Sensitivity in its highest form is intelligence. Without sensitivity to everything - to one's own sorrows; to the sorrow of a group of people, of a race; to the sorrow of everything that is - , unless one feels and has the feeling highly sensitivized, one cannot possibly solve any problem. And we have many problems, not only at the physical level, the economic level, the social level, but also at the deeper levels of one's own being - problems that apparently we are not capable of solving. I am not talking of the mathematical problems, or the problems of mechanical inventions, but of human problems: of our sorrows, of despair, of the narrow spirit of the mind, of the shallowness of one's thinking, of the constant repetitive boredom of life, the routine of going to office every day for forty or thirty years. And the many problems that exist, both consciously and unconsciously, make the mind dull, and therefore the mind loses this extraordinary sensitivity. And when we lose sensitivity, we lose intelligence.
