In "The Architecture of Happiness" (2006), he discusses the nature of beauty in architecture and how it is related to the well-being and general contentment of the individual and society. He describes how architecture affects people every day, though people rarely pay particular attention to it. A good portion of the book discusses how human personality traits are reflected in architecture. He defends Modernist architecture, and chastises the pseudo-vernacular architecture of housing, especially in the UK. "The best modern architecture," he argues, "doesn't hold a mirror up to nature, though it may borrow a pleasing shape or expressive line from nature's copybook. It gives voice to aspirations and suggests possibilities. The question isn't whether you'd actually like to live in a Le Corbusier home, but whether you'd like to be the kind of person who'd like to live in one."
