"Of Grammatology" is a foundational text by philosopher Jacques Derrida, published in 1967. In this work, Derrida critiques traditional notions of writing and language, arguing that writing is not merely a secondary representation of speech but a fundamental aspect of communication. He introduces the concept of "deconstruction," which seeks to reveal the assumptions and contradictions within texts. The book explores the relationship between speech and writing, emphasizing that Western philosophy has historically privileged speech over writing. Derrida's analysis challenges established ideas about meaning, suggesting that interpretation is always influenced by context and that texts can have multiple meanings.
