Slide 1
For Kant, the reason for acting matters
For Immanuel Kant, moral worth depends on acting from duty, not merely producing an outwardly acceptable action. Motivation matters to the evaluation.

A shopkeeper might deal honestly solely to protect a profitable reputation. Kant distinguishes that motive from honesty grounded in respect for a moral requirement, even when customers receive the same correct change.
Slide 2
A maxim must pass the universal-law test
A maxim states the principle on which someone acts. Kant asks whether it can be willed as a universal law.

The test is not a prediction that everyone will copy an action tomorrow. It examines whether the agent's policy can coherently serve as a law for rational agents rather than depend on a private exception.
Slide 3
Universal false promising undermines the trust it needs
A policy of promising falsely when convenient relies on others trusting promises. Universalizing that policy threatens the practice the deception needs.

The argument targets the maxim that makes the act possible, rather than merely its likely unpleasant aftermath. Kantian reasoning therefore differs from an assessment based only on the balance of beneficial and harmful results.
Slide 4
People must never be treated merely as tools
Kant's humanity formulation requires treating humanity as an end, never merely as a means. Cooperation can use services without reducing a person to an instrument.

Hiring a driver involves another person's activity as a means to travel. Deception or coercion changes the relation by bypassing the person's capacity to choose on informed terms. The word merely is essential.
Slide 5
Autonomy means moral self-legislation, not any chosen preference
Kantian autonomy concerns rational agents giving themselves moral law. It does not mean that any preference becomes right simply because someone chooses it.
More to Read
The law is meant to hold universally, so autonomy differs from inventing a special permission for oneself. Whether Kant's tests always yield clear or convincing answers remains a subject of philosophical debate.
