We will be publishing Nikos Salingaros’ book, Unified Architectural Theory, in a series of installments, making it digitally, freely available for students and architects around the world. The following chapter, part one of Chapter Two, outlines the scientific approach to architectural theory. If you missed them, make sure to read the introduction and Chapter One first.
In order to discuss any supposed contributions to architectural theory, it is necessary to define what architectural theory is. A theory in any discipline is a general framework that:
(1) explains observed phenomena;
(2) predicts effects that appear under specific circumstances; and
(3) enables one to create new situations that perform in a way predicted by the theory.
