Without man and his potential for moral progress, the whole of reality would be a mere wilderness, a thing in vain, and have no final purpose. - Immanuel Kant

Thus, if materialism is inadequate to explain my existence, then spiritualism is equally insufficient for this purpose.

Es ist überall nichts in der Welt, ja überhaupt auch außer derselben zu denken möglich, was ohne Einschränkung für gut könnte gehalten werden, als allein ein guter Wille.

[W]hat alone has value is the use to which life is put and the end to which it is directed. The value of life has to be created by man, it cannot be obtained through luck but only through wisdom. He who is anxiously concerned over losing his life will never enjoy life.
