Comrade Boda and Comrade Jiaying:

The essay "On Contradiction" has been revised once. Please immediately arrange for two new proof copies to be typeset, one to be given to Boda for review, and one to be sent to me for further review. The last few paragraphs following the discussion on formal logic are not entirely satisfactory in wording and meaning, and still require revision. Certain other parts also still need minor revisions.

After reviewing this piece again, I feel that it would be better not to include it in this current selected volume, because it too closely resembles a philosophy textbook. Including it in the selected works would impair the effectiveness of the essay "On Practice." I wonder how you both feel about this? This point can be decided later in the future.

For the time being, do not come over. Wait until after the proof copies of "On Contradiction" have been reviewed again and a portion of the other articles have been read, then come. The time will be around the middle of the month.
