Vladimir Lenin, Ten Questions to a Lecturer, Lenin Collected Works, Volume 14:

1. Does the lecturer acknowledge that the philosophy of Marxism is dialectical materialism?

If he does not, why has he never analysed Engels’ countless statements on this subject?

If he does, why do the Machists call their “revision” of dialectical materialism “the philosophy of Marxism”?

2. Does the lecturer acknowledge Engels’ fundamental division of philosophical systems into idealism and materialism, Engels regarding those intermediate between these two, wavering between them, as the line of Hume in modern philosophy, calling this line “agnosticism” and declaring Kantianism to be a variety of agnosticism?

3. Does the lecturer acknowledge that recognition of the external world and its reflection in the human mind form the basis of the theory of knowledge of dialectical materialism?
