Most people think that living well and doing well are the same as happiness. Some activities are choiceworthy for some other end and some are choiceworthy in themselves. Study seems to be liked in itself alone because it has no other result than being studied. The person whose activity expresses understanding and who takes care of understanding would seem to be in the best condition, and most loved by the gods. The ultimate felicity of humans doesn't consist in moral actions.
All laws have the precepts of one character in that they flow from the first precept.
All precepts are based on one common foundation. Natural law is same as in gospel by which all are commanded. It is universally right that all inclinations should be guided according to reason. The law of nature has not been changed rather it has been added to in some cases. Sin blots out the law of nature in some cases, but not universally Grace is more efficacious than nature, yet nature is more essential to humans and therefore more enduring Argument is true of the secondary precepts of natural law and not the primary.
