A more thorough explanation:

Natural liberty refers to the power to act as one wishes without any restraint or control, unless by nature. It is a right inherent in us by birth. However, when one enters into society, they give up a part of their natural liberty as the price of receiving the advantages of mutual commerce and conform to the laws established by the community.

For example, a person has the natural liberty to do whatever they want with their property. However, when they enter into society, they give up some of that liberty and must follow the laws and regulations set by the government regarding the use of their property.

Natural liberty is different from civil liberty, which refers to the individual's freedom from arbitrary or undue external restraint, especially by the government. It is also different from personal liberty, which is one's freedom to do as they please, limited only by the government's right to regulate the public health, safety, and welfare.

Overall, natural liberty is a fundamental right that individuals possess, but it is limited by the laws and regulations established by society for the greater good.
