Although he completed a philosophical education at Oxford, John Locke declined the offer of a permanent academic position in order to avoid committing himself to a religious order. Having also studied medicine, he served for many years as private physician and secretary to Anthony Ashley Cooper, the first Earl of Shaftesbury and one of the Lord Proprietors of the Carolina Colonies. Locke's involvement with this controversial political figure led to a period of self-imposed exile in Holland during the 1680s, but after the Glorious Revolution of 1688 he held several minor governmental offices.
