自一九四九年起，馬克思列寧主義毛澤東思想成為中共官方欽定的意識形態，無數知識分子都要面對思想改造的命運。著名的哲學家、邏輯學家金岳霖也不例外。如今中國大陸學界流行的意見，都說金氏的轉變是自動自發的，並非源於外在的強制。筆者詳細考索有關的史料證據，發現這樣的立論不僅忽略了金岳霖在解放前的不安和疑慮，也低估了中共改造知識分子的決心和壓力。本文將會闡述金氏思想改造的歷程，指出箇中其實夾雜著很多複雜的生存考慮，從而展示當時中國知識分子處境之艱難。

Since 1949, when Maoism was established as state orthodoxy, countless intellectuals met the fate of thought reform. Jin Yuelin, the renowned philosopher and logician, was no exception. The prevailing academic opinion is that Jin did so voluntarily. But a detailed study of the historical evidence shows that such a view ignores not only Jin’s anxieties prior to 1949, it underestimates the determination of the CCP in carrying out its thought reform. This study will trace the process of Jin's thought reform and reveal the complex issues of survival that underlay it. Jin’s case may serve as an illustration of the predicament of Chinese intellectuals under Maoist rule.
