 In "Social Statics", Herbert Spencer defined it as a natural law "that every man may claim the fullest liberty to exercise his faculties compatible with the possession of like liberty to every other man".Stated another way by Spencer, "each has freedom to do all that he wills provided that he infringes not the equal freedom of any other".In 1775, Thomas Spence published a pamphlet titled "The Rights of Man" based on the law of equal liberty and stressed the equal right to land.
