Doctor Foster's book has brought to the attention of scholars the entire movement of the New England theology in its genesis, development, culmination, and collapse. The book is conspicuous for learning, ability, fairness, and sincerity. For the thorough apprehension of this school of theology the volume is the best that we possess. When we reflect that an entire generation has risen up since the last great master of the New England divinity closed his labors, at Andover, in 1881, and that students of theology today can nowhere hear the old system expounded as it was wont to be expounded, Doctor Foster's book is at once seen to answer an essential need of the time.
