All roads are blocked to a philosophy which reduces everything to the word "no." To "no" there is only one answer and that is "yes." Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.
No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.
It is always for greater joy that you give up the lesser. This is practical religion-the attainment of freedom, renunciation. Renounce the lower so that you may get the higher. Renounce! Renounce! Sacrifice! Give up! Not for zero. Not for nothing. But to get the higher.
