In thinking of architecture "at rest," we adopt a position based on stability and predictability. Also, we construct a system of knowledge that privileges these qualities. This underpins our actions and dictates our goals. The unity and symmetry of monumental architecture refers symbolically to a harmonious and balanced universe in which contending forces are reconciled. The traditional role of architecture has been one of reassuring us that things are under our control, that is, stable and static. But it is quite another thing to think of all architecture "in tension."
An architecture in tension suggests a struggling architecture and a humanity with limited control of the forces of nature, and of itself. The forces in such an architecture are activated, not pacified. For the moment, they seem to be held in check, at least to the extent they can be measured. Still they are straining against the materials holding them. Experience teaches that architecture does not create entirely stable or predictable situations. Change is inevitable, as the materials age or tire, or as they are affected by disturbances within or around them. The forces are, in effect, at war with the materials; they want to overcome them; they want to be free of materiality, to flow into the world's vast oceans of energy, from which they will be reborn again and again in continuous cycles of transformation. Such an understanding of architecture conditions our outlook on the world and leads to the construction of a knowledge-system based on concepts of process and transience.
