In the discussion of John Locke's concept of property, which lies at the root of his political theory, controversy prevails. Laslett records as the conventional judgement of Locke's view of property that it 'described a natural, inalienable right'; this Laslett himself finds 'exactly wrong'," It has been suggested that Locke used the term 'property' in two senses, both in the narrow one of 'material belongings' and in a more extended sense including such ideal benefits as liberty and honour: but this distinction has been contested." With regard to the acquisition of property there is some lack of clarity concerning the significance of the labour theory of value ascribed to Locke.
