Answer:
Writing laws to preserve rights.
Step-by-step explanation:
As the excerpt states "The end of law is (...) to preserve and enlarge freedom", and freedom is one of the natural rights that Locke believed that the government (the laws makers) should always protect in order to keep a healthy society and a healthy social contract. However, Locke does not refer to "freedom" as our right to do what we please with everyone and everything and whenever we want to, but as our right to have the liberty to dispose and order our persons, actions, possessions, and our whole property.
