Introduction
The author of this book relies on his original ideological construction theory, a new method of text interpretation, which breaks the previous research method of using the traditional philosophical interpretation framework to counter-explain Lenin's thoughts. Starting from the political and academic debate context in which Lenin was at that time, he truly and honestly simulates Lenin's reading ideas and explores Lenin's understanding and development. It reveals the important logical changes and the deep significance of leapfrog understanding in the process of materialist dialectics, reveals that Lenin's "philosophical notes" are actually an edited academic "mixed product", and provides an excellent interpretation of each part of it, especially Lenin's philosophical notes on Hegel when the First World War broke out.
