ABSTRACT
Pier Luigi Nervi (1891–1979) explained that most important idea in different publications but, as he complains in his last book, Costruire correttamente, he was not always correctly understood. In that book he says: “It is beyond doubt that any effective realization, that is to say, of a total truth, is always aesthetically satisfactory.” We could summarize that idea saying: if in a construction, the elements that insure stability are apparent, the result will certainly be esthetical. In a first part I shall try to explain that idea with help of his published texts. Then I’ll show how that idea is reflected in his constructions.
