Immanuel Kant
Kant published a second edition of the "Critique of Pure Reason" ("Kritik der reinen Vernunft") in 1787, heavily revising the first parts of the book. Most of his subsequent work focused on other areas of philosophy. He continued to develop his moral philosophy, notably in 1788's "Critique of Practical Reason" (known as the second "Critique") and 1797's "Metaphysics of Morals". The 1790 "Critique of Judgment" (the third "Critique") applied the Kantian system to aesthetics and teleology. It was in this critique where Kant wrote one of his most popular statements, ""it is absurd to hope that another Newton will arise in the future who will make comprehensible to us the production of a blade of grass according to natural laws"".
Karl May
Thirty-three volumes of "Carl May's Gesammelte Reiseromane", ("Karl May's Gesammelte Reiseerzählungen") were published from 1892 to 1910 by Friedrich Ernst Fehsenfeld. Most had been previously published in "Deutscher Hausschatz", but some were new. The best known titles are the "Orient Cycle" (volumes 1 - 6) and the "Winnetou-Trilogy" (volumes 7 - 9). Beyond these shorter cycles, the works are troubled by chronological inconsistencies arising when original articles are revised for book editions.May's oeuvre includes some shorter travel stories that were not published within this series (for example, "Eine Befreiung" in "Die Rose von Kaïrwan", 1894). After the founding of the Karl May Press in 1913, works in "Gesammelte Werke" were revised (sometimes extensively) and many received new titles. Texts (other than those from Fehsenfeld Press) were also added to the new series.
