"Yes, that's true."
"When Neil Armstrong set foot on the moon, he said 'One small step for man, one giant leap for mankind. With these words he summed up how it felt to be the first man to set foot on the moon, drawing with him all the people who had lived before him. It was not his merit alone, obviously.
"In our own time we also have completely new problems to face. The most serious are those of the environment. A central philosophical direction in the twentieth century is therefore ecophilosophy or ecosophy, as one of its founders the Norwegian philosopher Arne Naess has called if. Many ecophilosophers in the western world have warned that western civilization as a whole is on a fundamentally wrong track, racing toward a head-on collision with the limits of what our planet can tolerate. They have tried to take soundings that go deeper than the concrete effects of pollution and environmental destruction. There is something basically wrong with western thought, they claim."
