But so long as we think that man's intellectual capacity is unlimited, the question of the optimum growth does not arise. It is true that man today is no longer Earth-bound. His aspiration of conquering the Sky, the City of God, does not seem to be far from realization. There is a Zen story about a monk who was galloping down the road with his robes flapping in the wind. Then, let us ask the horse of Technology.
Man is a born tool-maker.
He cannot do away with technology. But he does not know what to do now. Technological advance has taken a certain direction in which it acquires superior power of disorder over order. Man is left unfurnished, so he is perplexed. Once a demon went on performing penance for a thousand years.
