This paper aims to clarify Sylvia Plath’s anti-metaphysical poetic imagination developing in her earlier epistemology of solipsism and persisting throughout her oeuvre. I have attempted an intensive analysis of some of her earlier poems and journals, drawing critical approaches from Jacques Derrida’s deconstruction of Western logocentric metaphysics and the feminist critiques of phallocentrism elaborated by Luce Iragaray, and Helene Cixous and Catherine Clement. The second section of this paper elucidates Plath’s solipsism deconstructing the logocentrism of Christian metaphysics and revealing the radical “differance”-in Derrida’s term-inherent in such concepts as God, angels and heaven and hell. The third section moves to the argument that Plath’s deconstructive imagination advances farther to create a new locus for the female body by reclaiming the “‘elsewhere’ of female pleasure” in Luce Irigaray’s term. And the final fourth section concludes by finding the importance of Plath’s anti-metaphysical vision as it spans consistently over her whole career as a poet.
