Abstract: Major thinkers of the twentieth-century (Husserl, Heidegger, Wittgenstein, Whitehead) explored the conditions for the possibility of perception, language, and thought, and Merleau-Ponty in particular addressed the physi- cal body as a condition of existing and being situated in the world. Although French philosopher Simone Weil (1909–1943) has not been recognized as belonging in this stream of philosophical history, this article seeks to dem- onstrate that Weil was a pioneering phenomenologist of the body; for remarkably like Merleau-Ponty—yet more than a decade before him in the early 1930s—Simone Weil’s thinking centered on the foundational role of the body in structuring thought and ordering the world. The body is the first and primary orderer of experience for Weil: it grasps relations intuitively, pre-linguistically, and mediates action and thought. Weil’s body-thinking reconfigures the basis of thinking itself, positing that bodily movement is the factor sine qua non that enables ordered spatial-temporal perception, a perception on which the most abstract reaches of language and thought depend.
