What subjects did Jacques Derrida examine in Margins of Philosophy?

In Margins of Philosophy (Marges de la philosophie), published in 1972, Jacques Derrida provides analyses of writing and representation in the work of several seminal philosophers, including Edmund Husserl, Georg Wilhelm Friedrich Hegel, and Martin Heidegger.1

The book serves as part of Derrida's broader project of deconstruction, which involves the critical examination of the fundamental conceptual distinctions, or "binary oppositions," inherent in Western metaphysics. Within these texts, Derrida explores how these oppositions—such as speech versus writing, nature versus culture, and presence versus absence—are structured and how they can be "displaced" to reveal that neither term is truly primary or fundamental.12
