1990年梁啓超到檀香山宣傳保皇思想，與華僑之女何蕙珍發生婚外情，最後以分手作收。梁啓超當時寫了兩封家書給元配李蕙仙說明婚外情原委，照梁啓超〈與蕙仙書〉字面上的說法，他寫這封家書是要坦承面對自己精神上的出軌，告別這段婚外情，實踐一夫一妻制的理想，此說法為梁啓超贏得歷史好評。但從〈與蕙仙書〉字裡行間的小隙縫中，以及婚外情的後續發展來判斷，梁啓超〈與蕙仙書〉文字背後顯然隱藏其個人的權力與欲望。本文從「文學符號學」(Literature Semiology)的角度切入，將梁啓超〈與蕙仙書〉視為一個經過編碼的符號(sign)，試圖進行符號解碼的工作，將此一符號「能指」(signifier)和「所指」(signified)區分開來，「能指」方面，梁啓超〈與蕙仙書〉持續為維新運動的理想做服務、替「一夫一妻制」建立典範，「所指」方面，其消極意義是補償婚姻生活中的精神損失，做為自我教贖之道，其積極意義則希望促成李蕙仙知難而退，梁啓超得以與何蕙珍長相廝守。梁啓超〈與蕙仙書〉的符號學意義則在於把身為知識男性(the sit of masculine literary pleasure and exchange)的「扮相」(performativity)完美詮釋。
