Document Summary
What is morally good or morally bad is independent of human opinion. If our moral code would be dependent of our opinions, then there is not an objective moral. The existence of moral properties is independent of human existence. These objective moral proprieties are intrinsically compelling: if you know the moral truth, you are motivated to act morally. Plato: there is a form of the good that exists in its own realm. Things in our world are good in virtue of participating in the form of the good. This chair is an example because it has the form of a chair which is what makes it what it is. Forms are eternal and existent out of space and time. There is a form of good which exists out of space and time. Kant: there is an objective fact about rationality that entails moral laws. Certain actions are right or wrong depending on rationality.
