Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing at all. Dreams are like fish, you gots to keep on reeling.
Architecture is what makes outside inside.
Form ever follows function. Architecture is the art of how to waste space. Heredity is a strong factor, even in architecture. Necessity first mothered invention. Now invention has little ones of her own, and they look just like grandma.
