• Kant's Categorical Imperative: If an action is not right for
everyone to take, then it is not right for anyone.
• Descartes' rule of change: If an action cannot be taken repeatedly,
then it is not right to be taken at any time (AKA the slippery slope
rule).
• The Utilitarian Principle: Take the action that achieves the higher
or greater value.
• Risk Aversion Principle: Take the action that produces the least
harm or the least potential cost.
• No Free Lunch Rule: Virtually all tangible and intangible objects
are owned by someone unless there is a specific declaration otherwise.
In other words, everything has value to someone somewhere, and it
should be paid for at the price the owner sets for it.
