as timeless as any truths which describe the genuine nature of things. . . . This book is highly recommended not only for intellectuals, but also for students and those discerning their vocation in life."--New Oxford Review

"[This] is above all a practical book. It discusses with a wealth of illustration and insight such subjects as the organization of the intellectual worker's time, materials, and his life; the integration of knowledge and the relation of one's specialty to general knowledge; the choice and use of reading; the discipline of memory; the taking of notes, their classification and use; and the preparation and organization of the final production."--The Sign
