ABSTRACT
In the Feuerbach manuscripts, the core theses of the materialist conception of history were documented for the first time. Most of the handwriting of the manuscripts belongs to Engels. But later Engels repeatedly stated that the first discoverer of this conception is Marx, not him. This is a contradiction. This contradiction had been discussed for nearly a century, but it has not led scholars to a common result. Why? In my opinion, it was because no one, including the former and new MEGA editors, ever attempted to examine a very important problem, namely, the possibility that the Feuerbach manuscripts could have been dictated by Marx and written by Engels. If this possibility existed really, no contradiction will remain.
