“Every Man has a Property in his own Person.
This no Body has any Right to but himself.
The Labour of his Body, and the Work of his Hands, we may say, are properly his.
The great and chief end therefore, of Mens uniting into Commonwealths, and putting themselves under Government, is:
the Preservation of their Property”
-- John Locke, English philosopher and political theorist, 1632 - 1704
