problems should be handled or what kind of help should be 
obtained from abroad. There is also a deeper need of replacing 
the traditional pattern of making decisions on the basis of 
authority by decisions to be made increasingly on objective 
grounds based on scientific and rational thinking. 
Perspective planning is indispensable. The need of pers- 
pective planning, especially in underdeveloped countries, may 
be stated very briefly in conclusion. It is necessary to increase 
the supply of consumer goods. To do this it is necessary to 
expand continually the production of capitel goods. Both 
would require an increasing supply of engineers and techni- 
cians. Industrial and technological developments would call 
for a rapid expansion of applied research which, in its turn, 
would require a sound foundation of basic research. 
The factor of time may be next considered. Factories for 
the production of practically any kind of consumer goods 
can be established in a year or two with the help of imported 
machinery or fuel. To develop the production of capital goods 
and energy would take it at least 10 or 15 years. To secure 
an adequate supply of engineering and technical personnel 
would require 20 or 25 years. To have enough scientists ot 
ability for both applied and basic research would take at least 
a generation or even more. It is clear that perspective plan- 
ning, looking 15 or 20 or 30 years ahead, is indispensable for 
all underdeveloped countries
