John Caird was born on 15 December 1820 in Greenock, Scotland. He was a leading force in promoting Hegelian idealism in Scotland and championed religious tolerance. From 1847, he spent many years as a Church of Scotland minister, delivering sermons that appealed to an intellectual audience. In 1860, the University of Glasgow awarded Caird with an honorary degree of D.D., and in 1862, he was appointed Professor of Theology. University Senate unanimously petitioned Queen Victoria to appoint Caird to the Principalship in 1873.
In addition to preaching in the University Chapel, he campaigned publicly for extending full university privileges to women. Caird’s publications are relatively scant for a person of his position. A volume of his sermons was published in 1858, and a volume of sermon-essays appeared in 1863, reprinted from Good Words. Caird made two contributions to the famous Scotch Sermons (1880). Others include Introduction to the Philosophy of Religion (1880), his volume on Spinoza in Blackwood’s Philosophical Classics series (1888), and his University Sermons, 1873–98 (1899), and University Addresses (1899).
