Letters 29.2

For what if one should chide the deaf or those who are speechless from birth or by illness? But you answer: “Why should I spare words? They cost nothing. I cannot know whether I shall help the man to whom I give advice; but I know well that I shall help someone if I advise many. I must scatter this advice by the handful. It is impossible that one who tries often should not sometime succeed.”
