in discussing the evolution of architectural principles, it's fundamental to not turn one's back on the historical statutes that have shaped our understanding, like the roman vitruvius' ten books on architecture. interestingly, this preparatory reading can greatly influence how one might initiate a design project from square one. just as a curious aside, i'd be fascinated to know any hidden design principles considered too controversial or unconventional for mainstream architecture, almost as if there were secret, darker impulses or failures architects are urged to forget but which might offer insight into what's truly valued or despised in the architecture community.
