Most REAL change is slow. Happiness and joy are the purpose of life. If we know that the future will be very dark or painful, then we lose our determination to live. Therefore, life is something based on hope.
That has been the great achievement of our age: to so thoroughly flood the planet with megabits that every image and fact has become a digitized disembodied nothingness. With magnificent determination, our species has advanced from Stone Age to Industrial Revolution to Digital Emptiness. We've become weightless, in the bad sense of the word.
The craft with which the world is made runs also into the mind and character of men. No man is quite sane; each has a vein of folly in his composition, a slight determination of blood to the head, to make sure of holding him hard to some one point which Nature has taken to heart.
