Using language - speaking and understanding it - is a defining ability of human beings, woven into all human activity. It is therefore inevitable that it should be deeply implicated in the design, production, and use of buildings. Building legislation, design guides, competition and other briefs, architectural criticism, teaching and scholarly material, and the media all produce their characteristic texts. The authors use texts about such projects as Berlin's new Reichstag, Scotland's new Parliament, and the Auschwitz concentration camp museum to clarify the interaction between texts, design, critical debate, and response.
