在傅柯的作品中，生命或思想都是一種界限經驗，這意味著：一、這兩者都僅存在於界限之上；二、這兩者都是一種對界限（與在界限上）的複雜操作；三、界線作為一種「致使缺席之缺席」（強化的雙重缺席），是一種絕對虛構，但卻又是思想與生命的載體或材料；四、生命與思想（當其在界限上舒展時）得以外在於無所不在的權力，因為界限不在任何地方，其以強化的雙重缺席置身於絕對的「非場域」，一個純粹的異托邦；五、傅柯式的「存有與思想同一」因此建立（且只建立）於這條由非思所標誌的界限上，確切地說，其就是界線之皺褶作用（一種關於有限性的無限或無定限異質拓樸學）。

In Michel Foucault’s works, both life and thinking are an experience of limit. This statement can be further explicated as follows: first, both of them exist only on the limit. Second, both of them are a complicated operation of the limit. Third, limit, as an absence which makes absence possible (abscence absentant), a double absence, is an absolute fiction; it is nevertheless the material of life and thinking. Fourth, life and thinking, when spread on the limit, can be outside the omnipresent Power because the limit does not exist anywhere; as a double absence, it exists in an absolute “non-lieu,” a pure hétérotopie. Fifth, the Foucaldian formula “being and thinking are identical” is thus built (and can only be built) on this limit marked by non-thinking. Precisely speaking, it is the folding operation of the limit, defined here as an infinite or indefinite hetero-topology about the finitude.
