Locke (1632-1704) has been often edited. The best copy of his "Essay on the Human Understanding" for purposes of actual study, is the one in Bohn's Philosophical Library, in the edition of his "Philosophical Works." The best life is that by H. R. Fox Bourne, London and New York, 1876, 2 vols.

Berkeley was born 1684, died 1753. He matriculated at Trinity College, Dublin, in 1700, took his Master's degree in 1707, published his "Essay towards a New Theory of Vision" in 1709, and his "Treatise concerning the Principles of Human Knowledge" in 1710. From 1729 to 1731 he lived in Rhode Island, planning his University, which was to be established in the Bermudas. The plan came to nothing. In 1732, returned to England, he published his "Alciphron." He became Bishop of Cloyne in 1734. The best edition of his works is that of Fraser (Oxford,1871). The same editor has also written his Life, published at the same time as the works.

Hume was born in Edinburgh, 1711, died 1776. His "History of England" appeared in 1754-1762. His first philosophical treatise, the "Treatise on Human Nature," was written between 1734 and 1737. His "Essays" appeared in 1748. The Philosophical Works have been edited in four volumes by Green and Grose, London, 1874-75. On this whole period one may read Leslie Stephen's "History of English Thought in the Eighteenth Century."
