When, feeling has become blunted then what remains? Nothing. Then there is no sign of life. What remains is intellectuality expressing itself by the power of egoism. It is difficult to live in the world because selfishness is ever on the increase. Business and industry apart, even in friendship, in relationship the give-and-take has the greatest importance, worldly interest takes part in it. There is a certain fineness that belongs to human nature, a certain nobleness, a certain independence, there is a certain ideal, a certain delicacy, a certain manner that belong to human nature, and all these become blunted when the heart quality is left undeveloped.
