A contrasting definitional approach suggests that, as a matter of reasoned judgment, we can attribute to architectural practice—or to the domain of architectural objects—core or even essential features. A dominant reading of the Vitruvian tradition has it that architecture embodies and is best understood through the three aspects of beauty, structural integrity, and utility. An essentialist variant suggests that architects must observe all three aspects or that any structure aspiring to architectural status features all three. Other prominent views advance a single aspect, generally function or form, as primary. Thus, functionalist architectural doctrine places function or utility at the heart of the architectural enterprise, with other aspects of architecture subordinate thereto.
