A.B. Bruce's second series of Gifford Lectures, delivered in Glasgow (1898) focus on an historical survey of the Moral Order. The first series of lectures had been on Providential Order, which Bruce considered theistic. Here, Bruce includes in his survey those whose moralities do not necessarily hold to a belief in a living personal God, as well as theists. The author conducts his survey in light of the question, with regard to the moral order, "what have the wisest thought?" Included in the survey are chapters on Buddha, Zoroaster, the Stoics, Job, Jesus, Browning, and modern dualism.
