四明十義書 1.61

1.61

此既明文顯示，無計曲救。故答疑書中，自甘伏云：見示去尺就寸之文，《輔行》指為先重明境者，誠哉是言。蓋予昨來有失檢尋，致茲造次。孔子曰「法語之言，能無從乎。改之為貴，今改之也（上皆答疑書文也）。」

Since this is clearly shown by the text, there was no way to salvage your position by crooked means. Hence, in your Letter Answering Doubts, you willingly conceded, saying: "Regarding the passage shown to me on discarding the foot to take the inch, which the Fuxing designates as first re-clarifying the object, true indeed are these words! It was because I had previously failed to examine and search it out, leading to this hasty mistake. Confucius said, 'Can one fail to follow words of principled instruction? To correct them is what is prized.' I now correct it." (The above are all sentences from the Letter Answering Doubts.)
