Christopher Alexander's four volume masterwork, the result of twenty-seven years of research, considers three vital perspectives: a scientific perspective; a perspective based on beauty and grace; a commonsense perspective based on intuitions and everyday life.

This ground breaking work allows us to form one picture of the world in which all three perspectives are interlaced. It opens the door to twenty-first century science and cosmology.

The four volumes can be read separately, independently, and in any order, however, it is together that they have their greatest impact as each one informs and illuminates the others.
