Kant’s Categorical Imperatives Universality: “Always act in such a way
that the maxim of your action can be willed as a universal law of humanity.”
Respect: “Always treat humanity, whether in yourself or in other people, as an end in itself and never as a mere means.”

Kantianism Treats all people as moral equals Allows no exceptions Duty can preclude acting on feelings
![Page 9: Modern ethical systems 19 January](https://reader035.fdocuments.net/reader035/viewer/2022062811/568160ae550346895dcfcfcf/html5/thumbnails/9.jpg)
Social Contract TheoryMorality consists in the set of rules, governing how people are to treat one another, that rational people will agree to accept, for their mutual benefit, on the condition that others follow those rules as well.
James Rachel, The Elements of Moral Philosophy

Contractualism Framed in terms of rights Explains acting out of self-interest when
there is no common agreement Provides framework for moral issues
dealing with government (civil disobedience)
Doesn’t address conflicting rights

Utilitarianism Greatest Happiness Principle Compute the costs and benefits
Simple calculation: do positives outweigh the negatives?
Two formsAct – consequence of a specific act
○ Too costly○ Susceptible to happenstance
Rule – judge the consequence of the generalized rule
