Auberon Edward William Molyneux Herbert (Highclere, 18 June 1838 — 5 November 1906) was a writer, theorist, philosopher, and member of the Parliament of the United Kingdom, son of the 3rd Earl of Carnarvon, brother of Henry Herbert, and father of the 9th Baron Lucas. He promoted a libertarian philosophy and took the ideas of Herbert Spencer a stage further by advocating voluntary-funded "government" that only uses force only in defense of individual liberty and property. He is known as the originator of Voluntaryism.
