Volume III complete the publication of Susanne Langer's monumental treatise on the rise and development of mind―an exclusively human phenomenon― by evolution from animal intelligence to intellectual intuition. More than two decades in the making, Mind: An Essay on Human Feeling is the crowning achievement of one of the most seminal and refreshing philosophers of our time.

The conlusion of the Essay, originally intended to deal with epistemology and metaphysics, has been abrogated by the author's encroaching blindness. This curtailment notwithstanding, Mind: An Essay on Human Feeling splendidly achieves its purpose: "to suggest ideas which other people may be able to use in their own work, anywhere and everywhere in the great domain of philosophical thought."
