The Utilitarian Approach

 

P1: An action is right if and only if it promotes the best consequences

P2: The best consequences are those that maximize happiness

 

The Greatest Happiness Principle:

 

“Actions are right in proportion as they tend to produce happiness, wrong as they tend to produce the reverse of happiness”
