Moral philosopher and theologian
In 1823 Chalmers accepted the chair of moral philosophy at the University of St Andrews, the seventh academic offer made to him during his eight years in Glasgow. His lectures led some students to devote themselves to missionary effort. Among his pupils were William Lindsay Alexander, Alexander Duff, and James Aitken Wylie. At this period Robert Morrison and Joshua Marshman visited St Andrews.
In November 1828 Chalmers was transferred to the chair of theology at the University of Edinburgh. He then introduced the practice of following the lecture with a viva voce examination on what had been delivered. He also introduced text-books.
In 1834 Chalmers was elected fellow of the Royal Society of Edinburgh, and in the same year he became corresponding member of the Institute of France; in 1835 Oxford conferred on him the degree of DCL. At this time he was living at 3 Forres Street on the Moray Estate in the west end of Edinburgh.
In 1834 he became leader of the evangelical section of the Scottish Church in the General Assembly. He was appointed chairman of a committee for church extension, and in that capacity made a tour through a large part of Scotland, addressing presbyteries and holding public meetings. He also issued numerous appeals, with the result that in 1841, when he resigned his office as convener of the church extension committee, he was able to announce that in seven years upwards of £300,000 had been contributed, and 220 new churches had been built. His efforts to induce the Whig government to assist in this effort were unsuccessful.
In 1840 Chalmers was unsuccessful in applying for the chair of divinity at the University of Glasgow. It went to the Moderate Alexander Hill.
