retrogressions the progressive augmentation of the world
of It is to be clearly discerned in history. It is beside
the point of this conclusion whether the character of
finitude or that of so-called infinity, more precisely non-
finitude, belongs to the ** world-view " of a culture;
though certainly a " finite" world can well contain

grow. The individual can, to be sure, more and more
replace direct with indirect experience, he can " acquire
items of knowledge ", and he can more and more reduce
his using of the world to specialised " utilisation " ;

It is the obstacle ; for the development of the ability
