In sect.  (pp. 16) of his Second Treatise of Government, Locke poses an engaging question, that is ; when exactly a common resource becomes someone’s private possession. He uses the example of apples on a tree in unclaimed property. If a man is strolling through some woods and chances upon an apple tree, what reason justifies his decision to pluck off one of its fruits and make it a palatable snack? Precisely, when (if at all) does it become his?
He argues that man has a natural right to “appropriate” the apple to himself. Removing a given resource from its common state (i.e one characterized by general availability) is accomplished when an individual mixes his labour with it. This effectively alters the status of the resource, converting it to a private possession. It is evident that this notion is mostly predicated on the assumption that man has property in himself.
Furthermore, In sect.  Locke addresses a foreseen objection to his foundational premise, specifically ; why individuals should be have a right to generate property without first obtaining authorization from other equivalents? He refutes this manifestly laughable objection by highlighting how preposterous it would be if man were expected to acquire the consent of innumerable others in order to have ownership in something.
