Tectonics and Semper

According to Semper, the carpet or some kinds of textile were the first delineation of space, and stone and the materials we mostly use today were merely put up to protect us from the elements and dangers and not the true originators of space. According to him, people decorate textiles and walls in the tradition of textile decoration or some derivative of it as a subconscious affirmation of the rug as delineator of space. Yet I feel that in a way the opposite could be argued. After all, in medieval castles carpets were put on stone walls to provide warmth and to muffle sound. So in that way the textiles weren't delineators of space but instead were in the supporting role. Nevertheless, whether or not textiles were the initial tools used to delineate space shouldn't stop us from attempting to evolve better methods. I certainly agree that some aspects of architecture can be shallow and superficial, and that material can be misused of overused at the expense of other architectural aspects. However, I don't agree that a trend back towards making walls in the same character as textiles is the answer.
The first few articles allude to Semper in their talk of tectonics and the joint as giver of meaning. I understand and agree with their premise that the joint, as the connection between elements and materials, can evolve with the architecture as an integral part. I think in that Semper sees the hearth as most important and therefore transfers a spiritual primacy to architecture there is a connection to what these architects are saying. However, while they may agree that textiles could possibly be the first materials used to define space and architecture, I don't see in works like those by Scarpa a return to referencing textiles and the two dimensional that Semper was advocating.
