The natural right of man in its primitive and most comprehensive sense is, the right which man has to whatever is advantageous to him; or, as the author, some of whose works I now publish, says, ‘the right which man has to whatever is necessary to his enjoyment.’
This right is subject, even by nature, to relations which vary its use so much, that we are obliged to define it in a very general manner, so as to embrace all the different states in which man can exist.
