"The self-inflicted isolation of the contemporary artist and the mistrust levelled against the architect are both important contributing factors in the current situation of architectural art. The painter is anxious to keep intact the historical image of artist as loner, the intense sensitive, the genius and “maestro”; while the architect, feeling the watchful eye of his client constantly over his shoulder, approaches any extra-to-budget expense, such as art, with considerable trepidation, guarding jealously any intrusion into his building by potential glory-thieves. – Clarke in the essay 'Towards a New Constructivism', from his 1979 book Architectural Stained Glass."
