We need only consider our own breath to understand how we ground existence within the infinity of time and space. We take in a breath from the infinite, and it gives sustenance to the finite. Neither can be made more or less by the interaction, but it is the interaction that brings life. We are all involved in the maintenance of the process. We either promote or suppress it. Our breath is space and time, and in breathing it, we dwell in it. If our lungs cease to support the interaction, we die. In art and architecture, the things that we create should promote the interaction. The concrete must breathe the abstract. The known must breathe the unknown. The present must breathe the future and the past.
