“Through all ages men have tried to fathom the meaning of life. They have realized that if some direction or meaning could be given to our actions, great human forces would be unleashed. So, very many answers must have been given to the question of the meaning of it all. But they have been of all different sorts, and the proponents of one answer have looked with horror at the actions of the believers in another. Horror, because from a disagreeing point of view all the great potentialities of the race were being channeled into a false and confining blind alley. In fact, it is from the history of the enormous monstrosities created by false belief that philosophers have realized the apparently infinite and wondrous capacities of human beings. The dream is to find the open channel.
What, then, is the meaning of it all? What can we say to dispel the mystery of existence?
If we take everything into account, not only what the ancients knew, but all of what we know today that they didn’t know, then I think that we must frankly admit that we do not know.
But, in admitting this, we have probably found the open channel.”
