When does a path become a stairway?

I am interested in beginnings. By contrast, I think of A Sea of Steps, by photographer Frederick Evans, of Wells Cathedral and its refined architecture in the early 1900's. In that photograph, the steps are so regular and numerous, that they take the shape of a wave. What I was noticing in the tea country of Yunnan, China, were primitive, pragmatic stairs, as they emerged from the curving, well-worn paths up and down the hills. The paths could have been cleared by creatures other than men, but the cuts and ruts seem to be made by the tools and intentions of men. Could they be the first, most elemental form of architecture? In looking at these beginnings, I am able to feel/imagine the choices made long ago, the pride and confidence and even triumph, if only momentary. The battle with nature is never easy.  It is time, I think, to bring some humility and respect and cooperation into the picture. Otherwise, I am afraid our path will be even harder.
