In recent years our knowledge of modern technology has increased considerably, and as a result we have witnessed remarkable material progress, but there has not been a corresponding increase in human happiness. There is no less suffering in the world today, and there are no fewer problems. Indeed, it might be said that there are now more problems and greater dangers than ever before. This shows that the cause of happiness and the solution to our problems do not lie in knowledge of material things.
