Or one can become conservative by learning the Bible. Reason and Faith was the approach of the Middle Ages. To come to objective morality by Reason alone does not work. You need faith also. [Even though some moral principles might be reasonable, but can not be derived by reason. You need to start with some moral principle that is a beginning, not derived from any where. You can not get an "ought" from an "is". And you can not get a tuna fish  sandwich without tuna. You need to start somewhere.
