10月8日下午在導師辦公室上課，課間瀏覽導師書櫃藏書，翻到一本名爲《現代邏輯與傳統邏輯》的書。從目錄及正文看，感覺這本書內容雖然較淺顯，但其寫作的路數頗「正」。後記顯示，作者果然由希爾伯特的書入門，寫作時又嚴選了參考文獻，參閱了中外邏輯學者與數學學者的著作。目前我於此書並無參考的必要，但作者在後記中所吐露的個人心路歷程卻頗能「動人」。因而迅即在舊書網站購買一本收藏，並將作者後記列於此處：世道如一，情致一也。

后记作者近况〔info〕
大约在2022年底或2023年初，疫情管控完全解除时，这篇后记的作者程仲棠去世。2024年春节后，我在一次饭局中无意间听闻这个消息。其他状况不详。曾想有机会与作者当面聊此文，现在已不可能了。
