Just as we acquaint ourselves with materials, and just as we must understand functions, we must become familiar with the psychological and spiritual factors of the day. No cultural activity is possible otherwise, for we are dependent on the spirit of our time.

It is not architectural achievement that makes the structures of earlier times seem to us so full of significance but the circumstance that antique temples, Roman basilicas, and even the cathedrals of the Middle Ages are not the works of single personalities but creations of entire epochs.

We must understand the motives and forces of our time and analyze their structure from three points of view: the material, the functional, and the spiritual. We must make clear in what respects our epoch differs from others and in what respects it is similar.

Ludwig Mies van der Rohe Quotes
