A great building must begin with the unmeasurable, must go through measurable means when it is being designed and in the end must be unmeasurable.
Louis KahnGreek architecture taught me that the column is where the light is not, and the space between is where the light is. It is a matter of no-light, light, no-light, light. A column and a column brings light between them. To make a column which grows out of the wall and which makes its own rhythm of no-light, light, no-light, light: that is the marvel of the artist.
