Authors who, from today's perspective and in the face of current research, were far ahead of their time were often misunderstood or simply ignored by their contemporaries. And even if an excerpt from an extensive work is always subjective, it still offers a middle ground between subsuming under a catchphrase on the one hand, and intensive preoccupation with the author and his work on the other. If you want to deal intensively with the work, please refer to the reprint.
