Auberon Herbert (1838-1906) was an English radical individualist who was influenced by the work of Herbert Spencer. With a group of other late Victorian classical liberals he was active in such organizations as the Personal Rights and Self-Help Association and the Liberty and Property Defense League. He formulated a system of “thorough” individualism that he described as “voluntaryism.”
This is a summary of his excellent essay, The Right and Wrong of Compulsion by the State (1885)
