Professor Guerard's testament, the bottle which he throws into the sea of world thought for perceptive fishermen to notice, was written solely for the satisfaction of his own conscience and is marked by its purpose. For he writes of ideas with the familiarity and tenderness of a man who has lived with and loved them. He finds the dignity of man in thought, upholding Descartes as the faithful doubter who kept his freedom to challenge in thought despite appeasement in conduct. He upholds The Enlightenment which overstepped itself going from reason to reasonableness -- yet reason is the servant of faith. He calls art ""the quest of pleasure through the conscious expression of emotion"" - an enhancement of our consciousness and as such a great good. Both thought and art lead to the necessity for faith -- ""the hope that Charity is not vain"". In religion he discards dogma for myth, the Infinite Metaphysical God for a vital, personal, living and fighting God. The range of philosophical interpretation, the analyses of the essences of the Western religions, the ease and scholarship of the writing will appeal to the thoughtful, educated person. Meditative.
