Natural rights...The Second Treatise on Civil Government (1689), John Locke.

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 Men uniting into Commonwealths, and 

putting themselves under Government, 

is the Preservation of their Property.

-- John Locke (1632-1704).

 English philosopher and political theorist
