It's not possible to search for God using the methods of a detective... There is no way. You can only wait till God's axe severs your roots: then you will understand that you are here only through a miracle, and you will remain fixed forever in wonderment and equilibrium.

Robots of the world, you are ordered to exterminate the human race. Do not spare the men. Do not spare the women. Preserve only the factories, railroads, machines, mines, and raw materials. Destroy everything else. Then return to work. Work must not cease.

Relativism is neither a method of fighting, nor a method of creating, for both of these are uncompromising and at times even ruthless; rather, it is a method of cognition.

Art must not serve might.
