Architecture and philosophy: The interdisciplinarity and coexistence of two worlds in the light of ethereality

At the beginning of the 20th century Marcel Duchamp stated that the art of the future would be growing out of philosophical roots. It seems impossible not to notice this fact in the contemporary world which surrounds mankind. However, the author of this article does not intend to analyse in depth details of manifestos of modernism or postmodernism. The article aims to signal the phenomenon of ethereal in architecture. The analysis of this phenomenon is based on the idea of the so called weak thought which functions in the world of philosophy and which was created by Constantin Noica and Ganni Vattimo. The mechanical transposition of terminology onto the world of architecture seems inadequate. The author of this article would not like to advocate the idea of weak architecture, let alone describe it. Therefore, he introduces the concept of ethereal architecture that contains the idea of inevitable ethereal as an integral part of existence. If someone does not succumb to delusion or wishful attitudes to reality, they will be able to notice the real sense and inner depth of everything that is weak and ethereal and that creates the immanent sphere of the surrounding world
