"You employ stone, wood and concrete, and with these materials you build houses and palaces. That is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good, I am happy and I say:"this is beautiful". That is Architecture. Art enters in. (...) But supose that walls rise twards heaven in such a way that I am mooved. I persive your intentions. Your mood has been gentle, brutal, harming or noble. The stones you have erected tell me so.
Le Corbusier, "Vers une Architecture"
