2 With that end in mind, theorists have attempted to generate, whenever possible, universally applicable explanations of growth and development; alas, general theories have had to rely upon specific experience for their support and while such theories are valuable, they suffer from limitations not always made explicit. The peculiarities of different peoples and regions rarely are considered and theories often are divorced almost entirely from any historical or geo- graphical consideration. Theories are indispensable in organizing thinking so that sense can be made of an otherwise senseless plethora of disassociated facts; they are vital to under- standing. But theories are necessarily abstractions; they involve ideal, disembodied concepts of complex and real phenomena. Of necessity, they present reality in an unreal light. The danger is that theories, meant to describe the world in which we live, may take on the face of reality and come to be mistaken for the reality they only attempt to describe. As a result, the world may come to be viewed as more ordered, rational, and predictable than it really is. Perhaps it is really a matter of the interminable argument about first cause. Outside a totalitarian State, we do not view economic development as arising primarily essentially messianic in character. It knows the goal which all societies should seek. Marx's "communism," Rostow's "self-sustained growth," and Landes' "industrial- ization" are prophecies.
