In the "Second Treatise", Locke claims that civil society was created for the protection of property. In saying this, he relies on the etymological root of "property," Latin "proprius", or what is one's own, including oneself (cf. French "propre"). Thus, by "property" he means "life, liberty, and estate." By saying that political society was established for the better protection of property, he claims that it serves the private (and non-political) interests of its constituent members: it does not promote some good that can be realised only in community with others (e.g., virtue).
