venience. If a natural system should be found to explain all the mutual 
relations of all the members of the system, it would be a dynamic one. 
8. CONSTRUCTION OF THE DYNAMIC SYSTEM. 
The question now arises as to how to construct the dynamic system. 
The best and simplest way of doing this is to take a static system like 
EnGier’s or BENTHAM-HOOKER’s, as a foundation, or rather as a framework, 
and to put it, so to speak, into a dynamic condition. To this matter, I shall 
return later on, but let us now proceed to discuss the reasons for so doing. 
However different may be the static system taken at first ag a framework, 
the dynamic system, after it is completed, is. ever the same in its real 
meaning. It is only the appearance of the system that varies with the 
framework. ENGLER’s system is different from BrnrHam-HooxkEr’s; but 
the difference is merely because of the difference of ENGLER’s view from 
BentHaM-Hooker’s. When we take Encier’s system as a framework or, so 
to speak, as a starting point, for the construction of a dynamic system, the 
latter system is quite the same in its real meaning as that construcied by 
taking Benroam-Hooker’s system. This work of construction is something 
like a cruise round the world. However much the starting point may be 
shifted, after the voyage is finished, the ports we have called at are all the 
same. Let me take another metaphor to explain my idea correctly. To 
establish natural relations, which is the principal object of constructing a 
natural system, is, as it were, to acquire a thorough understanding of the 
features of a mountain. As an example, take Mt. Fuji, that fitting emblem 
of the Japanese nation and my special favourite since my youth. As a 
natural system has several different aspects, so has the volcano. As the 
former should be considered from different points of view, so should be the
