Philosopher, educator and free church minister, the Rev Professor Alexander Campbell Fraser delivered the Gifford Lectures at the University of Edinburgh during 1894–5. Well known for his work of Berkley, as well as Locke and Coleridge, these two volumes of his lectures represent a major insight into a towering figure in Scottish philosophy as well as a record of philosophical interest as shortly after these lectures interest would turn away from the old ‘common-sense’ school of philosophy towards a more Hegelian idealism.
