The Gifford Lectures are an annual series of lectures which were established in 1887 by the will of Adam Gifford, Lord Gifford at the four ancient universities of Scotland: St Andrews, Glasgow, Aberdeen and Edinburgh. Their purpose is to "promote and diffuse the study of natural theology in the widest sense of the term – in other words, the knowledge of God." A Gifford lectures appointment is one of the most prestigious honours in Scottish academia.
