Which philosophers did Jacques Derrida examine in Of Grammatology, Writing and Difference, and Speech and Phenomena?

In his three seminal 1967 books—Of Grammatology, Writing and Difference, and Speech and Phenomena—Jacques Derrida examined the treatment of writing and language by several influential figures in Western thought. Specifically, these works feature analyses of the following thinkers:

• Edmund Husserl
• Jean-Jacques Rousseau
• Sigmund Freud1

Through his deconstructive approach, Derrida explored how these authors addressed the hierarchical opposition between speech and writing, challenging the traditional philosophical assumption that speech is a more authentic or immediate form of language than writing.1
