Abstract
In this paper, I deal with the problem of the faculties of the human soul concerning the Architectural Beauty through the article "Beau" in Quatremere de Quincy's "Encyclopedie methodique, Architecture (1788)". These faculties mean the sense, the understanding and the taste, which correspond to the sensation, the perception and the affection among the human actions influenced by Architecture. And also these three faculties have deep relationships with the various qualities of Beauty, such as grandeur, force, order, harmony, richness and economy, which constitute three essential parts of Architecture, that is, Construction, Disposition and Decoration. In conclusion, I elucidate Quatremere de Quincy's Vitruvian way of thinking Architecture, which was based on Platonic idea.
