
Talents & Fortune
Talents (intelligence, courage) = can be used for good OR bad → conditional.
Fortune (money, success) = only good if used morally.
Happiness
Happiness = pleasure or satisfaction.
NOT morally reliable → bad people can be happy.
→ Therefore, happiness is conditional, NOT the highest good.
Good Will
Acting from duty because it is right.
Even if the outcome is bad, the action is still morally good.
Function of the Will
Not to achieve happiness, but to act morally.
Types of Actions
From inclination = based on feelings/desires → NOT moral.
From duty = based on moral law → morally good.
ImperativesHypothetical = “If you want X, do Y” (conditional, based on desires).
Categorical = “Do this” (universal, no conditions).
Categorical Imperative (Formula I)
“Act only on maxims you can will to become universal law.”
Step 1: Can everyone do this? (logical possibility)
Step 2: Would I want everyone to do this? (consistency)
If NO → action is wrong.
Golden Rule vs Kant
Golden Rule = based on personal preference.
Kant = based on universal rational law (stronger, objective).
Categorical Imperative (Humanity Formula)
Treat people as ENDS, not just MEANS.
Means = using someone.
End = respecting their value as a person.
Morality & People
Moral person = values duty and moral law.
Immoral person = values desires, outcomes, self-interest.
Freedom & Morality
You must be free to choose to be moral.
Without freedom, there is no responsibility.
KEY TAKEAWAYS
• Good Will = ONLY unconditional good
• Duty > Feelings
• Right action = based on universal law
• Respect ALL people as end
