Things are simply the way they are. They don't give us suffering. Like a thorn: Does a sharp thorn give us suffering? No. It's simply a thorn. It doesn't give suffering to anybody. If
we step on it, we suffer immediately.
Why do we suffer? Because we
stepped on it. So the suffering comes from us.
If to enjoy even an enjoyable present we must have the assurance of a happy future, we are “crying for the moon.” We have no such assurance. The best predictions are still matters of probability rather than certainty, and to the best of our knowledge every one of us is going to suffer and die. If, then, we cannot live happily without an assured future, we are certainly not adapted to living in a finite world where, despite the best plans, accidents will happen, and where death comes at the end.
I believe that the destructive nature of society that now threatens the existence of the entire human world has much to do with human intelligence. The way to overcome all human suffering-that also is through human intelligence.
