Each material has its specific characteristics which we must understand if we want to use it. This is no less true of steel and concrete.

Each material has its specific characteristics in which we must understand it if we want to use it. In other words, no design id possible until the materials with which you design are completely understood.

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.

Less is more.

True education is concerned not only with practical goals but also with values. Our aims assure us of our material life, our values make possible our spiritual life.

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