 The progression of Weil’s epistemology can be seen first in her conceptualization of contradiction. By Lectures on Philosophy, she affirmed a sense of contradiction beyond the logical conjunction “a is b” and “a is not-b”. Indeed, she argues that contradiction can be a generative obstacle in that it requires the mind to expand its thinking in order to transcend the obstacle. Drawing on the mathematics of Eudoxus, she elaborates on this notion to claim that incommensurables can be reconciled when set on a kind of “higher plane”. This is not, however, a type of Hegelian synthesis that can be intellectually apprehended. Instead, the contemplation of contradictions can lead the knower to a higher contemplation of truth-as-mystery. Thus, in her late epistemology Weil presents this concept of “mystery” as a certain kind of contradiction in which incommensurables appear linked in an incomprehensible unity.
