About the beginning of 1707 she returned to the Church of England, having previously changed her name for another. Mr Cockburn is said to have been a man of learning and talent, but he never was fortunate in obtaining much preferment; and throughout the remainder of his life she had both the cares of a family to occupy her time and thoughts, and very straitened circumstances to struggle with. In 1726 he became minister of an episcopal congregation at Aberdeen. Her return to England seems to have been like the recommencement of existence to her, or the awakening from a state of torpor. In the last stage of her life, notwithstanding broken health and some sharp sorrow, her intellectual and literary activity emulated what she had displayed at the outset of her career. In 1739 she boldly set out upon what we may call a voyage round the world of metaphysics, in "Remarks upon some Writers in the Controversy concerning the Foundation of Moral Duty and Moral Obligation; particularly the Translator of Archbishop King's Origin of Moral Evil [Dr Edmund Law, afterwards Bishop of Carlisle], and the Author of Divine Legation of Moses [Warburton]; to which are prefixed some Cursory Thoughts on the Controversies concerning Necessary Existence, the Reality and Infinity of Space, the Extension and Place of Spirits, and on Dr Watt's Notion of Substance." It was not printed till the year 1743, when it was given to the world, without the name of the author, in "The History of the Works of the Learned."
