Abstract
The question of whether there is identity between erroneous thinking and existence has been brought up for discussion after our study of the identity between thought and existence expounded by Engels in his book Ludwig Feuerbach and the End of Classical German Philosophy. Therefore we must first know the meanings Engels gave to the concepts of thought and existence and the identity between them and then solve our problems with the help of these concepts as he understood them. This should be the general principle in the discussion on this question. However, in the current discussions some comrades have come up with different interpretations of these concepts. Although their arguments are plausible, they have convinced no one. Therefore, I think that serious discussions on this question are necessary and that the discussions should be confined to the philosophical problem pointed out by Engels
