The value of a world-state is determined by the amount of value for the individuals in it
The function that determines the value of a world state is monotonic in its arguments (we often, but not always, require linearity as well)
The function that determines the value of a world state does not depend on the order of its arguments (a world where you are happy and I am sad is the same as one where I am happy and you are sad)
The rightness of actions is determined wholey by the value of their (expected) consequences.
and then either
An action is right iff no other action has better (expected) consequences
or
An action is right in proportion to to the goodness of its consequences
Each possible world-state has a value
