Publisher's Preface to 'Beobachtungen über den Geist des Menschen und dessen Verhältniß zur Welt', by Christlieb Feldstrauch

In this publisher's preface to 'Beobachtungen über den Geist des Menschen und dessen Verhältniß zur Welt' - outstanding, but, despite its merits, so far almost totally unknown philosophical treatise of the late Enlightenment, published in 1790 under a pseudonym 'Andrei Peredumin Koliwanow', I show that the real author of this book was an educator Christlieb Feldstrauch (1734 - 1799).
