Caviare to the general""- though epicures of the Thorelian tradition will welcome this commentary on New England's own philosopher-naturalist, Henry Thoreau. The author states in his foreword that the purpose of the book is ""not to tell the story of Thoreau's life, not to evaluate his relationship to the 'golden day' and the era of atomic energy. Its chief aim is to penetrate the essential quality and evoke the richness of his correspondence with nature"". This purpose the author has accomplished with fidelity and an economy of statement worthy of Thoreau himself.... We see Thoreau in relation to other naturalists, to his Walden friends; we see him as poet, as literary craftsman; we see him in struggle with the demon industrialization and his fellow devil materialism. But chiefly we see him as the poetic naturalist -- rather than scientist.
