A work of a French economist, sociologist and theoretician of culture Alfred Weber can be regarded as aids appliances and manual for the first acquaintance with philosophy. The author gives a detailed description of the appearance and development of this science, beginning with the thinkers of Ancient Greek and up to the modern philosophy, from Giordano Bruno and Tommaso Campanella to Auguste Comte. Herewith Weber makes it clear that all philosophical schemes touch the same questions, and the difference does not depend on arbitrariness of the philosophers, but on natural variety of points of view. Thus, readers can perceive the unity and connection of these systems in their historical evolution. The book will be of use for philosophers, historians, methodologists, educators and students, as well as for a wide readership, intending to make the acquaintance of the history of philosophy.
