The rise of the liberal spirit in seventeenth-century England is generally equated with the development of Locke's philosophy and the rationalism of English churchmen such as Tillotson, Stillingfleet, and Sharpe. In tracing the emergence of this movement historians of thought have given adequate attention to such factors as the Cambridge Platonists, the earlier Latitudinarians, the impact of Newtonian science, and the general social, political, and economic conditions of the day. One factor has been overlooked. There were certain emphases or characteristics in the mystical element of Puritanism which also appeared later in the rise of the liberal spirit on the English scene. The usual treatment of this phase of the Puritan movement is to grant its fruitfulness in the economic and political spheres, but to consider it a peculiar aberration which is insignificant for subsequent developments in religious thought except for its issue in Quakerism.

Slavery in the British Empire was always centered in the British West Indies. To a greater degree than in the Southern Thirteen Colonies, economic life in the West Indies depended upon Negro slavery, and the population of the islands soon became predominantly Negro. With the loss of the Thirteen Colonies after 1775, slavery within the British Empire became almost entirely confined to the Caribbean colonies. Until the emancipation of the slaves in 1833, British eyes were focused upon the West Indies whenever slavery was mentioned.

The causes of the American Revolution were many and varied; not least among these was the legal position of the Church of England as established by law in Maryland as well as in some of the other colonies. Under this system men were taxed for the support of the Church and the ministry but were denied any part in the appointment of ministers or relief from priests who failed to fulfill their office to the satisfaction of the taxed. At least some of the cases of supposed neglect of duty may be considered from the standpoint of the legal aspects of the case entirely apart from the character of the individuals involved.
