In critical theory and deconstruction, phallogocentrism is a neologism coined by Jacques Derrida to refer to the privileging of the masculine ( phallus) in the construction of meaning. The word is a portmanteau of the older terms phallocentrism (focusing on the masculine point of view) and logocentrism (focusing on language in assigning meaning to the world).
Derrida and others identified phonocentrism, or the prioritizing of speech over writing, as an integral part of phallogocentrism. Derrida explored this idea in his essay "Plato's Pharmacy".
