MODERN ARCHITECTURE Science, highly developing transit and communication, has knit all parts of the world so closely together, and so reduced time and distance, that for any nation to develop a purely indigenous archi tecture would mean that the material and spiritual status of its people had been untouched by modern inventions. Modern archi tecture therefore will be discussed not by geographical boundaries, but according to those influences—industrial, social, educational, governmental, and religious and memorial—that are the basic causes of all building development, and common to all nations. They have been placed in the order of their importance, consid ered in terms of capital investment and the number of people in volved.
