ABSTRACT
Before beginning to build, it is necessary to know what bricks are to be used, or, in modern terms, what must be the unit of construction. Times and fashions change and with them the units of material construction. So, too, with the constructs of Society; man changes his institutions, his customs and the external circumstances of his life and, in a manner, his own life with them. But Nature's laws are abiding. In the realms of Matter and Energy about which man has come to know so much, he accepts Nature's units of construction and works in obedience to her laws. In the realm of Living he has yet to recognise the unit with which Nature works; and to learn to use that unit. If man is to venture on the rebuilding of Society, he must take nothing for granted. The first question therefore is—With what unit does Nature build in the living world?
